A Discourse on the Role that Blower Test Plays for Airtightness

There is always a good reason as to why you need to perform a blower test for airtightness. There are several reasons as to why you would want to establish airtightness. It helps you reduce energy consumption that may be happening because of air leakage. It can also help you avoid problems related to condensation of moisture. This will also help you get rid of the drafts that are really uncomfortable and happen because of either hot or cold air leaking in from the outside.

Saving energy

When air leaks out of an enclosure it means that your home is eating up more energy when the substitute air is being consumed. When you get an airtightness test done you are able to determine the amount of air that your home would leak during cold weather as opposed to warm weather. You would also have a great idea of the difference between the air that would be leaked in windy weather and the similar figure when the weather is on the calmer side.

How long has it been there?

Blower door testing has been in vogue in the United States of America (USA) and Europe from the later part of the 1970s.

Blower Door Test

A blower doors can be described as a strong fan that can be mounted onto an exterior door’s frame. The fan normally pulls the air outside the house and this leads to pressure being lowered inside the room. You should always look for the high performance building supplies when you are building your house or getting it remodeled. It is then that the outside air pressure, which is higher by the way, flows inside your room through the openings and cracks that have not been sealed as of yet. In this case the auditors normally use pencils to detect places from where air is leaking in.

These tests are really helpful when it comes to determining the rate at which air is infiltrating your home. In this case a differential between the pressure inside the building and outside it is measured. The highest permissible figure in this case is supposed to be 50 Pascal.

Identifying holes

With the help of blower door test for testing airtightness you would also be able to know about large holes at your home that you may not have been aware of previously. A blower door test will never show you exactly where the leaks in your house are. But at the same time it will show you that your holes are perhaps much bigger than what you thought them to be. In that case, you would be able to work out for yourself that there are a couple of big holes or more that could be contributing to a lot of air leakage at your home.

The beauty of using top class products

Normally, you would get the best results if the products that you are using at your home have been tested for Window Energy Rating System (WERS). A percentage of this test is supposed to deal with air infiltration.
