Energy-saving doors and windows on the market are mainly doors and windows, which are also the most widely recognized energy-saving doors and windows by consumers. The system windows are made of heat-insulating and broken-bridge aluminum profiles and hollow glass, which have the functions of energy saving, sound insulation, noise prevention, dustproof, and waterproof. What should I pay attention to when buying energy-saving doors and windows?

1. Performance of hardware accessories

Hardware accessories occupies a very important position in the design of system energy-saving doors and windows. The quality of hardware accessories affects the performance indicators of doors and windows. The repeated opening of doors and windows is realized by hardware accessories, so choosing high-quality door and window accessories is also the key. The quality of hardware accessories is directly related to the quality of doors and windows processing.

2. Thermal window profile design In the system energy-saving door and window design, the design of the thermal window profile is the core part of the entire design. The quality of the profile design determines the performance and quality of the door and window. The principle of insulation is that the non-metallic insulation tape (nylon 66) and the two parts of the door and window section are cleverly combined into a heat insulation section by mechanical roller pressure.

The section design process mainly considers the influence of wind load, comprehensive strength, rigidity and stability and other requirements, optimizes the design, and makes the inertia moment I and cross section resistance moment W of the section exhausted under the most economical section area conditions. It might be big. Insulating strips are embedded in the cavity, called the "King of Insulation" as PU resin, which has a more significant energy-saving effect on preventing heat diffusion.

Energy-saving doors and windows on the market are mainly doors and windows, and they are also the most commonly recognized energy-saving doors and windows by consumers. What should you pay attention to when shopping for energy-saving doors and windows?

1. Look at the production quality. The decorative surface of doors and windows should not have obvious damage, which means that the protective film on the surface of doors and windows should not have scratches. There should be no obvious chromatic aberration on the colored surfaces of adjacent components on doors and windows. There should be no aluminum chips, burrs, oil spots or other stains on the surface of doors and windows, and there should be no spilled adhesive at the assembly joints.

2. Look at the material. Whether it is heat insulation and door and window profiles, the wall thickness of the main profile should be greater than 1.4mm; the color of the same aluminum alloy structural profile product should be the same, if the color difference is obvious, it is not suitable to purchase; check the surface of the aluminum alloy construction profile material, there should be no Dent or bulge;

3. Look at the assembly quality. Repeat the switch to see whether the switching force is too large; whether the sealing strip is firm; whether the hardware assembly is complete; whether the overlap of the casement window frame meets the requirements (the standard requires that the casement window is not less than 6mm, and the sliding window is not less than 8mm).

4. Check whether the glass is hollow structure glass.

We live in the home decoration of aluminum doors and windows getting more and more applications, but in the face of many brands in the market, coupled with a large number of customers buying products are not very familiar, so there is some confusion, what issues need to pay attention to aluminum doors and windows?

1. Observe the quality management of aluminum doors and windows

At the time of purchase, we can conduct quality inspection through operation, that is, observe through the aluminum alloy door and window switches, specifically the sealing of the switch, so that the mobility, air tightness, and water repellency can better experience the quality of the product.

2. Test by material

Aluminum alloy doors and windows are made of aluminum alloy and wood, so the two materials used in high quality should also be excellent.

3. Check the appearance of aluminum doors and windows

Through the quality of aluminum doors and windows, we can also find out some problems through observation. For example: Whether the lines can be smooth, whether the pattern design has perfect cleaning, the heavy texture of the paint surface, the smoothness of the surface, the uniformity of the color, etc.

Someone will ask the question, the hollow glass doors and windows in the home have only been used for two or three years, why does it seem to be "fog" inside?

If the edge of an insulating glass is not tightly sealed, it will affect our insulating glass and door and window enterprises and may "fog". Therefore, when purchasing aluminum alloy doors and windows, we must pay attention to the selected insulating glass. The insulating glass must meet the requirements of our own country; the sealant must be of high quality. The good glass sealant includes the special structural glue for the curtain wall system, etc.

