Air Tightness

If you are planning on installing a Heat Recovery Ventilation system - it is beneficial to try and ensure that there is little or no Air Leakage in the property. Making a property as Air Tight as possible will prevent  the uncontrolled  flow of cold outside air into a building and the loss of warm air.


At BM Air Conditioning - as part of the services we provide  - we can check for and remove air leakage - making your property as Air Tight as possible.

Air Leakage  typically take place through:

  • joints, gaps and cracks in the construction
  • gaps created where the structure penetrates the outer skin of the building
  • cracks around door and window openings
  • gaps where services enter the building
