Colección: Membrana impermeable

Weatherproofing that goes on wet and stays put. Passive Purple External is our airtight, fire rated (Class B) façade waterproofing membrane, sprayed, rollered or brushed over sheathing boards and masonry to keep the weather out while the build catches up. Passivhaus Brickseal protects finished masonry as a weatherproof damp proofing paint, and Passive Purple X (also Class B) covers the internal-to-external details. Available in purple, white, black and cream — one continuous coat, no laps, nothing flapping in the wind.
