Paper Test
The purpose of this test is to check the compression on the weather-stripping between the sash and the
frame of a projected window. The compression on the inside seal is critical to pressure equalization in
window performance.
STEPS IN A PAPER TEST
1.
Open the vent.
2.
Find a piece of paper or a dollar bill.
3.
Place the paper on the interior vent weather-stripping.
4.
Close and lock the vent.
5.
Resistance should be felt on the paper while trying to pull it back into the room. The weather-
stripping contact between the sash and the frame should provide this resistance.
