Air tightness is a measure of how often air inside a dwelling is changed with air outside through gaps, cialis usa holes and cracks. It is a measure of the performance of a building and essentially refers to the rate of air leakage. It also reflects the energy efficiency of a building, as air that has been warmed using the dwelling’s heating source is being lost and replaced by unwanted colder air from outside. Increasing air tightness through good construction practices reduces air leakage, thus increasing the building’s performance and energy efficiency. Of course, a supply of fresh air is crucial to help prevent damp and to enable occupants to breathe, but a well-designed home built correctly can provide a good and effective level of air permeability.

How is it tested?
All external doors and windows are closed, and all internal doors are opened. A large fan is placed in a suitable opening and turned on, forcing air into the building and pressurizing it. The results of the test reflect the difference between the pressure forced in and the pressure actually recorded within the building.
