Air Tightness Membranes
Preventing the loss of energy from your home through the elimination of draughts and heat loss, airtight membranes work by enveloping your home in a protective layer that is both economical and functional. These membranes also play a large part in the reduction of structural damage by preventing the onset of condensation, mildew, mould and damp throughout the lifetime of your home. It is imperative that these membranes are sealed using the correct products and that all surfaces are prepared by a professional prior to installation. Once in place, these airtight membranes can help to keep temperatures in your home regulated, eliminate heat loss and increase energy efficiency.

More about Membranes:

Membranes can be vapour-tight, airtight or both and in some instances can be vapour permeable if required. Membranes are primarily used to form an airtight barrier in passive houses and are effective sealant for windows, doors and joints. In order to reach the standard for a passive house, the building needs to be airtight. This airtightness is achieved by in essence sealing the interior of the home with a membrane. In conjunction with the membrane, appropriate adhesive airtight tape needs to be used in order to eliminate any draughts, gaps or air leaks. Avoiding heat loss reduces energy consumption and results in significant savings in utility costs. In order to obtain certification for your passive home, a blower door test will be required to ensure airtightness throughout.
