The relationship between the insulation performance of glass and aluminum alloy doors and windows

Guangdong Galuminium Extrusion Co. Ltd. produces quality Aluminum outside-hung window.
Glass accounts for 75% of the area of doors and windows. The insulation performance of doors and windows depends to the greatest extent on the Kg value of glass. Generally, the Kg value of glass is:
(1) Ordinary single-piece float glass 5mm single-piece glass, U value is only about 5.8 W/m2*K.
(2) Insulating glass: Insulating glass composed of two pieces of float glass passing through spacers, with an air layer with a thermal conductivity of about 0.026W/m·K in the middle, which greatly reduces the heat conduction through the glass, such as 6+12A The U value of +6 insulating glass is only about 2.8 W/m2*K.
(3) Fill the hollow glass air layer with inert gas: Because the inert gas has large molecules and poor fluidity, it can reduce the heat transfer caused by gas convection. Generally, argon filling can reduce the glass U value by about 0.2 W/m2*K compared to air.
(4) LOW-E insulating glass: that is, a transparent low-emissivity film is plated on the side of a piece of insulating glass close to the air layer to reduce the radiant heat transfer and secondary heat transfer from the high temperature area to the low temperature area. The U value of a single piece of LOW-E glass is generally around 3.7 W/m2*K; and when the hollow glass is formed with another piece of ordinary float glass, the U value will be between 1.6-2.0 W/m2*K; if heat insulation is used The performance and effect of double silver Low-e glass is better, and the heat insulation effect can reach 1.5 W/m2*K; on this basis, it can be filled with inert gas to reach 1.3 W/m2*K.
Aluminum alloy doors and windows are a collection. Through reasonable craftsmanship and professional equipment, profiles, hardware, glass, components, etc. are organically combined according to standardized requirements to meet the needs of building ventilation and lighting. To meet these requirements, it must have basic wind pressure resistance, watertightness, and airtightness. With the improvement of people's living standards, higher requirements are put forward on doors and windows, such as sound insulation, heat preservation, sunshading, and safety. The quality of doors and windows must be grasped from the source. Advanced structural design and high-quality and stable component quality are the foundation. Combining scientific processing technology and well-trained processing and installation workers can ensure the quality of doors and windows. The appearance and opening method of doors and windows have not changed much, and there is no high technical content. All of its contents are in the rigor of the assembly process and the coordination of each component. Aluminum outside-hung window is your good choice.
