Curtain Wall Foam is a high-density polyurethane (PU) foam material designed for glass curtain wall systems and structural façade sealing applications. The material combines high compression resistance with low compression deformation, allowing it to provide stable structural support while maintaining long-term elasticity.
Its micro-cellular internal structure offers good breathability, which helps accelerate the curing of sealants and adhesives commonly used in curtain wall construction. At the same time, the foam exhibits excellent resistance to heat, humidity, and environmental aging, significantly improving the durability of curtain wall assemblies.
This material is widely used in glass–metal frame connections, joint filling, and façade insulation systems, where stability, sealing performance, and safety are critical.

Curtain wall foam is mainly used in glass curtain wall structures to enhance system stability and sealing performance.
Typical applications include:
Fixing between glass panels and metal frames
Filling curtain wall expansion joints
Providing insulation and acoustic damping
Improving impact resistance and structural safety
Supporting sealant systems
By filling the structural gaps between glass and frame components, the foam helps maintain waterproof performance, reduce vibration transmission, and improve overall façade durability.
