Blowerproof airtight coatings, with BBA and Passive House approval.

In 2011, airtight methods went trough a revolution with the launch of our Blowerproof® airtight paint. This simplified method for airtightness fitted perfectly with the increasing demand for green buildings. Since, the quality of Blowerproof® has been unrivalled and holds various international certifications such as Passive House, BBA, Exova and M1. Due to its high density, Blowerproof may also serve as methane, radon or intelligent vapour barrier.
