The quality of doors and windows varies greatly, how to choose doors and windows

Good materials can make really good things, so when choosing doors and windows, we must first clarify the materials used for doors and windows. It can be considered from the following points:

1.Know the quality from the material.

Measure a quantity: the wall thickness of the main profile of the broken bridge insulation aluminum profile should be greater than mm.

Take a look: the color of the same aluminum alloy profile is consistent, there is no dent or bulge on the surface, no open bubbles (white spots) and ash slag (black spots), as well as obvious defects such as cracks, burrs, and peeling.

Scrape: Scratch the surface of the aluminum profile, and the oxide film on the surface is not wiped off.

2.Knowing the performance from the structure.

Wind resistance: The frame material, opening and closing method and the thickness of the glass determine the stability of the door and window windproof, and the doors and windows made of aluminum alloy and double glass structure perform better in terms of wind resistance.

Watertightness: Insulating glass has stronger watertightness than ordinary glass structures, because it is effectively sealed between several layers of glass and loaded with a desiccant that absorbs water vapor, so that there is no water vapor and dust in the glass.

Air tightness: Double or triple vacuum LOW-E glass, plus double rubber sealing strips, can effectively isolate the convection of air on both sides when the doors and windows are closed.

3.Know the quality from the components.

Joints: the inner and outer corner seams of doors and windows are spliced smoothly and seamlessly; The components are firmly connected, and corrosion-resistant filler materials are used to make the connection part sealed and waterproof.

Welding: There are no defects in the parts of door and window welding, such as open welding, missing welding, etc.

4.Know the production from the details.

Hardware accessories: excellent quality accessories feel thick, the surface protective layer is dense and shiny, and there are no scratch marks.

Buffer glue: Doors and windows are equipped with buffer glue or anti-collision glue to protect the door leaf from strong collision.

5.From the sign to know**.

Production mark: Regular manufacturers have clear signs on the obvious parts of aluminum alloy doors and windows, including the name of the manufacturer or trademark, product name, product model or mark, manufacturing date or number.

6.Know the positioning from **.

Compare one: a number of price comparisons, understand the laws of the market, if the product is more than 20% lower than the market price, it is very likely to be shoddy inferior products, pay attention to careful purchase, I hope it will help you!

One: recognize the material and recognize the surface treatment process people in the store to choose doors and windows, the boss will generally tell you, this is the wide material, the product is good, more expensive than the Sichuan material, the material is the profile produced by the Guangdong aluminum profile factory, most of the material is the South China Sea aluminum ingot, the Sichuan material is the profile produced by the Sichuan profile factory, most of the Sichuan material uses the Yangtze River aluminum ingot, the South China Sea aluminum ingot is purer than the Yangtze River aluminum ingot, and it is more expensive.

2: Recognize the material type of doors and windows A perfectly designed window should have the characteristics of silence, heat insulation, heat preservation, waterproofing, drainage, safety, solidity, durability and beauty.

Three: recognize hardware accessories The quality of hardware accessories directly determines the durability and convenience of doors and windows. It is recommended to ask the merchant what brand accessories are used, and the more well-known ones are German Haobo brands.

Four: recognize the quality of workmanship The effect of doors and windows made by good machinery and equipment is generally not bad, so it is recommended to choose brand doors and windows produced by manufacturers with strength and scale.

Five: recognize the quality of installation doors and windows is a three-point product, seven points of installation of things, the installation link is the most important, the quality of installation directly determines the beauty of doors and windows and the convenience of use. It also determines the sealing effect, safety and robustness, etc.

Six: recognize after-sales service has a good after-sales service is a qualified business, can not solve the problem in time and has been delaying the business can not choose.

Look at the profile quality of plastic steel doors and windows. The appearance of the profile should be observed, and attention should be paid to whether the profile color of the frame and the fan that make up the doors and windows is consistent and whether the appearance is uniform. Secondly, look at the clearance and sealing of doors and windows, see whether the matching gap between various profiles is tight, whether the incision at the fit is flat, and the height difference at the lap of the profile.

The quality of hardware also has a certain impact on the life of doors and windows, the hardware used should look thick, and the surface gloss should be good, the protective layer is dense, there is no scratch, the most important point is that the opening should be flexible.

Specifically, it is divided into: 1. Look at the surface quality of the profile.

The quality of the profile can be observed from the surface of the broken bridge aluminum profile, the surface of the good broken bridge aluminum profile is glossy and textured, and the surface spraying color treatment will also be natural, and the look feels smooth; The surface of the broken bridge aluminum doors and windows is rough, there is no luster, and it looks unnatural.

Second, look at the profile section structure.

