Blower Door Test Measurement

A blower door test is used on buildings in order to quantify the amount of air leakage through its enclosure.

Blower door test measurement.

There are two types of blower doors. It can also be used to measure airflow between building zones to test ductwork airtightness and to help physically locate air leakage sites in the building envelope. It can also be used to measure airflow between building zones to test ductwork airtightness and to help physically locate air leakage sites in the building envelope. Cfm50 is the airflow measured in cubic feet per minute from the blower door fan needed to create a change in building pressure of 50 pascals.

A blower door is a machine used to measure the airtightness of buildings. We specialize in blower door test as well as duct work testing for new construction and existing dwellings. A blower door is a machine used to measure the airtightness of buildings. The blower door test.

During this test a calibrated fan is installed in an otherwise sealed door or window while all the other openings to the exterior are closed. Understanding blower door test results. Door fan test for determining of minimum hold time according to iso 14520. 1 a calibrated variable speed fan capable of inducing a range of airflows sufficient to.

Blower doors consist of a frame and flexible panel that fit in a doorway a variable speed fan a pressure gauge to measure the pressure differences inside and outside the home and an airflow manometer and hoses for measuring airflow. The window and door measurement system allows you to determine the joint permeability of building components in a simple and accurate way. It can also be used to measure airflow between building zones to test ductwork airtightness and to help physically locate air leakage sites in the building envelope. Simply put a blower door is a diagnostic tool used to measure how much air infiltration air leakage occurs in a house.

Blower door test results can determine the airtightness of the building and can be presented in a number of different formats. There are three primary components to a blower door. Last year we built an energy star home for a customer and we used a blower door test to evaluate the houses air infiltration performance.
