Exoperm Duro 300 Fuse Breather Membrane is a high-performance breathable triple layer membrane designed for façade and roof applications in modern construction projects. Developed using advanced fused construction technology, this durable breather membrane provides reliable weather protection, high vapour permeability and long-term performance for external wall and roofing systems. Engineered to withstand harsh weather and extended UV exposure, it maintains excellent dimensional stability
This advanced breather membrane pairs superior tear resistance with high vapour permeability. It ensures airtight and watertight integrity while letting buildings breathe. Its rugged construction allows for extended temporary exposure, making it ideal for new builds, retrofits, and offsite modular construction.
Featuring W1 water resistance, it shields structures against wind and heavy rain. The vapour-open design prevents condensation, lowers moisture-damage risks, and fosters healthy indoor environments. Exoperm Duro 300 Fuse provides a secure envelope solution that extends building lifespan and structural performance.
