1984 Blower Door Test results I have about 3100 sq feet and completed my first blower door test. The result was 3300CFM50 or 8 ACH50 so I was told by the vendor. This test was completed in 2011. I have sealed all the kneewalls and floor baseboard areas. Also sealed the attic, Garage, resided two outside walls and resheathed. Though the building leakage curve can be estimated using a single-point blower door test, the curve is more reliable when a multi-point test is used. The test performed in the example above was an ASTM E779 multi-point test. The leakage rate at 60 pascals was 806 cfm, and at 18 pascals, 339 cfm. 2018 Blower Door Testing. R402.4.1.2 Testing. The building or dwelling unit shall be tested and verified as having an air leakage rate of not exceeding 5 air changes per hour. Testing shall be conducted with a blower door at a pressure of 0.2 inches w.g. (50 Pascals). What minimum specs would an old furnace fan (or new Harbor Freight fan) need to have to do decent blower door directed air sealing work on an old leaky house? (Not necessarily for a DIY blower door scoring). Say, for example, a 2000 sq ft house with a blower door score of 2500 CFM at 50 Pa. The smoke pen is a simple test tool used to pinpoint air leaks. It has a wick that is lit on fire with a lighter or match. Once the wick has burned for a few seconds, you blow out the flame and allow the wick to smoke. The smoke lasts only a few minutes; when the the pen stops smoking, you will have to re-light the wick.
