Performance advantages of composite warm edge spacing strips
Release time:
2025-07-17
After using double-layer insulated glass, the edge temperature is 8-12 ℃ higher than traditional aluminum strips in an environment of -20 ℃, significantly reducing condensation.
Thermal insulation performance:
After using double-layer insulated glass, the edge temperature is 8-12 ℃ higher than traditional aluminum strips in an environment of -20 ℃, significantly reducing condensation.
The heat transfer coefficient (U value) of the entire window can be reduced by more than 30%, and when combined with the bridge cut aluminum door and window project, the energy-saving effect can reach more than 5%.
Durability:
The anti-aging test showed that the tensile strength of the material still remained above 85% of the initial value after 2000 hours of accelerated UV aging.
The linear expansion coefficient is similar to that of glass to avoid sealing failure caused by temperature differences.
Security:
Excellent fire resistance, with only 0.15 watts of heat passing through 1 square meter per second when exposed to heat, far lower than the 160 watts of traditional aluminum alloys.
The bending strength has been verified through 15000 cycles of opening and closing tests by Germany's ift, confirming the structural reliability.
