Product Overview
Actis Boost'R Hybrid Reflective Breather Membrane with a 35mm thickness and 10.05m² roll area is a dual-function insulating and breathable membrane designed to enhance thermal performance while maintaining controlled vapour movement. Its multi-layer reflective structure reduces heat loss through radiation and convection, contributing to improved overall envelope efficiency.
The membrane provides water resistance and windtightness on the cold side of the insulation while allowing internal moisture vapour to diffuse outward, protecting structural elements from trapped humidity.
Its integrated insulation layer supports reduced thermal bridging across rafters and studs, offering dependable performance in roofs and walls where space efficiency is required.
Lightweight and flexible, it adapts easily to uneven surfaces and complex detailing, ensuring consistent coverage in both refurbishment and new build applications.
The membrane is suitable for use behind ventilated cladding or roof coverings, forming a protective, high-performance layer that complements hybrid insulation systems.
Features & Benefits
- Reflective thermal performance: Reduces radiative heat transfer to enhance overall thermal efficiency in roofs and walls.
- Breathable construction: Allows controlled vapour diffusion to limit condensation risk within the building fabric.
- Windtight and water resistant: Protects the structure from wind-driven moisture while maintaining stable internal conditions.
- Integrated insulation layer: Provides additional thermal resistance and reduces cold bridging across framing elements.
- Lightweight handling: Enables quick, accurate installation on uneven or complex surfaces.
- Versatile compatibility: Suitable for use with hybrid insulation build-ups and common timber or metal framing systems.
Applications
- Pitched roofs: Provides a reflective, breathable external layer to enhance thermal performance and moisture control.
- Timber frame walls: Supports hybrid insulation arrangements requiring improved thermal resistance with vapour permeability.
- Refurbishment projects: Offers space-efficient thermal enhancement where traditional insulation depth is restricted.
Installation Guidance
- Substrate preparation: Ensure framing, insulation, and sheathing surfaces are clean and suitable for continuous membrane coverage.
- Membrane alignment: Unroll the membrane with the reflective surface correctly oriented to achieve declared thermal performance.
- Fixing application: Secure using appropriate staples, battens, or tapes without overstretching the material.
- Lap detailing: Maintain consistent overlaps and seal where required to preserve windtightness and moisture protection.
- Penetration sealing: Use compatible accessories around openings and service routes to maintain continuous thermal and moisture control.
Compliance & Performance
- Material specification: Manufactured as a multi-layer reflective membrane incorporating a 35mm insulating core.
- Thermal behaviour: Designed to reduce radiative heat loss and enhance U-value performance within hybrid systems.
- Moisture management: Functions as a breathable yet water-resistant layer for stable building enclosure conditions.
- Important note: Always install according to manufacturer guidance to maintain declared thermal, moisture, and windtightness performance.
