A94 Air-Tightness Testing On-Site Checklist

A94 Air-Tightness Testing On-Site (Checklist)
About:

Problems:

  • ATL of 10 at 50 Pascals set by Building Regulations Approved Document L is a very leaky building
  • Wind will whistle through gaps in windows and papers will flutter across tables
  • This level of performance in new build is fundamentally incompetent
  • What is scary is that UK Construction Industry find it hard to get 10

Misunderstandings:

  • Airtightness is often seen as a problem, it’s better to refer to air-leakiness, waste heat energy, cold drafts, and thermal comfort.

Solutions:

  • Results of 1 air leakage rate at 50 Pascals is better but Europeans are used to 0.3 and better
  • Passivhaus levels of performance: 0.6 for new build and 1.0 for refurbishment

Value Engineering:
(looking at the bigger picture)
(getting stuff into projects, not just out of them)

  • Carry out the wind/air tightness testing once the building fabric is in place, do not wait for finishes to be installed.
  • Test the building fabric not the finishes, the finished can be replaced at shorter life intervals without having to re do the testing.
  • Testing the finishes will mean you may end up sealing every screw hole for every object hung on the wall lining.
  • Testing and sealing the finishes means the air space behind the linings is still subject to thermal flanking, eddie currents, heat loss and coolth gain through leaky external fabric
  • If the sarking or lining board/sheet is airtight then only the joints need to be taped to maintain integrity of the board/sheet performance.
  • Be sure to test the board/sheet before installing them.
