What is building air tightness? uilding air tightness describes the degree of air leakage into and out of the building''s thermal enclosure which separates conditioned space from the outdoors. Air leakage is the uncontrolled flow through the thermal enclosure due to pressure imbalances caused by wind, stack effect, and mechanical equipment
It is a requirement of Approved Document L that any dwelling tested must achieve an air pressure test result (or air permeability) of less than or equal to 8m3/h/m2 at a pressure differential of 50 pascals with the Blower door a high-pressure testing method or 1.57m3/h/m2 at a pressure differential of 4 pascals with the Pulse a low-pressure
With more stringent building regulations requiring better energy efficiency, air tightness is an increasingly important issue. The aim should be to ''build tight – ventilate right''. How long does an Air-tightness Test Take? The time a test will take to run depends on the size of the building, but it will generally take about 3 hours.