The role of desiccant:

1. Absorb the moisture sealed in an air;
2. Absorb volatile organic solvents;
3. The water vapor absorbed by the enterprise into the air layer during the forecast period of the insulating glass service life. In summary, we already know the role of desiccant. If the hollow glass is mainly used for fogging, what should we do and how to choose a desiccant?

The water tightness and air tightness of aluminum alloy doors and windows are the key to measuring quality. According to the summary of actual engineering experience, pay attention to the following ten points, aluminum alloy doors and windows will not leak air and water. Aluminum alloy doors and windows The doors and windows made of aluminum alloy extruded profiles as frames, stiles and fans are called aluminum alloy doors and windows, or aluminum doors and windows for short.

1: Since the general aluminum alloy doors and windows of enterprises are recessed, the top of the window must be a dripping beak to prevent the capillary phenomenon of rainwater from occurring.

2: Aluminum alloy doors and windows should be coated with waterproof coating about 300 mm away from the window, and lead water oil should be coated on the gray position before using the waterproof coating.

3: The windows must be sealed with concrete that has been added with waterproofing agent. Please note that waterproofing agent must be added.

4: Waterproof sealant should be applied to the transfer position around the window frame and other materials.

5: Fully open the top of the windows and add wall panels to prevent rainwater from flowing upwards into the room from the opening.

6: The glass aluminum frame is filled with sealing material, and the tape is not used.

7: The construction should strictly require the surrounding interfaces to be processed.

The perfect organic combination of a performance system for system doors and windows requires consideration of a series of important functions such as water tightness, air tightness, wind pressure resistance, mechanical strength, heat insulation, sound insulation, anti-theft, sun shading, weather resistance, and operating feel. Considering the comprehensive results of the performance of equipment, profiles, accessories, glass, viscose, and seals, all of them are indispensable, and finally high-performance system doors and windows are formed.

1 Causes of corner problems

1.1 Temperature difference

Due to temperature changes, the material itself usually has a certain stress effect, which is manifested as a linear expansion/contraction ratio. The perfect organic combination of a performance system for system doors and windows requires consideration of a series of important functions such as water tightness, air tightness, wind pressure resistance, mechanical strength, heat insulation, sound insulation, anti-theft, sun shading, weather resistance, and operating feel. Considering the comprehensive results of the performance of equipment, profiles, accessories, glass, viscose, and seals, all of them are indispensable, and finally high-performance system doors and windows are formed.

The dimensional change of aluminum alloy profile in the normal use temperature range, that is, the calculation formula of linear expansion/shrinkage rate is:

In the formula, the changed length;

Original length;

The coefficient of expansion and contraction in the range of -4050 ° c is 2.410-5 ° c;

The temperature change value in degrees Celsius.

According to the formula, the change of 1m long aluminum alloy profile under the temperature difference of 90°C in the range of -40 to 50°C: This rate of change of 2.16mm is sufficient to cause the corners of doors and windows to lose mutual position or deformation, resulting in a decrease in corner strength and sealing performance. Energy saving is more difficult.

1.2 External force

Many companies are ubiquitous and unavoidable. The deformation temperature stress caused by the inevitable and accidental external forces will cause the corner problems of the doors and windows, such as the production, transportation development, and the construction management of the installation project. Collision, knocking; After the installation of doors and windows is completed, long-term analysis of the weight of its own products and the effect of static stress on window openings and wall deformation; opening and closing of windows, wind pressure, environmental sound waves and other vibrations pass through. These data can cause the air-tightness, heat insulation, sound insulation, and dust-proof performance of doors and windows to continue to decline. In severe cases, it will increase the deformation of doors and windows, which has become the main research reason for energy consumption of doors and windows.

Energy-saving building doors and windows refer to doors and windows whose thermal insulation performance and air environment penetration safety performance do not meet the current design curriculum standards for energy-saving building projects. Measures to improve the effect of their own thermal insulation doors and windows energy-saving policies are as follows:

1. Reasonable and correct selection of window types The types of doors and windows are divided into different types, and the energy-saving effects are also different. Generally, external wall windows have three basic forms: fixed windows, casement windows, and sliding windows.

