The thermal- break, aluminum - profiles are widely used in curtain walls, windows & doors. Most of used thermal - break aluminum profiles are composed of PA66- GF , made of, Nylon and glass fiber, in the middle, forming single cavity, then connected to both sides of aluminum- profile. They have the advantage, of these types of material, at the same time, they meet, the strength, long- life -service -time, and outward color decorated requirements.
There are two methods to make thermal break profiles, one is called injection- type, the other is called insertion- type. The injection- type is replacing the insertion- type with better strength and thermal insulation.
This technology, is introduced to China, from abroad, with social progress and improvements of people-living-standard and upgrading of the living-environment. The single cavity, actually, it is the second cavity, of thermal break profiles, the first and third cavities, are in the aluminum profiles at the both sides. These form 3 dam sealing structure, separating the air channel and water channel, realizing equal pressure in these channels, guaranteeing the excellent air tightness and water tightness for windows & doors and curtain wall.
