Product Overview
Easy Trim Master Breather Membrane in a 50m x 1m roll, providing 50m² of coverage, designed as a high-performance breathable underlay for pitched roofs and timber frame walls.
This advanced membrane delivers dual functionality: it prevents external water ingress while allowing internal moisture vapour to escape. By maintaining this critical balance, the membrane safeguards roof structures from condensation-related damage, including timber decay, insulation deterioration, and mould growth.
Suitable for use in warm, cold, and hybrid roof constructions, it performs consistently in both fully supported (direct to sheathing boards) and unsupported (draped between rafters) applications.
Its 1m width makes it especially suitable for smaller projects, confined spaces, and precise installations, offering easier handling where manoeuvrability is limited.
The membrane is engineered to withstand all five wind zones defined by BS5534:2014 Annex A, meaning it can be confidently specified for both sheltered inland properties and exposed coastal or high-altitude locations.
Features & Benefits
- Superior bond strength: Enhanced durability ensures reliable long-term weather protection.
- UV stability: Withstands UV exposure for up to 3 months during construction.
- Improved thermal efficiency: Reduces air penetration to enhance insulation performance and limit energy loss.
- Versatile installation: Performs effectively in both fully supported and unsupported installations.
- Roof compatibility: Suitable for warm, cold, and hybrid roof systems.
- Wind zone compliant: Certified for wind zones 1–5 under BS5534:2014 Annex A.
- BBA certified: Independent verification of quality and performance.
- Lightweight handling: Flexible design makes installation faster and easier on site.
- Easy handling: 1m width is simple to transport and install, even in restricted spaces.
Applications
- Tiled and slated pitched roofs: Provides a weather-resistant breathable underlay.
- Warm, cold, and hybrid roofs: Compatible with multiple roof configurations.
- Timber frame walls: Functions as a breathable sheathing membrane.
- Fully supported and unsupported installations: Direct to boards or draped between rafters.
- Exposed locations: Suitable for all UK wind zones, including coastal and high-altitude sites.
Installation Guidance
- Substrate preparation: Ensure surfaces are clean and dry before application.
- Fixing: Secure using corrosion-resistant staples, nails, or fixing tapes as appropriate.
- Laps: Overlap horizontal joints by at least 100mm (or more in high wind zones).
- Drape: In unsupported installations, allow sufficient drape between rafters to channel moisture.
- UV exposure: Cover within 3 months to protect from long-term degradation.
- Compatibility: Always install with reference to BS5534:2014 and manufacturer’s guidance.
Compliance & Performance
