Blowerproof
Liquid Membrane

Blowerproof Liquid Membrane is a VOC-free, water-based, flexible, fibre-reinforced, polymer providing a unique and sustainable solution for the production of airtight building connections in both new build and retrofit.

The water-based polymer is brush creates a seamless continuous air and vapour-tight seal around penetrations, and for floor/wall connections, wall/ceiling joints, and roof connections.

The seal perfectly follows the contours of the substrate and in combination with the high flexibility and superior adhesion, the connections remain airtight over the long term.

Blowerproof Liquid is a fast, flexible and durable solution for all airtight connections.

Blowerproof airtight liquid membrane is now BBA certified, used widely across Europe because of its ability to reach unrivalled levels of airtightness. Blowerproof is used to reach Passive Standard 0.6 AC/h in buildings but can reach 0.2 AC/h if required.

• Service penetrations, pipes, cable, ducting etc

• Floor-to-wall junctions

• Ceiling-to-wall junctions

• Window/door jambs

• Steel decks
