Efficient air ventilation can only be achieved if the building shell is airtight. In a droughty home, air can flow through cracks. Airtightness prevents air moving out of your home.
We regularly see difficulties self-builders and contractors encounter while trying to make their properties air-tight. Our mission is to provide solutions to these problems.
Wind tightness prevents air moving into the building from outside. Membranes are installed in the external part of the construction, protecting it from cooling and dampness.
