What is Air Tightness Testing?

Air Tightness Testing is used to identify the areas that cause the drafts that blow over your shoulder when sitting by the fire. These drafts contribute considerably to heat loss in your home and therefore increase your heating cost and reduce your comfort. A standard house has an air tightness test result of between 7 to 10 Air changes per hour. This means that on a windy day the air in your house changes from warm air to cold air up to 10 times in 1 hour. This means that you have to heat the air 10 times in one hour. In other words if your air change rate was 1, you heat the air up to comfortable temperature once every hour and it will take 1 hour for that warm air to be replaced with cold air.

In a typical house air needs to be reheated every 6 minutes. In an airtight house, air only needs to be heated every 60 minutes
