Structural design of insulation strip
I-shaped
The structure is simple and the cost is low, but the insulation path is short and prone to water accumulation, which is gradually being phased out.
C-shaped
Extending the heat conduction path, improving insulation performance by 30% compared to Type I, with high strength and drainage capability, is the mainstream choice for mid-range doors and windows.
Multi cavity body type
Internally designed with 3 or more independent chambers to block heat convection and radiation, the insulation performance is further improved by 20% -37%, and the compressive strength is ≥ 100MPa, suitable for large glass, high-rise buildings, and high energy-saving demand scenarios.
T-shaped/butterfly shaped
Suitable for special profiles, reducing cold bridges and improving air tightness, used for high-end customized system windows.