The heat loss of fixed windows due to natural convection is very small. The thermal conductivity of the window frame and glass is the main risk factor that affects the thermal insulation performance of the entire aluminum alloy window. Reasonable use of window frames and glass packaging materials will be taken Very good thermal insulation effect.

Casement windows are usually mechanically sealed with more high-quality rubber strips. The sealing performance is very good. It is also difficult to truly form urban air convection between the window sash and the window frame. Similar to fixed windows, casement windows also have excellent performance. energy saving effect.

The sliding window pulley or sliding block push-pull method is simple and convenient to use, save network space, and can be easily disassembled. It is widely loved by consumers in China.

2. The program design of scientific knowledge node should adopt high-performance sealing technology around the heat insulation doors and windows to reduce the heat loss of polluted air and improve airtightness, watertightness, sound insulation, heat preservation, heat insulation and other main physical and chemical properties. At the same time, the design of sealing strips, composite profiles, drainage grooves, etc. needs to be relatively rationally planned and designed based on the surveyed local actual situation data.

3. Reasonable demand selection of reading materials cannot be based on historical architectural cultural requirements, and reasonable consumption and selection of active materials, such as aluminum alloy, heat insulation strips, glass, seals, and hardware.

4. To ensure the surface quality of the processed doors and windows, various mechanized sawing, cutting and profiling must be adopted in a timely manner during the processing of doors and windows; all connecting parts should be soaked with mortise glue; the closing part of all rubber strips should be bonded.

5. Improve the professional level of internal installation. Dry construction should be adopted for thermal insulation doors and windows, and expansion screws should be used to connect them. The contact surface of the aluminum wall should be coated with anti-corrosion materials. The gaps should be filled with green, ecological and environmentally friendly thermal insulation and sealing materials, and the exposed areas should be sealed for construction. glue.

For the door and window owners of many decoration shops, there are too many door and window brands on the market, and there are many models. For the door and window Xiaobai, how good are the doors and windows? ? Today, I just need to tell you a few points to understand.

Doors and windows include door and window profiles, hardware, window screens, glass, etc. Among them, aluminum and hardware are crucial. This is the key. How does it choose aluminum? Those owners of doors and windows don't only need to understand what is the choice of Guangdong Aluminum on-line anti-counterfeiting labels, why do they say that? Since many brands buy cheap aluminum adhesive protective films by themselves, they have become their own brands. These brands cannot distinguish between true and false. This is what makes companies stick to what brand, but the real big brands have their own safety, so For example, Feng Aluminium has anti-counterfeiting labels, you don’t even know what doors and windows, and then choose the big brand aluminum anti-counterfeiting labels on the right.

Why do we choose a big brand as aluminum?

1. The door and window profiles of major brands have their own anti-counterfeiting and are not easy to counterfeit. Consumers do not have to worry about buying fake products at high prices.

2. Large-brand door and window profiles are national inspection-free products. The national standard minimum aluminum-containing wall thickness is 1.4MM, which is not lower than the standard aluminum in the market, but it is often unknown that the wall thickness of aluminum profiles meets the national standard.

We all know that doors and windows are all colored, and there are thousands of colored doors and windows, then the color of plastic steel doors and windows, plastic steel is relatively single, mainly white, with colored plastic steel doors and windows, there are only a dozen colors, color What is the difference between doors and windows and colored steel doors and windows?

1. The colored doors and windows are sprayed out with aluminum contours, which do not fade, and the colored plastic steel doors and windows are covered with film, that is, the outer white plastic steel doors and windows are covered with a layer of color through high temperature. This kind of colored plastic steel doors and windows are easy to peel off. But it is not easy to fall off.

