Air Sealing

Air Sealing

As part of the sustainable requirements for new buildings, air sealing or air tightness testing not only aids the energy efficiency of a building but also assists in the operation of the building's heating and ventilation systems.

SDH Services use a range of insulation products that will provide the relevant seal between the internal and external perimeters of the building.