The geometric angle of the cut surface of the good broken bridge aluminum door and window profile is accurate, and the profile will not be bent and twisted, and the angle is correct. Moreover, the thickness of the cut surface is sufficient, such as the 60 model of broken bridge aluminum doors and windows customized by you, 60 refers to the thickness of the profile is 6 cm, and these 6 cm are full of broken bridge aluminum material, and the proportion of wear strips is small; The less broken bridge aluminum doors and windows will use the 60 profile of the virtual brace, and the thickness will be supported by the strip, and the aluminum material is relatively less.

3. Look at the heat insulation strip of the profile.

Thermal insulation strips are divided into imported and domestic, most of the domestic thermal insulation strips are plastic PVC materials, and imported thermal insulation strips are polyamide, that is, nylon thermal insulation strips. Good quality broken bridge aluminum doors and windows, the use of imported heat insulation strips, its high temperature resistance and low temperature resistance are better, the heat conduction value is low, and it can achieve the effect of heat insulation, environmental protection and energy saving, which can save energy by 20%-30%.

Fourth, a good horse with a good saddle - a good broken bridge aluminum doors and windows must be equipped with good hardware accessories.

The above three points teach you how to distinguish the quality of broken bridge aluminum profiles, so if you really want a good broken bridge aluminum doors and windows, you must match good hardware accessories. As the saying goes, "a good horse with a good saddle", "people rely on clothes and horses rely on the saddle", in order to ensure that the quality of the broken bridge aluminum profile is no problem, the finished products of the broken bridge aluminum doors and windows must be matched well.

5. Gold fittings.

The quality of the accessories determines the flexibility and service life of the doors and windows, and good hardware accessories can ensure that the broken bridge aluminum doors and windows open flexibly, seal intact and will not sink after a long time, and the problem of not closing tightly.

Hello, I personally think that judging a door and window *** is bad, mainly depends on these points:

1. Look at the thickness.

The greater the thickness of the aluminum profile, the higher its firmness does not need to be said, correspondingly, the mute effect of its doors and windows will be better. When you buy, you can test the thickness through the cutting surface of the aluminum profile.

2. Hardware accessories.

Windows and doors need to be opened frequently, so they open easily and smoothly to make people comfortable and noiseless. Fuxuan door and window products make the direction and slide smoothly through the anti-swing positioning wheel, which effectively prevents the door from swinging when pushing and pulling, has stronger wind pressure resistance, and has almost no noise.

3. Tightness.

The well-made aluminum alloy doors and windows are smooth in addition to the splicing of aluminum profiles, and the glass glue must also be smooth. Fuxuan door and window seals are made of EPDM, which is resistant to aging and ensures a long time.

4. Double-glazed glass.

As an important part of silent doors and windows, glass has a great impact on doors and windows. Choose tempered insulating glass with 3C certification, in addition to superior sound and heat insulation performance; In terms of safety, the explosion will not be scratched after shattering.

1.Doors and windows are the two envelope components in the house, and their main functions are for traffic access, separating the connecting building space, ventilation and lighting, etc. The general requirements for inspecting doors and windows are that the installation is flat and firm, no warping and deformation, easy and flexible opening, tight closing, reasonable function, easy maintenance, complete assembly of spare parts, and accurate position.

2.Commonly used door and window materials are wood, steel, aluminum alloy, plastic, glass, etc. Wooden doors and windows are easy to make and suitable for manual processing, which is a form that has been widely used.

Steel doors and windows have high strength, small cross-section, less light blocking, and can be fireproof, and the steel door and window profiles used have been continuously improved to form a variety of specifications and series of products. Ordinary steel doors and windows are easy to rust, have high weight, and have high thermal conductivity. Now the new development of aluminized hollow steel doors and windows, plastic-plated steel doors and windows, color plate steel doors and windows, hollow plastic steel windows have greatly improved the anti-corrosion and energy-saving performance of steel doors and windows, and have been popularized and used in new residences.

3.Aluminum alloy doors and windows are light in quality, tall and exquisite, and have good airtight performance, and have been widely used in houses with high requirements. However, the thermal conductivity of aluminum alloy is large, the insulation is poor and the cost is high.

At present, the use of materials with good insulation properties, such as plastic as the isolation layer made of plastic aluminum windows, can greatly improve the thermal performance of aluminum alloy doors and windows. Plastic doors and windows have good thermal performance, precise processing and corrosion resistance, and are very promising types of doors and windows. At present, the cost of plastic steel doors and windows produced in China is high, and the strength, rigidity and aging resistance need to be improved, but with the development of the plastic industry, the service life of high-strength and aging-resistant plastic doors and windows has reached more than 30 years, and plastic doors and windows will be more and more used.

