One side of this 8.5×11 durable sheet covers blower door set up, testing, and evaluating of test results. We also cover analog and digital manometers, leakage values of building materials, can’t reach 50 factors, building tightness limits, and simple house-pressure testing.
The flip side covers testing ducts with a pressure pan and finding duct leaks by sight and touch. It describes the typical duct-leakage locations.
This quick reference sheet is designed for air-sealing technicians, sealing air leaks during blower door testing, and who seal ducts in homes. Order online now!
