Blowerproof’s paint and spray-on liquid airtightness products have become increasingly popular in the low energy building and retrofit markets in recent years, with the product being specified on an increasing number of passive house projects, and becoming highly regarded for its ability to air-seal tricky details and junctions.

“I am delighted we have obtained this certification, said Herman Van Damme of Blowerproof manufacturer Hevadex. “The rigorous testing it’s put through by the [Passive House] Institute really proves the superior performance of Blowerproof for use in passive buildings and is recognised by designers as a certification they can rely on. It helps make everyone more comfortable about specifying and using Blowerproof.”

Blowerproof have also announced a significant update to their BBA certificate. The update means that Blowerproof liquid version is now certified for use as a radon barrier, and for dot-anddab applications behind internal plasterboard. It also now has a Class C-s1 fire rating.

“Blowerproof have moved to strengthen their position in the market by improving their certification and accreditation in light of increasing specification and demand in the market,” Will Kirkman of Blowerproof UK told Passive House Plus. “We are seeing the product being specified more and more given the push towards net zero carbon buildings and with changes on the way to Part L and F of the building regulations.”
