Membranas de barrera contra el radón

Liquid-applied radon protection you can actually see going on. Passive Purple and Airtight White are tested radon and methane barriers, sprayed, rollered or brushed on to form one continuous membrane over floors, walls and junctions — well suited to retrofit, where lifting floors isn't an option. Both are Passivhaus certified and BBA approved, so the same coat that blocks ground gases also delivers your airtightness. Pair with Waterproof Blue liquid DPM and Passivhaus Airtight Sealant to complete the detail.
