AIRSTOP AIRSTOP An effec ve air ght barrier is one of the most cost effec ve ways of reducing heat loss.
Air leakage is the uncontrolled flow of air through the gaps and cracks in the fabric of a building.
Air leakage is one of the most significant factors in heat loss from a building.

Reduced heat loss means greater comfort and reduced bills.

Air ghtness does not mean a lack of ven la on. In fact, correct air ghtness ensures
that ven la on, whether passive or mechanical works efficiently.
The performance of other elements of a building are also affected by the performance
of the air ght layer. These include insula on, windows and mechanical heat
recovery ven la on systems.
The air ght barrier also acts as a vapour control layer,
ensuring the controlled release o moisture and protec ng
the fabric of your building from damage such as rot and AIRSTOP System AIRSTOP System
mould build up. A low air ght test is an unambiguous
indica on of build quality
