Aerstad® is an energy saving component designed to prevent air flow from the cavity walls passing through the intermittent floor structure and entering the building. By creating an uninterrupted seal at this wall to floor junction we can eliminate uncontrolled air leakage. As a result heat loss through the building envelope is dramatically reduced, lowering building space heating costs and CO2 emissions.
