• Independently tested to EN standards for performance compliance

Technical Data

Application

EXOPERM DURO 300 Fuse is an external breather membrane designed for use on the cold side of insulation on façade wall and roof applications, providing durable weather protection and vapour permeability for the building envelope.

Suitable for:

• Facades with open or closed joints
• Roof applications
• Ventilated façade systems
• Commercial and residential developments
• Timber and steel framed constructions
• Offsite construction
• New builds and retrofits
• Projects requiring temporary exposure before cladding installation

Triple Layer Fuse Technology

EXOPERM DURO 300 Fuse is a breathable triple layer membrane with a fused functional layer designed for strength, dimensional stability and long term durability.

The fused layer provides enhanced protection for the building envelope:

• Transports vapour to outside
• Maintains high waterproof performance
• Creates a continuous wind tight and weather resistant membrane
• Protects insulation from wind washing
• Provides high resistance to tearing and mechanical damage
• Ensures reliable performance during temporary exposure

Unlike standard membranes, the fused construction provides improved durability and stability, making it suitable for façades, roofs, modular construction and retrofit projects where membranes may remain exposed before final cladding is installed.

Dimensions

• 1.5m X 30m = 45m² (59-1/16” X 98’-5-1/8” = 485 SF)
