Air Tightness

Air leakage increases the amount of heat loss as warm air is displaced by colder air from outside. This colder air then needs to be heated. The more airtight your house the less air changes per hour and therefore the less you will spend heating it.

High levels of air tightness in homes will become an integral part of construction within future regulations. 

Hometherm are approved installers of the SIGA Air Tightness system. The SIGA system consists of a range of vapour membranes tapes and adhesives to seal your home.

SIGA Air Tightness System

If a building is made airtight does that not go against normal requirements of having a certain amount of natural ventilation?

Air tightness is commonly used in conjunction with a Heat Recovery Ventilation System. This constantly introduces fresh, clean air into the home from the outside while expelling stale and moist air from parts of the home such as bathrooms, kitchens, etc.

At what stage of constructions do Hometherm undertake Air Tightness works?

Hometherm undertake Airtightness once the following is complete;

Windows and Doors installed.
Window reveals to be finished to window frame with sand and cement.
Window boards should NOT be in place.