At present, according to the regulations, the entrance door shall not be made of plywood, the door lock should be installed firmly, and the exterior windows on the ground floor, the public walkway windows on the floor, and the brighteners on the entrance door should be equipped with iron fences; The surface of the door and window glass should be flat, the putty should be full, and the paste should be firm.

The quality of doors and windows mainly depends on the following aspects:

Material: The key to the quality of doors and windows lies in the material, and the performance and performance of doors and windows of different materials are also different. At present, the common door and window materials on the market include wooden doors and windows, aluminum alloy doors and windows, plastic steel doors and windows, broken bridge aluminum doors and windows, etc., consumers can choose the materials that suit them according to their needs and budget.

Observation surface: The surface of doors and windows should be flat and smooth, without obvious scratches and unevenness.

Observation structure: the structure of doors and windows is reasonable, strong and durable, high-quality hardware accessories should be used, and the door leaf should be closely matched with the door frame, without loosening and stuck.

Observation sealing: doors and windows should have good sealing performance, there should be sealing strips between the window sash and the window frame, and there should be windproof, waterproof and soundproof sealing strips between the door leaf and the door frame.

Check the security: The safety of doors and windows is very important, you need to check whether the doors and windows have anti-theft functions, and whether the tempered glass of doors and windows meets the national standards.

Check the manufacturer's information: When consumers buy doors and windows, they can judge the quality of doors and windows by understanding the manufacturer's reputation, scale, after-sales service, etc.

To sum up, the quality of doors and windows can be judged from many aspects such as materials, surface, structure, sealing performance, safety, manufacturer information and other user evaluations.

Method steps.

Look at the profile. You can look at the wall thickness of the profile of the product, the national regulations, the wall thickness can not be lower, the more wind pressure resistance, the stronger the stability, but it is not, the thicker the better, normal home aluminum alloy doors and windows, by the left and right enough. Look at whether the profile is broken, and the broken bridge aluminum has stronger heat insulation and sound insulation performance than ordinary aluminum.

Look at the process. The main processes are the surface treatment process of the profile and the cutting and assembly process. The surface treatment is generally divided into high-grade to low-grade:

Fluorocarbon spraying, coloring electrophoresis, powder coating, ordinary oxidation, wood grain heat transfer, etc. The cutting process is mainly to see whether the corners are flat or not, and whether the opening is smooth.

Look at the glass. Double-layer hollow tempered glass is the best choice, not only has good sound and heat insulation performance, but also has much better safety than ordinary glass. The thicker the glass, the larger the hollow, the stronger the sound insulation.

Look at the appearance. As a part of the decoration of the house, the appearance of doors and windows is also essential. Look at whether the overall design is beautiful, I personally like the feeling of wide vision, you can choose the narrow edge series, the glass is large, and the field of vision is sufficient.

Look at the hardware. Such as pulleys, handles, hinges, hinges, etc. The pulley mainly depends on whether the push and pull are smooth, no noise, no jamming.

The handle mainly depends on the color, style, feel and whether the opening is smooth and barrier-free. It is recommended to choose a hinge with a fall proof and safe. The hardware market is more complex, and it is recommended to choose foreign brands, such as Noto, Willis, Gees, Gewu, etc.

Precautions. The door and window market is complex, and everyone should understand it clearly when buying.

When selecting doors and windows, whether it is profiles or hail glass or hardware, we all know a lot, but in addition to these, when selecting doors and windows, we also need to know what performance of doors and windows?

Wind pressure resistance: The frame material, opening and closing method and glass thickness all affect the wind pressure resistance of doors and windows. Choosing doors and windows with good performance can well ensure the bearing capacity and safety factor of doors and windows in windy conditions.

Water tightness: Considering the water tightness of doors and windows can not only consider the glass of doors and windows, but also consider the selection and installation of door and window adhesive strips. Watertight doors and windows can well avoid the embarrassment of "heavy rain outside the house and light rain inside the house".

Air tightness: the air tightness and water tightness of doors and windows are generally referred to as the sealing of doors and windows, and it is also necessary to pay attention to the glass of doors and windows.

Thermal insulation performance: To avoid the problem of cold in winter and hot in summer, of course, we can not only rely on the sealing of doors and windows, but also look at the thermal insulation performance of doors and windows. The doors and windows of double glazing are better than those of single-glazed windows, and the thermal insulation is especially obvious in winter, and the doors and windows are impermeable, which can well retain the indoor temperature.

Sound insulation: The problem of sound insulation is not only to pay attention to the bedroom, but also to other doors and windows. The sound insulation of the doors and windows is good, which can not only allow you to rest without being disturbed, but also meet your needs for a touch of tranquility in the downtown area.
