The six main properties of aluminum alloy swing door include:
1. Thermal insulation, i.e. K value 2, water tightness 3, air tightness 4, daylighting 5, wind pressure resistance 6, sound insulation and noise reduction
1, What is the K value of doors and windows?
Concept: K value is also called heat transfer coefficient, which used to be called total heat transfer coefficient. The current national standards and specifications are uniformly named heat transfer coefficient. The value of heat transfer coefficient K refers to that under stable heat transfer conditions,
The air temperature difference on both sides of the enclosure is 1 degree (k, ℃). The unit of heat transferred through 1 square meter area within 1 hour is watt / square meter • degree (w / ㎡ • K).
Heat transfer coefficient K of various door and window materials (w / m2 • K)
Ordinary aluminum alloy profile: 6.6 heat insulation aluminum alloy profile: 4.0 wooden window frame: 1.8 5mm white glass: 5.5 (5 12a 5) mm medium blank glass: 2.8 (5 9A 5) mm medium blank glass: 3.0 (5 6A 5) mm medium blank glass: 3.2
Simple calculation method of K value of doors and windows (air tightness is not considered)
In general doors and windows, the area of profile accounts for about 25%, and the area of glass accounts for about 75%. The heat transfer coefficient K of various doors and windows is simply calculated as:
Ordinary aluminum alloy profile doors and windows: k = 6.6 × 25% 2.8 × 75% = 3.75 heat insulation aluminum alloy profile doors and windows: k = 4.0 × 25% 2.8 × 75%=3.10

Uses: Aluminum profile standard connecting angle pieces are mainly used for the right-angle connection of two profiles. They are commonly used connecting angle pieces and have strong supporting capacity. The material is 6063-T5 extruded profiles and the maximum length is 6m. It can be used according to Size cutting is required. There are tapping holes on the side to install the sealing cover; the standard connection angle of aluminum profile is usually used with T-bolts and flange nuts, which can effectively improve assembly efficiency and is very practical;

Broken bridge aluminum alloy window frame is an improved window frame system to improve the thermal insulation performance of traditional aluminum alloy window (non blocking thermal bridge). The principle of broken bridge window is to divide aluminum alloy window into two parts. The inner and outer frames are connected into a whole through the thermal insulation material, so as to block the heat transfer through the aluminum alloy window frame.
According to the connection mode of its inner and outer frames, it can be divided into cast aluminum alloy doors and windows and through strip aluminum alloy doors and windows. The gap between cast aluminum alloy inner and outer windows is filled with polyurethane foam material, while through strip type is to connect the inner and outer frames together after passing through polyamide nylon strips and rolling. The aluminum alloy door and window frame after heat breaking treatment significantly improves the thermal insulation performance on the basis of retaining the good characteristics of high strength and high wind pressure resistance of traditional aluminum alloy doors and windows.