2. Color doors and windows generally mainly include powder spraying and electrophoresis. In addition to film coating, there is another color co-extrusion profile color for color plastic steel doors and windows. Color co-extrusion is generally used for large-scale residential projects, and small-scale reservations are generally used. It's hard to decide. The system windows are made of heat-insulating and broken-bridge aluminum profiles and hollow glass, which have the functions of energy saving, sound insulation, noise prevention, dustproof, and waterproof.

The advantages of aluminum doors and windows, plastic windows are rolled into two types, which have a good performance-to-price ratio and have become an ideal choice.

In principle doors and windows, the profile is A, B or multiple sides penetrate the insulating tape, the aluminum forms a break, effectively preventing heat conduction and thermal insulation. The thermal conductivity of insulated doors and windows is reduced by 40 to 70% compared to non-insulated aluminum doors. Doors and windows can achieve six types of sealing structures, a reasonable vapor separation chamber, and successfully achieve gas pressure balanced water, significantly improving watertight and airtight doors and windows.

Insulation strips, doors and windows, as the core component, explain the total aluminum ore of the insulation knowledge strip. The raw material insulation tape is PA66 nylon tape, which has sufficient longitudinal and transverse tensile strength, good aging resistance, and some low-quality insulation tapes. In the market used in China, the reason is that the heat insulation doors and windows have significant quality problems, and the insulation effect of curtain walls (insufficient strength will cause the insulation of the aluminum tape joints to decompose from heat) cannot be guaranteed.

The editor heard and understood the very principle of doors and windows, not only smiled, but also gave a thumbs up to the doors and windows.

Doors and windows can be extruded from different primary aluminum ingots. The inner wall of the aluminum profile is smooth without any roughness. It is a real pure aluminum ingot and does not contain any impurities. The wall thickness is better than the national standard 1.6MM aluminum profile. Door and window companies adopt the six-channel sealing system design and development concept, which greatly increases the water tightness and airtightness of our doors and windows.

I believe that through Shao, we will have a further understanding and understanding of aluminum alloy doors. Of course, there are many markets for aluminum alloy door products, and the quality is not balanced. Many people tend to fall into some misunderstandings when choosing aluminum alloy doors. Then aluminum alloy doors and windows What are the purchasing skills? Let's take a look at the following introduction:

Misunderstanding skills for system door and window purchase:

1. System door and window shopping error:

1. Heavy and beautiful:

Only value the diversity of colors and ignore the inner quality. The double-layer insulating glass and triple-layer laminated glass used are much better than ordinary glass. The thickness of the oxide film should reach 10 microns, and you can gently scratch the surface of the glass profile to see if the oxide film on the surface can be erased. If it can be erased, that's good.

2. Heavy thickness:

You only need to choose the ones that meet the requirements of our country’s relevant laws and regulations. The wall thickness of the aluminum profiles for doors and windows should be no less than 1.2 mm. The thickness of the doors and windows for the system design is from 0.

The aluminum alloy doors on the market can be divided into push-pull aluminum alloy doors, open aluminum alloy doors, and folding aluminum alloy doors. Their characteristics are different. The following introduction:

1. Sliding door:

It refers to a door that is opened and closed by sliding left and right in the width direction. The perfect organic combination of a performance system for system doors and windows requires consideration of a series of important functions such as water tightness, air tightness, wind pressure resistance, mechanical strength, heat insulation, sound insulation, anti-theft, sun shading, weather resistance, and operating feel. Taking into account the comprehensive results of the performance of equipment, profiles, accessories, glass, viscose, and seals, none of them are indispensable, and finally high-performance system doors and windows are formed. Common sliding doors have two forms: exposed sliding doors and railings outside the wall, concealed sliding doors refer to sliding doors with the door and the railing in the middle of the wall. The sliding door has the characteristic of occupying a small space when opening and closing, which can make full use of indoor space.

2. Open the door:

It refers to a door that opens horizontally with a stile as its axis. Swing doors are the most commonly used type of door. According to the different opening directions, it can be divided into two types: inward opening and outward opening. It is mainly determined by its function and the need to occupy as little interior design space as possible after opening. Generally, the inner door of the building usually opens inward, while the outer door and emergency door of the building often open outside.

