Determine Air Tightness
Turn Cycle Solutions uses blower door tests to help determine a home’s air tightness.
· Reducing energy consumption due to air leakage
· Avoiding moisture condensation problems
· Avoiding uncomfortable drafts caused by cold air leaking in from the outdoors
· Determining how much mechanical ventilation might be needed to provide acceptable indoor air quality.
How They Work
A blower door is a powerful fan that mounts into the frame of an exterior door. 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. The auditors may use a smoke pencil to detect air leaks. These tests determine the air infiltration rate of a building.
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.
Our calibrated door has several gauges that measure the amount of air pulled out of the house by the fan. The calibrated blower door’s data allow us to quantify the amount of air leakage and the effectiveness of any air-sealing job. Then we will provide specific information regarding how to fix these issues and balance your home’s efficiency, saving you money.
