Waterproof Breathable Coating

Overview

A fire-rated, breathable waterproof coating designed to protect façades while allowing moisture to escape. Ideal for external surfaces requiring durability, fire safety, and prevention of moisture accumulation.

Key Benefits

• Achieves Fire Class B rating, offering enhanced safety for building façades

• Vapour-open: allows water vapour to diffuse outward, reducing risk of condensation inside wall assemblies

• Waterproof: protects underlying structures from rain, wind-driven moisture, etc.

• Compatible with high-performance insulation systems and fixings (e.g. Rockwool, mechanical anchors)

Typical Applications

• External façades requiring fire safety compliance

• Fibre cement cladding and boards

• Concrete block walls

• Systems with mineral wool or similar robust insulation and mechanical fixings

Performance & Certification

• Certified to relevant fire safety standards (e.g. Fire Class B)

• Supports moisture management in external wall systems

• Documentation available: performance datasheet, lab test reports, installation guidelines