3. Folding door:

Folding doors refer to doors that can be folded during the opening process, and can be divided into two basic types: flat folding doors and sliding folding doors.

Taking home decoration materials as an example, various energy-saving door and window products have become popular. Compared with traditional door and window products, what are the advantages of energy-saving doors and windows? Today, take everyone to find out.

Advantages of energy-saving doors and windows:

1. Energy saving:

The first is energy-saving doors and windows. Literally, we also know that its biggest feature is energy saving and environmental protection. Some people say that there is only energy saving and environmental protection. Where are its energy saving and environmental protection features? Its first characteristic is its sufficiency. Because its structure advocates convenience and lightness, it occupies a small area and saves us a lot of raw materials for decorative doors and windows. This is one of its energy saving and environmental protection features, and its ventilation effect is good. Due to the good ventilation effect, our room is always full of fresh air. With this function, we don't need to buy a ventilator to keep fresh indoor air. With it, we don't need to buy a ventilator, which not only saves the cost of buying a ventilator, but also saves the power system that drives the ventilator, which saves us a lot of electricity and a small amount of money. The above characteristics are all energy saving and environmental protection.

2. Beautify decoration:

In addition to its energy-saving, green and environmentally-friendly development characteristics, it can also have a certain role in beautification and decoration. Due to its unique shape and structural design characteristics, it plays a beautifying role in improving our living and living environment. Energy-saving doors and windows companies because of its The peculiar configuration adds a lot of student color to our house, and provides people with a feeling of being bright before their eyes. With its beautification, we need to feel a lot more comfortable, and we can do things for you with less effort. , It saves us a lot of time and energy.

3. Practical:

Energy-saving doors and windows also have practical advantages. Because of their material and structure, their service life is much longer than ordinary doors and windows. It is energy-saving for us, at least we have bought a lot of unnecessary things.

If you want to make the indoor soundproof doors and windows products have a long service life, you must pay attention to the selection and maintenance of soundproof doors and windows. Finally, how to choose and maintain soundproof doors and windows? Take a look at the following:

How to choose and maintain soundproof doors and windows;

1. How to purchase soundproof doors and windows companies:

1. The weight of the door panel:

The effect of the soundproof door is directly related to the density of the material, so the higher the density, the better the sound insulation effect, and the sound insulation effect is relatively better.

2. The thickness of the door panel:

The thicker the sound insulation effect of the surface board, the general wooden door surface board should be 8mm thick, and the surface board thickness is also better, but the cost will increase, but: the iron plate fire door surface iron is 3mm thick, and the sound insulation effect is also good.

What are the materials for sound insulation and doors and windows:

1. Vacuum glass doors and windows:

The main feature of vacuum glass is that it facilitates the vacuum mute principle and prevents noise from entering the room. The working principle of this product is also very simple, that is, two glass panels of the same size are installed on the basic door and window frames.

2. Laminated glass:

Glue glass has also been widely used in the installation of soundproof doors and windows at home. Its basic sound insulation principle and vacuum glass use the independent space between the glasses to improve the sound insulation effect. The glue glass is not too close to vacuum glass when installed correctly and sealed. Big difference.

3. Hollow glass:

Because there is gas between the two layers of glass, the insulating effect of insulating glass is not as good as vacuum glass, but it is sufficient for small and inconspicuous residential areas, and it is more friendly to the people than the first two types of soundproof glass.

The above is a brief introduction to the commonly used materials for soundproof doors and windows. I believe that after the above introduction, everyone will have a further understanding and understanding of soundproof doors and windows.

The reason why door and window companies are called doors and windows is because they have heat insulation strips to block the disconnection. If we do not have a heat insulation strip for aluminum doors and windows, we can only use aluminum alloy doors and windows instead of doors and windows. What are its different characteristics?

