Air tightness
Heat loss for cold draughts accounts for 15% of the total heat loss in a home.
Throughout the year, but especially in winter, people start to notice air leaks. Most people call these leaks, draughts. Air leakage in a home is a major contributor to heat loss as cold air is sucked into the home around door/window frames, skirting boards and attic doors.
Process:
Air leaks can be located using blower doors or thermal imaging. Firstly, all of the vents and chimneys in the building are sealed. Then, a fan is mounted onto an external door and the house is pressurised with air. Software then calculates how 'leaky' the building is. This is equated as air changes per hour.
Sealing draughts
The leaks are then located using smoke matches and thermal imaging. The draughts can then be stopped using polystyrene expanding foam, silicone sealant & draught strips. The house is then re-pressurised and the before and after reading can be compared.
Results
Cutting down air leaks from a building not only improves the efficiency but will vastly improve the comfort levels of your home. If you are also carrying out a building energy rating (BER), the new air change value can be entered into the system to give an improvement on the BER.
