Airtightness

Airtightness is often the forgotten factor when building low energy buildings. However, designing and implementing a superior level of airtightness reduces a building’s energy costs. It also makes for a quieter and more comfortable interior space – no drafts, much less noise transmission from outside. Installing MVHR allows you to double down on airtightness whilst enjoying much better indoor air quality. Improving your airtightness performance allows you to get the most benefit from your MVHR system.

To achieve a higher level of airtightness, a designed, continuous airtightness layer on the inside of the thermal envelope must be defined before building work starts. You need to consider window and door frame junctions, service penetrations (utilities, telecoms) as well as floor-wall and wall-ceiling or roof junctions. Good airtightness means thinking through the sequencing of how you build. If this is planned for before starting on site, you will achieve a better and more cost-effective end result.
