Type C Gasket Rigid Substrate Fixing Gasket

Scope of Application

Suitable for fastening TPO/PVC waterproof membranes on rigid substrates such as concrete, cement fiberboard, and gypsum board. Not applicable for glass-magnesium panels or strongly alkaline rigid substrates.

Technical Advantages

• Hollow Reinforced Structure: Provides higher strength, ensuring the gasket remains deformation-free during fastening and under load, thereby offering reliable support

• Recessed Screw Hole Design: Allows the screw head to sit below the surface, effectively preventing abrasion damage to the overlying membrane

• Flat Peripheral Edge: Ensures tight compaction of the membrane and increases friction, significantly enhancing the system's wind uplift resistance
