There are two main ways to produce heat-insulating profiles, one is to use heat-insulating strip material and aluminum profiles, through mechanical open teeth. Threading, rolling and other processes to form [heat insulation bridge], called heat insulation profiles [threading type], the other is the heat insulation material is poured into the heat insulation cavity of aluminum alloy profiles, after curing, removal of bridge-breaking metal and other processes to form [heat insulation bridge], called [pouring type] heat insulation profiles, aluminum alloy profiles on the ultraviolet, visible light, infrared has a very good reflective ability.

The reflective ability of its surface is related to the surface state and color, the reflective ability of thermal radiation can reach 90%, which is very beneficial to block the solar radiation heat, but the thermal conductivity of aluminum alloy is very high, and is not conducive to energy saving, the internal and external surfaces of the thermal insulation profiles, can be a different cross-section of profiles, and can also be a different surface treatment of different colors of the profiles.

But by the region, the climate, to avoid due to the difference between the line coefficient of the thermal insulation material and aluminum profile is very large, in the cold contraction between the two produce large stress and gap, at the same time, the thermal insulation material and aluminum profile combined into.

Both adhere to the savings, but also the development of new new materials, take a low energy consumption across the road of development, the construction of a conservation-oriented society, we are actively studying the thermal insulation of doors and windows thermal insulation bars at the same time, we must recognize the development of high new materials is an important foundation for building energy efficiency, only materials with excellent performance, in order to ensure that the protection of the project's long-lasting heat preservation and insulation performance.
