Similar to firestopping, acoustic sealing is required where sound can penetrate from one building compartment to another. Increasingly important in schools, hospitals, offices and dwellings where noise transfer is a nuisance. Dense insulating products are installed to limit the travel of sound where compartments are breached. Typically these areas include service penetrations through walls, floors and perimeter edge details.
Spiralling energy costs and environmental focuses including BREAM have driven the need for modern buildings to be effectively sealed to prevent the escape of air and, more importantly, heat.
The perimeter of the structure where the different construction elements meet is the most likely are for leaks. It is vital that these areas are sealed effectively as air test requirements are becoming more onerous.
