What is a thermal break strip?
Thermal break strip, also called heat insulation strip, is a part of aluminum bridge profile. The heat-insulating bridge aluminum-plastic profile can realize the three-way sealing structure of doors and windows, and reasonably separate the water vapor chamber. It successfully realizes the pressure equalization of gas and water, and significantly improves the watertightness and airtightness of the doors and windows.
Adding a thermal break to a window or door prevents both heat and cold from transferring through the frames altogether, alleviating issues that might be caused by extreme environments. By controlling this transfer, thermally broken windows and doors improve energy efficiency.
According to different storage time and ambient climate, the dimension of PA strips will increase slightly because of the natural moisture absorption. And the mechanical properties will change slightly too.
So, PA strips should be transported and stored under dry conditions away from the influence of weather. (rain, direct sunlight etc.)
They provide a better thermal insulation
They need lesser use of metals
The polyamide strips are cost-effective
They are easy to create thermal barriers with
They help in resources to be conservedand can reduce operating costs
They ensure maximum stability of the structure
They are more than effective in resisting condensation
They don’t require any special handling or fabrication
It is mainly used in insulation broken bridge aluminium products, helping to reduce heat loss or heat gain through the aluminum, and has better performance in terms of power usage.
