When do I need an Air Tightness Test?
Ideally the test should be undertaken when the building is as close to completion as possible. As a minimum the building envelope needs to be completed, all major penetration to walls and floors must been made however it is not necessary to be decorated or carpeted.
How we can help to PASS an Air Tightness Test?
We want to help our clients ensure their buildings pass this test first time. Therefore, we’ve designed a simple check list and easy guide to passing an Air Tightness Test:
- Your external walls, ground and roof are fitted & complete (including doors, windows & cladding).
- All fixtures and fittings are installed (including all lights & sockets).
- The plumbing work for the building is complete.
- Service pipes passing through external walls & ceilings are sealed.
- All your skirting boards are fitted & sealed at the top & bottom.
- If there is no skirting board (i.e. behind kitchen units, baths) expanding foam should be used to seal where plasterboard meets the floor.
- All loft hatches/storage doors into roof voids are fitted with appropriate draft excluders.
- All housing services (pipes, electric cables, stacks, etc) are boxed in and sealed.
- There is at least one standard size door in the property that is no more than 2.25m tall by 1.1m wide.
- Any integral garage doors are fitted with draft excluders.
Designed ventilation systems are excluded from this test. Our technicians will tape up all extractor fans, chimneys, MVHR units, etc to give a more reliable testing score. Overall, this will provide you with an extremely accurate score.
All of our tests are carried out in accordance with ATTMA TSL1 (domestic) or TLS2 (commercial) and all our engineers are trained and registered members of ATTMA.