The door and window insulation strips are black nylon strips, usually with electronic coding, according to the different aluminum profile manufacturers and names, but generally have the PA66 logo, which indicates that the batch of doors and windows are all nylon insulation strips, and they are doors and windows that meet the requirements of national standards.

1. On the surface. The nylon insulation strips for doors and windows are black and matte. Usually, these strips are marked with trademarks and product specifications, with an interval of 60-80 cm. Laser jet coding is smooth, no shrinkage, no pores, no scratches, no mold extrusion marks, and glass fiber distribution with special mineral luster can be seen, and there is no trace on the end of the heat insulation strip; other imported or domestic nylon heat insulation strips are gray Black or dark black, without any trademarks, the strips are rough, there are obvious die extrusion marks and die dividing lines on the end of the die, the die has loose shrinkage holes, and the PVC heat insulation strips are bright black without any trademark marks , The bar is rough, the die extrusion marks are obvious, there are a lot of loose shrinkage holes, and the head size is asymmetrical and irregular.

2. Break the experiment. Take the I type 25cm sample for manual breaking experiment. When the door and window nylon heat insulation strip is bent, it can feel good toughness and strength. It will not break when the two ends are folded, even if the fracture is slow fracture; other imports Or domestic nylon heat insulation strips are either obviously brittle, and multi-stage cracking occurs when there is a certain distance between the two ends of the bending (due to uneven glass fiber particles), or the toughness is obvious, repeated bending many times (the glass fiber content is insufficient) Caused by); PVC insulation strips are very soft, basically weak, and will not break after repeated bending.

3. Ordinary students ignite to conduct experiments. Nylon heat insulation strips for doors and windows are not easy to ignite. They show a light yellow flame when they burn, while PVC heat insulation strips are flammable. When they burn, they turn blue to represent the flame, and release a large amount of pungent black produced by the enterprise as smoke.

4. High temperature complete combustion test. Nylon insulation strips can be seen after the door is completely burnt with high temperature deposits and uniform black fibers; or other high-temperature nylon insulation strips in China or imported are completely burned with complete combustion or basically no fiber deposition and uneven fiber deposition; PVC insulation is completely burned at high temperatures There is no deposit on the rod.

Aluminum alloy doors and windows include wood and plastic composite doors and windows that use aluminum alloy as the base material of the force-bearing member (the rod that bears and transfers its own weight and load), referred to as aluminum-wood composite doors and windows, and aluminum-plastic composite doors and windows. Today, the editor and we are going to discuss the quality of the aluminum doors and windows broken bridge test method.

When consumers buy and use broken bridge aluminum doors and windows, we can distinguish whether the aluminum alloy door and window system is of high quality from the raw materials, the surface of the doors and windows, the heat insulation strips and the internal processing of the enterprise. Nowadays, consumers like to buy products of big brands. Yes, the product design of big brands is more socially secure. I believe that as a Chinese consumer, I know the truth.

From a large amount of raw material aluminum, but the difference is not big, mainly depends on the thickness of the aluminum doors and windows of the broken bridge, the thickness of 1.4mm aluminum is the national standard, if the thickness of the compressive strength is not, the wind will aggravate the disease. Then the surface of the aluminum layer is oxidized. The oxide film is a key corrosion, abrasion and other characteristics of aluminum doors and windows. If the thickness of this oxide film does not reach the entire bridge aluminum doors and windows, it will have a huge impact, of course, in addition to oxidation There are other methods for the process, but consumers need to test.

The key to insulation is broken aluminum, and the insulation performance of aluminum doors and windows, broken bridges and bridges. When buying doors and windows, you must check the test report. Insulation strips. The insulation of the strips is plastic. It is better to make the added fiber glass bearable. High temperature glass will not deform under high temperature or low temperature environment.

The perfect organic combination of a performance system for system doors and windows requires consideration of a series of important functions such as water tightness, air tightness, wind pressure resistance, mechanical strength, heat insulation, sound insulation, anti-theft, sun shading, weather resistance, and operating feel. Considering the comprehensive results of the performance of equipment, profiles, accessories, glass, viscose, and seals, all of them are indispensable, and finally high-performance system doors and windows are formed. You can't miss it.

