Collection: Airtight White

Airtight White is Passive Purple's brighter twin — the same liquid-applied airtight, vapour control and smoke tight membrane, in a white that's easy to decorate over and easy on the eye in exposed areas. Passivhaus certified, BBA approved, tested to both ASTM and EN standards (ICC-ES ESR-4715), and a tested radon and methane barrier. Choose the 11.4kg spray/roller pail for big areas, the 6.9kg Home Pack for brush application, or the Brush Pack and Big Boy Bundle for kit-in-one ordering.
