Draught proofing plays a crucial role in reducing heat loss and lowering heating bills by minimizing air infiltration through gaps in buildings, especially around windows and doors. Buildings constructed between 1900 and 1990 typically experience air permeability rates of 20-30 cubic meters per hour per square meter of floor area due to poor sealing. This issue arises from natural leakage through the building’s fabric and gaps around windows and doors. Effective draught proofing can reduce this rate to 10-15 cubic meters per hour, providing a low-cost solution to cut heating costs. Advantages of Draught Proofing: Draught proofing can reduce heating bills by around 8-10 per year per window or door.