1. Sealing strip

There will be a ring of sealing rings around the doors and windows. The sealing rings are generally rubber, with good elasticity and toughness, and play a sealing role. They can also play a certain buffer effect on the door and window accessories. The seals are bright in color, uniform in thickness, moderate in hardness, and can be used for three or four years, and they will be broken after a year and a half of poor quality.

2. Sound insulation strip

There will be a certain gap between the door and the floor, and a small gap has a greater impact on the sound insulation of the door. In fact, the bottom of the door can be nailed with a sound insulation layer, some made of fiber cloth, and some made of plastic brush. The sound insulation material is thin, but it is enough to fill the gap and will not affect the opening and closing of the door.

3. Track rubber strip

The sliding doors and sliding windows are embedded in the track or frame, and the window frame and the outer frame are made of metal. Even if the doors and windows are closed tightly, there is still a certain gap between the two. Good doors and windows have a layer of rubber strips on the frame and track, which can play a sealing role and prevent the doors and windows from falling off. Of course, there is no sharp metal friction when opening and closing doors and windows.

4. Cushion pad

We used too much force when opening doors or sliding windows. When the doors and windows hit the door frame or window frame, there would be "vibration or noise". A long time learning will affect the life of the doors and windows, and may even shatter the glass . An important cushion rubber pad can be installed at the corner of the frame of the door and window system to reduce the effort of enterprise cushion management.

5. Rubber cap for drainage hole

The lower layer of the door and window frame is provided with multiple drainage holes to facilitate the drainage of rainwater accumulated on the frame track.

6. Glass layering

After the door and window glass is installed, the glass rod should be sealed once. In addition to increasing the seal, it is more important to increase the firmness of the glass to avoid falling off due to strong wind or other external forces. Most of the glass rods are rubber strips, but some will be replaced by silica gel. Although silica gel can be sealed, it is easy to fall off in the sun for a long time.

Both doors and windows can play the role of a space barrier, and also play a role in protecting the safety of the bedroom. The system windows are made of heat-insulating broken bridge aluminum profiles and hollow glass, which have the functions of energy saving, sound insulation, noise prevention, dustproof, and waterproof. So what should owners pay attention to when buying high-end doors and windows?

1. Look at the material

The material of the door and window cover is very important to the quality of high-end doors and windows. If the doors and windows are deformed, there is a problem with the door and window cover.

2. Door core

What kind of problems do the door core need to look at the students? It depends on what the company uses and the material, whether it is the real material.

3. Look at the test report

There are many kinds of materials. First of all, it depends on whether environmental protection meets the standards.

4. Watch the production equipment of door and window manufacturers

To see if the production equipment of the door and window manufacturer is complete, use advanced production equipment to produce high-quality door and window products: only by handling the pressure resistance and corrosion resistance of the contour, can the abrasion of the contour be reduced, reducing the chance of deformation of the door and window product, and extending the use life.

5. Choose factory direct sales

At present, many dealers have severely blackmailed consumers, which requires consumers to identify themselves. Generally speaking, large-brand door and window manufacturers and corporate distributors will set prices uniformly across the country, and then make appropriate adjustments according to the consumption level of each region. Even if there is a degree of fluctuation, it is generally not too large.

6. Look at the installation level

How important is the installation; if it is installed improperly, it will directly affect the aesthetics of doors and windows and the effect of future use.

7. Look at brand awareness

How to make aluminum alloy doors and windows help your home business save money? The editor has two coups, let's take a look together.
1: Aluminum alloy doors and windows can be equipped with "sealing strips"

Due to the production and installation of some aluminum alloy doors and windows, the gaps are not tight, the cold weather is ventilated, the quality of wearing the summer high temperature is poor, and the sound insulation effect is not good. We recommend that you install aluminum alloy doors and windows with "seals", this seal installation is simple, low cost, the effect is very obvious, it can save energy for you. Even if you have a house seal at home, you should also check that in the season, when the wind is blowing, there is still a certain gap between the seams of the hand and the feeling, if we feel the wind, we must replace it as soon as possible .

