1.1.2 Seal air leaks located in all cavities present in the building
Description
Air leaks can be located in all cavities present in the building. It is not simple to find all points of air infiltration, which are not limited to doors or windows, so sometimes it can be necessary to carry out the blower door test. In general, typical infiltration points are situated in the joint of two building materials outside and/or inside. Once infiltration points are found, they should be caulked.
Benefits
Reduce heat losses and air infiltration
Easy and fast installation
Improve comfort conditions
Limitations
To obtain the best results, it is necessary to carry out a blower door test
Improving airtightness can lead to more condensation because moist air is trapped in the house
Economic assessment
Low investment. The caulking is inexpensive and easy to carry out. A typical cost of a blower door test ranges from 200€ onwards depending on the size and complexity of the structure. Over 30% in heating and cooling costs could be saved.
