Installing an airtight membrane is an excellent method of preventing heat loss. As the name suggests, it involves installing a membrane over the insulation that has been installed; thus, preventing drafts from entering the structure.All joints and gaps are sealed using a specialist tape.
A well-installed airtight layer reduces unwanted draughts and air loss. This in turn reduces the amount of air you need to heat your property, which in turn saves energy. This also helps greatly with ventilation and humidity. Airtight membrane is a must in any new construct.