2: The balcony uses aluminum alloy doors and windows to add an "insulation layer"

In order to make the interior design more spacious, many students in home education will remove the balcony aluminum alloy doors and windows connected to the house during the decoration, or the company simply does not directly use their own closed balcony and do not install the balcony aluminum alloy doors and windows.

Frequently used, different consumers will consult, what is the difference and difference between plastic steel doors and windows and doors and windows, we need to talk about it in the article before, and we will not talk about it today. Whether it is the difference in learning materials, it is mainly a heat insulation. There are differences in sound insulation, heat preservation and sealing. The key content of today's development tells what is the difference between the sound insulation and sealing problems of plastic steel doors and windows than doors and windows?

1. Sound insulation: Why is the sound insulation of plastic steel doors and windows not as good as doors and windows? Because the performance of the sealing system of plastic steel doors and windows is not as good as that of doors and windows, and the sealing treatment is not good, naturally the sound insulation will be worse than that of doors and windows.

Aluminum alloy doors and windows The doors and windows made of aluminum alloy extruded profiles as frames, stiles and fans are called aluminum alloy doors and windows, or aluminum doors and windows for short. Aluminum alloy doors and windows include wood and plastic composite doors and windows that use aluminum alloy as the base material of the force-bearing member (the rod that bears and transfers its own weight and load), referred to as aluminum-wood composite doors and windows, and aluminum-plastic composite doors and windows. The perfect organic combination of a performance system for system doors and windows requires consideration of a series of important functions such as water tightness, air tightness, wind pressure resistance, mechanical strength, heat insulation, sound insulation, anti-theft, sun shading, weather resistance, and operating feel. Considering the comprehensive results of the performance of equipment, profiles, accessories, glass, viscose, and seals, all of them are indispensable, and finally high-performance system doors and windows are formed. Broken bridge aluminum doors and windows use thermally insulated broken bridge aluminum profiles and hollow glass, which have the functions of energy saving, sound insulation, noise prevention, dustproof, and waterproof.

2. Airtightness: Plastic steel is worse than doors and windows for sealing. We don't need to talk about it. Why is it so? Because plastic-steel doors and windows are equipped with rubber strips on the window frames, and you can install a buckle after installing a glass. This method of fastening strips with adhesive strips is much worse than applying glass glue between windows and glass companies. When doors and windows are installed, people inside and outside the window and the glass company must apply glue. The second analysis is the difference between the rubber strips on some windows. Take the casement window of plastic steel door and window as an example. The plastic steel casement window mechanism has at most two rubber strips, and the most common 55 series of door and window systems also have problems. Three rubber strips, better door and window design, and ten sealing product series to improve the sealing effect layer by layer, so they can see if the plastic steel door and window project is much worse than the door and window in the sealing performance.

1. Generally include residential buildings: neither the street nor the trains or planes. For such a community design, it is the most ideal choice to use door and window companies as soundproof and sealed windows. There is no more suitable than this kind of window. It is needed here. Our country's target is generally considered in terms of community management.

2. The neighborhood where the street train passes by: This kind of management area for ordinary enterprises has very high requirements for sound insulation. You can choose the 70 series or 80 series for doors and windows, and the glass material to choose double-layer hollow glass. This kind of window has a general sound insulation. The sound insulation effect of the residential area is better. For consumers who are not sensitive to the i noise problem, it can be said that China has good sound insulation.

3. Owners, the sound effect of ordinary insulating glass can not meet their needs for high sensitivity to noise or sleep requirements. We know that low-frequency noise of cars, trains, airplane noise, and insulating glass are very loud and high-frequency noise, but for low-frequency noise The insulation is relatively poor.
