C Shape 18mm Dust-Proof Firm Polyamide66 Heat Insulation Bridge for Broken Bridge Aluminum Profile Window and Door Material
Product Introduction
Insulation of aluminum doors and windows sealed with insulation strip is the one with the glass fiber reinforced polyamide nylon (PA66), referred to as Nylon 66 insulation strips, expansion coefficient is small, heat-resistant, and anti-aging properties.
Broken Bridge aluminum thermal break strip is an important criterion for distinguishing aluminum alloy doors and windows and broken bridge aluminum doors and windows.It is precisely because of the appearance of broken aluminum thermal break strips that the aluminum doors and windows of the broken bridge have good thermal insulation and sound insulation performance. The extruding high precision polyamide thermal break strip is used in windows and doors.Inserted in the thermal break aluminum profiles,it is the part of energy-saving window system for reducing heat sonduction.
Why do you need a thermal break?
Why are thermal breaks important? Thermal breaks are essential for any external modern glazing system. Thermal bridging can be responsible for up to 30% of a property's heat loss. This lowers the homes energy efficiency, leading to higher heating bills.
Product Advantage:
1.Effectively increased thermal in the system property insulation.
2.Reduces condensation on the window.
3.Sound insulated.
4.Improve comfort and living condition.
5.Possible double color coatings provide better aesthetic effect.
6.Various shapes will be designed for the customer's requirements.
7.The working temperature of the thermal insulation strip is 220°C, Melting Point reaches to 246°C. This enables coating process after assembly of composite profiles.
8.High corrosion-resistance, weather-resistance, heat-resistance, alkali-resistance and long life of usage.
9.Linear thermal dilation coefficient almost identical to that of aluminium profiles.
