Benefits of airtightness

Only when the construction is airtight can warm air be retained within the building and cold air kept outside. Preventing unpleasant draughts gives greater thermal comfort and increased energy efficiency, which in turn leads to lower heating costs.

Airtightness also protects the building fabric against damage, helping to maintain its appearance and extending the building’s life.

But the benefits are not purely financial, as high levels of airtightness also ensure healthy indoor air quality for the occupants.
