About Airtightness

We are fully qualified professionals who offer you a testing and certification service for air permeability.

Our Friendly and approachable staff will test your building to the required standards and assist you to identify any air leakage paths which may need to be sealed.

Government targets to reduce national CO2 emissions by 20% mean that all new buildings must emit 40% less carbon dioxide than previously allowed.

One way to help reduce heating costs (and therefore CO2 emissions) is to avoid unwanted draughts.

It is our job to check that the building quality is the same as that on the plans.

Careful Design and Build Quality will make it easy to achieve the required standards of air tightness.

Building Regulations now require Air Tightness Testing and certification to show compliance with current legislation.

Energy Matters will test your building to ATTMA TS1 standards using UKAS calibrated equipment and if necessary assist you to identify any air leakage paths which may need to be sealed.

Building regulations from April 2006 require that new buildings comply with ‘Part L’. This means that a percentage of new houses need to undergo air tightness testing, air leakage testing and air permability testing.

Air tightness testing is the procedure to trace any unwanted drafts and uncontrolled airflow through the house. Too much air leakage leads to heat loss resulting in higher C02 emissions. Reducing C02 emissions is the purpose of ‘Part L’ of the new building regulations through air tightness testing, air leakage testing and air permability testing

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.
  • Behind Skirting Boards
  • Behind Coving
  • Boxed in Pipes & Soil Stacks
  • Behind Bath Panels
  • Kitchen Units
  • All Other Surfaces
  • Badly Installed Trickle Vents
  • Windows and Doors
  • Recess Lights
  • Loft Hatch
