Airtightness Detailing Pack For Smaller Projects — Intelligent Membranes

The Airtightness Detailing Pack for Smaller Projects

Not every airtightness job is a whole development. For self-builders, snagging and detail-only work, you want a right-sized pack that covers the junctions and penetrations without buying in bulk.

Detailing the airtight layer

Why detailing is where it counts

Air leaks at junctions, penetrations and reveals, not across open plaster. On a smaller project, getting these details sealed is what moves the air-test result — so a focused detailing pack often matters more than drums of membrane.

The solution: the Passive Purple Brush Home Pack

The Passive Purple Brush Home Pack gives you fibre-reinforced, brush-applied Passive Purple in a convenient pack — ideal for self-builders detailing junctions, penetrations and reveals to a Passivhaus-grade standard.
