There are several types of material as door frames，the time trend is from timber, steel, aluminum and UPVC. The thermal insulation aluminum profiles invented is a big change to aluminum door frames. It has a huge impact to the door frames material trend. The thermal break aluminum profiles used as doors frames are widely used in the whole world now.
The thermal break part in thermal insulation aluminum profiles is PA66 nylon glass fiber. It helps the thermal insulation aluminum profiles to form 3 cavities in the section. The first cavity in thermal break aluminum profile is used as waterproof, the second cavity, it is the PA66 cavity, used as thermal insulation part in the thermal break aluminum profile, solve the cold bridge problems in the aluminum profiles. The third cavity is also the last part, normally used in the indoor side, its function is keeping the air tightness. They are the reasons why thermal break aluminum windows and doors have better airtightness, water tightness, and U – values. They are also the reasons why the thermal break aluminum profiles for windows and doors are widely used around the world.
There are two methods to do the PA66 nylon glass fiber in the thermal break aluminum profiles. They are insertion and injection. The injection PA66 can get more strength than the insertion, 4 times in shearing resistance, 1.25 times in thermal insulation performance. The insertion to do the PA66 for thermal break aluminum profile is slowly disappearing in the world, replaced by the injection.
