Breather Membrane – Housewrap – Residential & Commercial Use

Product Overview

The High-Performance Housewrap Breather Membrane, measuring 1.4m in width and 100m in length, is engineered to provide exceptional weather protection for timber, steel, and concrete wall systems. Its lightweight, vapour-permeable design effectively resists wind and water, while enabling controlled moisture movement.

This membrane enhances building envelope performance by regulating heat, air, and vapour transfer, ensuring stable internal conditions for new builds, refurbishments, and extensions. It is designed for external surface application, attaching directly to sheathing boards, insulation layers, or masonry substrates, forming a reliable protective layer beneath cladding.

Features & Benefits

• Breathable Construction: Allows internal moisture vapour to escape, reducing condensation risk and maintaining stable wall conditions.
• Wind-Tight & Water Resistant: Offers durable external protection, preventing wind-driven rain ingress while maintaining structural dryness.
• Energy Efficiency Support: Optimizes thermal performance by limiting air leakage and stabilizing internal temperatures year-round.
• Durable Polyethylene Structure: Composed of high-density fibres for long-term resistance against external weather loads.
• Lightweight Handling: Simplifies installation across large elevations without compromising membrane integrity.
• Extended Exposure Tolerance: Can remain uncovered for up to four months while retaining full declared performance.
• Certified Performance: CE marked and approved by BBA, IAB, and UKAS for compliance across building types.

Applications

• Timber Frame Walls: Provides a vapour-permeable, wind-tight layer suitable for lightweight structural assemblies.
• Steel Frame Structures: Supports controlled moisture behaviour and weather protection in metal-stud construction.
• Concrete Walls: Acts as an external breather membrane to regulate vapour movement and enhance façade durability.

Installation Guidance

• Substrate Preparation: Ensure sheathing, insulation, or blockwork surfaces are clean, level, and securely fixed before installing the membrane.

FAQs
