Air leakage tests on synthetic rubber strips. Funktionsprovning av tatningslist

Studies effect of joints between building components on air tightness of buildings, and the factors which influence the air leakage through a joint. As a pilot test, the air leakage for different widths of joints between building components in timber has been studied by varying the pressure between 150 to +/- 700 pa. Describes main apparatus and gives results of the investigation on the leakage of air pressure in various types of joints.
