1. Observe the material].
In terms of material, it is mainly considered from 6 aspects:
1.Thickness: Aluminum alloy doors and windows are divided into several series according to the thickness of the door and window frame, such as the thickness of the door frame structure size is 90mm, it is called 90 series aluminum alloy doors and windows.
In addition, the thickness of the profile also determines the best of the product.
2.Strength: The tensile strength should reach 157 Newtons per square meter and the yield strength should reach 108 Newtons per square millimeter. When purchasing, you can use your hands to bend the profile moderately, and you should be able to restore it after letting go.
3.Chromaticity: The color of the same aluminum alloy profile should be consistent, if the color difference is obvious, it is not suitable to buy.
4.Flatness: Check the surface of the aluminum alloy profile, there should be no dent or bulge.
5.Gloss: Aluminum alloy doors and windows avoid buying profiles with open bubbles (white spots) and ash slag (black spots) on the surface, as well as obvious defects such as cracks, burrs, and peeling.
6.Oxidation: The thickness of the oxide film should reach 10 microns. When purchasing, you can scratch the surface of the profile to see if the oxide film on the surface can be wiped off.
2. Check the sealing performance
Most of the aluminum alloy doors on the market are inlaid with different colors of art glass, these glasses have a single layer, and there are also double-layer insulating glass with a strong three-dimensional effect and good sound insulation effect. When choosing an aluminium door with inlaid glass, especially with insulating glass design, be sure to pay attention to its sealing performance. If the sealing is not good, it will lead to dirt and dirt in the hollow layer, which will affect the appearance.
The brand products are made of high-quality sealing strips and all-round sealing treatment with advanced hot-pressed sealing technology, which can effectively prevent dust and water, and have outstanding sound insulation effects.
Reminder: Check the tightness of the glass compartment of the aluminum alloy door, in addition to checking whether the glass glue coating on the front is tight, but also check whether the sealing strip on the glass on the back of the door is smooth, and no curling and no slotting are required.
3. Observe the processing quality].
High-quality aluminum alloy brand, fine processing, especially some splicing parts are very smooth. The inferior aluminum alloy doors and windows, blindly selected aluminum profile series and specifications, crude processing, door frame corners and other positions can not be spliced and smooth, sometimes even large gaps.
In addition, there should be no obvious damage to the decorative surface of doors and windows, that is, there should be no traces of abrasions and scratches on the surface protective film. There should be no obvious color difference on the tinted surfaces of adjacent components on doors and windows. There should be no aluminum shavings, burrs, oil spots or other stains on the surface of doors and windows, and there should be no spilled adhesive at the assembly joints.
Fourth, check the hardware accessories].
Aluminum alloy doors are mostly installed in humid environments such as bathrooms and kitchens, so the quality of accessories such as pulleys, hardware hinges, door locks, door handles, etc., directly affects the service life of aluminum alloy doors.
Reminder: The quality of the accessories used in the first aluminum alloy doors and windows on the market varies greatly, and the products of regular brands generally use galvanized hinges with high corrosion resistance and not easy to rust, while some small manufacturers will match ordinary iron hinges. Consumers should also carefully identify when purchasing.

Broken bridge aluminum doors and windows are a combination of broken bridge aluminum profile and insulating glass, which is more heat preservation, sound insulation, dustproof, noiseproof, etc., and has better safety performance.
If you choose, you can consider it from the following perspectives:
1. Profile: mainly consider the width and thickness of the profile. The width is generally 60 series, 70 series, 90 series, etc., and the larger the relative value, the better.
In terms of profile thickness, there are, and there are higher, and the national standard standard is. The specific choice depends on the size of the windows in the home, the noise situation in the community, and the personal budget.
2. Glass: float glass, tempered glass, laminated glass, low-e glass, tempered glass is better, used the most, laminated glass and low-e glass can be anti-ultraviolet. In addition, the glass is also available in double and triple layers. Choose according to your needs.
3. Thermal insulation strips: At present, the best ones are PA66 nylon thermal insulation strips, but some businesses use PVC thermal insulation strips in order to reduce costs, and the quality is much worse.
4. Fan hardware: imported and domestic, generally imported lattice house, Siegenia, Noto, etc., as well as German imported hobo (hoppe); The more well-known domestic ones are hopo, top solid, etc.
In any case, there are a lot of roads in the doors and windows, and after determining the specific model parameters, the merchant must write these into the contract so that there is a retention. In case something happens later, it will be clear in the contract and it will be beneficial to you.

1. Sound insulation and noise reduction. The use of insulating glass structure with different thicknesses and the aluminum profile cavity structure of thermal insulation bridge can effectively reduce the resonance effect of sound waves, prevent the transmission of sound, and reduce the noise by more than 30db, even in the downtown area without noise interference.
2. Energy saving and environmental protection. In winter, the window frame with thermal insulation strips can reduce the heat lost through the window frame by 1 3, and in the summer, if there is air conditioning, the window frame with thermal insulation strips can reduce the loss of energy more, which greatly saves the cost of mining and cooling.
3. Prevent condensation. The temperature of the surface of the broken bridge aluminum profile with heat insulation strip is close to the indoor temperature, which reduces the possibility of indoor moisture condensing on the profile surface due to oversaturation.
In short, there are many advantages to choosing broken bridge aluminum profiles for home system doors and windows, and you can give priority to them if necessary.

First, the wall thickness of the profile. The aluminum alloy doors and windows made of aluminum alloy profiles above the national standard have better weather resistance, constant temperature and sound insulation performance, and the service life is relatively longer.
2. Thermal insulation strips. At present, the thermal insulation strips on the market are divided into two types: PA66 nylon strips and PVC, and the thermal insulation ability of PA66 nylon strips is better than that of PVC thermal insulation strips. When distinguishing between PA66 nylon strips and PVC strips, burn the insulation strip with a lighter, and the PA66 nylon strip that can continue to burn after leaving the lighter is the PVC strip that goes out after leaving the lighter.
Third, look at the configuration. Consult the brand, model, hardware, wall thickness, heat insulation strip, sealing strip and whether there are additional charges or losses.

System doors and windows are a perfect organic combination of performance system, need to consider 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, operation feel, etc., but also consider the comprehensive results of the performance of equipment, profiles, accessories, glass, viscose, seals, all of which are indispensable, and finally form a high-performance system doors and windows.
