Air Leakage

Products designed to tackle heat and air leakage enabling house builders to achieve the targets for modern, energy efficient homes.

Builders face constant pressure to make their houses energy efficient, and buildings that fail to meet air leakage standards can cost thousands of pounds in wasted time and repeat labour. Heat loss due to air leakage can also lead to mounting energy bills and a drafty, uncomfortable home for the eventual occupant.

Manthorpe’s range of joist sealsradiator pipe guide and seals air leakage products are designed to tackle these problems quickly and effectively making it easier for the builder on site to deliver a quality home.
