Possible Air Leakage Areas

The areas listed below are common causes of uncontrolled air leakage areas, we recommend you take care and attention in sealing these areas whilst in the process of construction;
Intermediate Floors- Use joist hangers where possible, if built into the walls seal with a flexible sealant.
Behind Skirting Boards-seal between floors and walls
Behind Coving-seal between wall and ceiling
Boxed in Pipes & Soil Stacks-seal when pipes/soil stacks go out through the ceiling into the roof space
Behind Bath Panels-seal all services and pipe work that penetrate the envelope of the building
Kitchen Units-seal all services and pipe work that penetrate the envelope of the building
All Other Services-pipe work and services that enters the building ensure a good seal
Badly Installed Trickle Vents-the test only allows for trickle vents to be shut and not sealed
Windows and Doors-ensure a good seal behind plaster board as well as decorators finishing mastic
Recess Lights-ensure they are fire check fittings that are fitted correctly
Loft Hatch-poor quality loft hatches often leak
Any Remedial Work to Floorboards-make sure any holes in timber floorboards are refitted correctly and sealed
Please do not hesitate to contact us if you have questions relating to the process of sealing any air leakage areas in preparation for the air tightness test.
