Commercial Air tightness Checklist

Before we arrive on site please ensure you have sent us the design air permeability figure and been through the checklist below, this will greatly increase your chances of passing first time.

 Internal doors to riser cupboards may be closed but should not be artificially sealed.
 Lift doors should be closed (but not artificially sealed). Any external lift shaft vent should remain open.
 All drainage traps should be filled with water.
 All incoming service penetrations (e.g. power, telecoms) should be permanently sealed.
 All external doors and windows should be closed (but not artificially sealed). This includes door thresholds. The exception to this will be apertures to which test equipment is connected.
 Smoke vents should be closed but not artificially sealed.
 Background trickle ventilators, passive ventilation systems and permanently open uncontrolled natural ventilation openings should be permanently open. Uncontrolled natural ventilation openings should be temporarily sealed.
 Mechanical ventilation and air conditioning systems should be turned off. These systems should be temporarily sealed to prevent air leakage through the systems during the test.
 External doors, windows & manual vents need to remain closed for the test. All internal doors need to be propped open.
 We do require a door frame of standard size to fit our square adjustable frame. You may need to modify the opening to suit our template. Minimum size opening 700 x 1300mm/ Maximum 1100 x 2400mm
 Testing equipment is usually powered by 240v power supply. We must be informed in advance if this will not be available.
