The Airtight White Brush Pack for Small Jobs
Not every airtightness job is a whole house. For snagging, small retrofits and detail-only work, you want a right-sized kit rather than a full drum — without compromising on the quality of the seal.

The problem
Buying large quantities for a small job is wasteful, and running short mid-detail risks an inconsistent seal right where it matters. Self-builders, snagging teams and small contractors need airtightness products in sensible quantities.
The solution: the Airtight White Brush Pack
The Airtight White Brush Pack gives you brush-applied, fibre-reinforced Airtight White in a convenient pack for smaller projects and detailing — BBA and Passivhaus certified, white and paintable.
