Breather Membrane – Flame-Retardant – Exterior Building Applications

Product Overview

This 1.5m x 50m flame-retardant breather membrane is designed to self-extinguish when exposed to flame, providing superior safety for building envelopes. It features a halogen-free coating that reduces smoke and droplet formation while ensuring minimal environmental impact. Offering the same airtight, watertight, and vapour-open characteristics as standard systems, it enhances flame-retardant performance for safer construction projects.

Features & Benefits

• Self-extinguishing behaviour: Utilizes advanced technology to limit flame spread and enhance façade safety.
• Halogen-free coating: Offers reduced smoke and droplet formation for lower environmental impact.
• Breathable construction: Ensures moisture vapour diffusion while preventing rain ingress for stable wall conditions.
• Wind and weather protection: Provides airtightness and water resistance for optimal energy performance.
• High fire performance rating: Achieves a B-s1,d0 classification, indicating very limited fire growth contribution.
• Lightweight handling: Facilitates easy installation over large areas without compromising durability.
• Long-term reliability: Consistently protects various construction types, including residential and commercial buildings.

Applications

• High-rise façades: Suitable for tall buildings requiring flame-retardant weather protection.
• Ventilated façades: Acts as a vapour-open barrier behind cladding systems.
• Timber frame walls: Supports fire safety and controlled drying within lightweight assemblies.
• Commercial and residential envelopes: Provides durable weather protection and controlled vapour movement.
