Waterproof Breathable Membrane T120

T120 Waterproof Breathable Membrane: High-Performance Building Protection

The Waterproof Breathable Membrane T120 is a high-performance, multi-layer construction membrane. It is engineered to provide robust weather protection while allowing water vapor to escape from the building structure. This balance is critical for managing condensation in roof and wall assemblies, a primary concern for construction professionals. Its design supports the long-term durability and energy efficiency of commercial and industrial buildings.

Performance Advantages

• Simultaneous Waterproofing and Vapor Permeability: Creates a weather-resistant barrier that also reduces the risk of interstitial condensation.
• High Tensile and Tear Strength: Provides durability during and after installation, resisting damage from wind and handling.
• UV Resistance: Withstands prolonged exposure to sunlight during construction phases.
• Temperature Tolerance: Maintains performance across a wide range of climatic conditions.

Application Areas

The T120 membrane is specified for use in:

• Ventilated rainscreen facades and cladding systems.
• Pitched roof applications beneath tiles, slates, and metal roofing.
• Timber frame construction as a weather-resistant barrier.
• Commercial and industrial building envelopes requiring robust moisture management. Its properties make it a key component for improving energy efficiency in commercial buildings by protecting insulation performance.

Frequently Asked Questions (FAQ)

What is the typical lifespan of the T120 membrane once installed?

The membrane is designed to last the lifetime of the building envelope when installed correctly and protected from direct long-term UV exposure by the final cladding or roofing material.

Is the T120 membrane suitable for use in cold storage facilities?

Yes, its low temperature tolerance and high vapor permeability make it applicable for cold storage buildings where managing significant vapor drive is a critical design requirement.

Can this membrane be installed in contact with EPS (expanded polystyrene) insulation?

Yes, the T120 membrane is chemically compatible with common insulation materials, including EPS, XPS, and mineral wool.
