Doors and windows are indispensable in life. Many people regard this industry as a bonus industry, and countless people join it. Here comes the question. Do you know that the doors and windows you joined are really up to standard? What is the quality of doors and windows? There are certain specifications and standards in the door and window industry. Do you know all these? If you don't know, today, Paiya doors and windows will share with you the five quality standards of doors and windows. You can compare and see if the brands you join meet the standards.
The quality standard of doors and windows is mainly calculated from five aspects: sealing performance, leakage prevention performance, frame fan structure, thermal insulation performance and safety technology.
I. Sealing
1. Corner sealing strip (rubber angle): the sealing strip should avoid corner splicing, and the corner sealing strip should be designed as a 90-degree integral rubber angle.
2. Frame fan sealing strip: Three sealing strips should be designed for opening the fan, which are mainly sealing strip, fan edge pressing strip and frame edge pressing strip respectively.

II. Anti-leakage performance
1. The outer window must be equipped with drainage channel, drainage outlet and exhaust hole (air pressure balance hole) to drain the water in the window frame. Buckle cover should be set outside the outfall to prevent strong wind from blowing rain and dust into the Casement.
2. The heat insulation strip should adopt C- type structure, which is on the same horizontal plane after being combined with internal and external aluminum profiles to avoid leakage and corrosion hazards caused by water accumulation at the heat insulation strip. At the same time, the length of the heat insulation strip can be increased to improve thermal performance.
3. Door and window opening size: the structural opening should not be reserved too large to avoid leakage hidden danger caused by plugging difficulties.
4. Gate: for special reasons, if the external wall is stone curtain wall, the reserved size of the gate is large. It is recommended to make a gate for the structural Gate. The gate should be poured at the same time as the concrete wall.
5. Exterior sill plate: metal sill plate is recommended for buildings with exterior wall materials as coatings. The inside of the metal sill plate should be pressed into the window frame, and the outside should highlight the wall for dripping water.
6. Window frame and structural opening: The window frame should be installed in the vertical. If it is installed by the outside, it should be folded inward by 20mm to prevent the window frame from being installed outside the outer skin of the structure due to structural construction errors, resulting in rainwater leakage.

3. Frame fan structure
1. Set angle: set angle is an important process related to the integrity of doors and windows.
2. Glue-wiping process: Generally, the angle code glue-wiping process should be adopted. Corner of the window extrusion molding without glue-wiping is prohibited.
3. Glue injection process: the corner group can also adopt the angle code conductive glue groove glue injection hole two-component glue injection antler slices process to ensure the strength requirements of the corner and ensure that the finished products of doors and windows do not have the phenomenon of deformation and displacement after transportation and installation.

IV. Thermal insulation performance
1. Cavity design of profiles: profiles should adopt multi-cavity structure to reduce heat loss. At the same time, external window insulation components should be coplanar up and down to form an integral insulation surface to eliminate cold bridges, block heat loss channels.
2. Heat insulation strip should be installed in the glass installation tank: increase the number of air chambers, reduce the heat loss between the hollow glass and the profile, and improve the heat insulation effect of the whole window.
3. Casement should adopt T-type heat insulation strip design: Casement the heat insulation strip is designed as T-type, overlapping with the middle adhesive strip to realize the hot and cold partition at the joint of the fan frame. It is forbidden to place the middle rubber strip directly on the aluminum profile of the fan.
4. The heat insulation strip should adopt polyamide 66 (I .e. Polyamide66, commonly known as Nylon 66).
5. Glass warm Regula: double glazing unit warm Regula should be set around the cavity to block the cooling channel of the glass cavity.
6. In areas with high heat transfer coefficient requirements, according to the project positioning, the heat insulation heat barrier material can be added to the heat insulation cavity of the profile to meet the k value requirements.
7. Exterior door: the threshold should be set for the exterior vertical hinged door of the first floor of the residence leading to the garden. No threshold should be set, and the bottom of the door should be closed with a brush. The first floor residents of the house open double doors to the garden flat. After closing, the two doors should be bite and lap, and it is forbidden to leave a seam in the middle and close it with a brush.

v. Security technology
1. Glass buckle: The glass buckle should be installed on the indoor side. It is forbidden to turn the in-swinging casement window into outwards opening window so that the buckle is installed on the outdoor side to ensure the requirements of anti-theft, safety and glass replacement, leaving no leakage hidden danger.
2. Lock point: in order to improve the wind pressure resistance and anti-theft performance of the outer window, the outer window should adopt multi-point lock. The lock point setting shall meet the requirements of hardware manufacturer's design and installation manual.
3. The outer door size of the unit entrance should not be too large to ensure the reliability of hardware accessories such as hinge and avoid safety accidents. Whether you are selecting doors and windows to join the brand, or choosing doors and windows for your own home, you can follow the above 5 top ten brands of doors and windows compare the quality standards to see if the doors and windows you choose meet the requirements. Don't make a comparison because it is too troublesome, and then regardless of the random choice or listening to others' opinions, at that time, the doors and windows are not up to standard, and the damage is also yourself.
Whether you choose which brand of doors and windows to join, or choose the doors and windows used in your own home, you can follow the above five major top ten brands of doors and windows compare the quality standards to see if the doors and windows you choose meet the requirements. Don't be too troublesome, and then don't care about random choices, or listen to others' opinions, etc, if you do not make a comparison when choosing doors and windows, the doors and windows will not reach the standard at the end, which will cause harm to yourself.
The above is the quality standard requirements of doors and windows, and the content is for your reference only!
