Breathable Waterproof Membrane
PP+PE Complex Material for Building Roof and Wall
The Breathable Waterproof Membrane T260 is a three-layer composite material combining nonwoven fabric and PE film, engineered for roof and wall applications where vapour permeability and liquid water resistance are required. With an SD value of 0.02±0.015, the membrane allows controlled moisture vapour transmission while maintaining a water penetration resistance class of W1. The material has a mass per unit area of approximately 260 g/m², providing a balance of mechanical strength and handling flexibility. Tensile strength is specified at MD 280±40 N/50mm and CD 200±40 N/50mm, with elongation values of MD 80±80 N/50mm and CD 80±65 N/50mm, indicating a defined stretch capacity under load. The membrane offers UV resistance for 3 months and is available in standard roll dimensions of 1.5 x 50 m, with custom sizing and color options upon request. This product is suitable for use as an underlay or breather membrane in pitched roofs, timber-frame walls, and other building envelope systems.

Core Advantages
- Three-layer construction (nonwoven + PE film) provides a durable composite that resists delamination under typical handling and installation stress.
- SD value of 0.02±0.015 enables controlled vapour permeability, reducing condensation risk while maintaining a water-tight barrier (W1).
- Tensile strength (MD 280±40 N/50mm, CD 200±40 N/50mm) and elongation characteristics (MD 80±80, CD 80±65) offer defined mechanical performance for roof and wall substrates.
- UV resistance for 3 months allows for exposed installation periods during phased construction, with custom color and dimension options for project-specific requirements.
Application Scenarios
- As a breather membrane under roof tiles, slates, or metal roofing, allowing vapour to escape while resisting liquid water ingress.
- For use in timber-frame, steel-frame, or masonry wall systems as a weather-resistant barrier behind cladding.
- In cold or mixed climates where vapour control and drainage are critical for the durability of the building envelope.
- Suitable for new construction, refurbishment, and retrofit projects that require a breathable yet waterproof underlay.

Frequently Asked Questions
expand all What does the SD value 0.02 indicate for this membrane?
The SD value (0.02±0.015) represents the water vapour diffusion resistance of the membrane. A lower SD value indicates higher vapour permeability, allowing moisture from the building interior to escape through the membrane, reducing the risk of condensation in roof and wall assemblies.
Can this membrane be used as a temporary roof covering?
While the membrane offers UV resistance for 3 months and can withstand short-term exposure during construction, it is designed primarily as an underlay beneath permanent roof or wall coverings. For extended temporary covering, additional protection or alternative products may be more suitable.
What is the difference between W1 and other water penetration classes?
Class W1 indicates that the membrane has passed a water penetration test at a defined hydrostatic pressure, confirming its ability to resist liquid water ingress under typical roof and wall conditions. Higher classes (W2, W3) correspond to higher pressure resistance, while W1 is commonly specified for standard breather membrane applications.
Are custom colors and dimensions available for this product?
Yes. Custom dimensions and colors can be arranged on request. Lead times and minimum order quantities may apply depending on the specific requirements. Please contact the supplier for detailed customization options.
