What Is A Blower Door

A pressure gauge connected to the blower allows operators to measure air pressure changes.

What is a blower door.

What is a blower door. A powerful variable speed fan mounts into the frame. The higher outside air pressure then flows in through all unsealed cracks and openings. A flexible door that seals around an opening in a building typically an doorway.

When turned on the fan pulls all the air out of the house and lowers the air pressure inside. Blower doors have been around for a while. Essentially a blower door is a very powerful fan that is fixed into the frame of an exterior door. Blower doors are arguably the most important tool for making your home more comfortable and efficient.

A blower door consists of a frame and flexible panel that fit into an exterior doorway. The fan pulls air out of the house lowering the air pressure inside. The higher outside air pressure then flows in through all unsealed cracks and openings. There are three main parts to a bower door.

The auditors may use a smoke pencil to detect air leaks. A blower door is a powerful fan that mounts into the frame of an exterior door. This results in the higher outside air pressure flowing into the house through any unsealed cracks and openings revealing the air infiltration rate of the home and showing where an air leak may be hiding. Here is what a reading on the blower door looks like.

A blower door is a machine used to measure the airtightness of buildings. Here is what a blower door looks like. We ve discussed the benefits of airtightness previously. A calibrated variable speed fan capable of inducing a range of airflows sufficient to pressurize and depressurize a variety of building sizes a pressure measurement instrument called a.

In this episode we re jumping straight in to look at the blower door. There are three primary components to a blower door. The fan blows air out of the house lowering the inside air pressure. A large plastic or wooden frame is placed into an exterior door frame within the building.

Commercial blower doors are high capacity calibrated fans that are installed in a door in order to measure how leaky your home is and to allow easier spotting of leaks so they can be sealed. While a blower door test does not evaluate how well a structure is insulated it can reveal drafty walls and air bypass situations that could undermine otherwise well insulated wall assemblies. This frame includes a specially made cutout designed to hold a fan or blower. A blower door test is a way to check how air tight a structure is.

It is designed to check for air leaks in walls attics and mechanical penetrations.
