To assist in achieving low air leakage rates, the following suggestions will be of help:

How to achieve a good air test result…

Most importantly, when external walls have ‘dot and dab’ plasterboard, ensure that your plastering contractor installs a solid bead of adhesive to the bottom of each plaster board to form a continuous bead behind the skirting . This is even more critical if oak/wood floor is to be used. Also, this is essential where skirting is not going to be fitted.


  • Radiator pipes should be sealed where they emerge from the floor but, more importantly, where flexible piping is used and fitted through the plasterboard behind the radiators proprietary fittings should be used and additionally sealed if ill-fitting.

  • Skirting to all rooms should be sealed top and bottom including skirting to internal walls.

  • If wooden flooring or tiles are fitted prior to fitting the skirting, the plasterboard needs to be sealed against the floor and ideally the skirting sealed top and bottom once fitted.

  • Internal soil stacks should be sealed where they penetrate through floors or into the roof space, also where soil pipes enter the ‘boxed’ sections they should be carefully sealed.

  • Trickle vents should be sealed prior to attendance of air test operative.


  • Fit skirting behind kitchen units or seal between the bottom of the plasterboard and the floor prior to fitting units.

  • Silicon seal where wastes and pipes penetrate through the plasterboard.

  • Boiler exhausts/vents should be sealed where they penetrate the wall.

  • Pipes from the boiler should be sealed where they penetrate the ceiling.


  • Bath/sink and toilet wastes and water supply pipes should be sealed where they penetrate the floor or walls.

  • In some instances ‘traps’ fitted beneath baths and specifically shower trays are ‘cut’ in to the floor to allow for their physical size and to make fitting easier. The cutting away of sections of flooring for this purpose causes serious air leakage and should be avoided wherever possible.

  • Bath and shower panels should be fitted and sealed.
