Blower Door Tests

What Are Blower Door Tests?
Blower Door tests are an accurate and scientific way of demonstrating where a building has air leakage. A powerful fan is placed in an entrance door of a building. A frame around the fan seals the doorway. When the fan is turned on measurements are taken from the gauges connected to the fan apparatus. These measurements are entered into a computer program that calculates the air leakage based on the guage measurements. The output from the computer represents every crack and crevice that is leaking air into the building. This is then represented as air changes per hour. Some homes have many air changes per hour through air infiltration. The WALLSEAL system dramatically reduces air infiltration by sealing most of the cracks and crevices. This results in a tighter more energy efficient home.

Comparing
Fiberglass vs. WALLSEAL

The following tests were done on identical homes. The home with the 2x4 walls was insulated with WALLSEAL. The home with the

2x6 walls was insulated with fiberglass batts.

MINNEAPOLIS BLOWER DOOR

June 3, 1987

2x6 Fiberglass Walls

Area = 3,162 Square feet

Volume = 16,800 cubic feet

Air Changes per hour at 50 pa = 9.54

Equivalent square inches = 307.88

Leakage Ratio = 9.73 sq. in. per 100 Sq. Ft.

MINNEAPOLIS BLOWER DOOR

June 3, 1987

2x4 WALLSEAL Walls

Area = 3,162 Square Feet

Volume = 16,800 cubic feet

Air Changes per hour at 50 pa = 1.15

Equivalent square inches = 50.38

Leakage Ratio = 1.59 sq. in. per 100 sq. ft.
