Breather membranes are positioned to the outside of the insulation acting as a weather barrier while still allowing moisture particles to escape from the inside. The notion behind a vapour control layer is to install it on the room side of the insulation so it stops the passage of warm moist air entering the structure.

A vapour control layer or vcl on a warm flat roof sits between the roof decking and the insulation. Vapour control layers are positioned to the inside of the insulation in order to minimise the amount of warm moist air entering the construction. An effective vapour control layer at ceiling level an unobstructed 50mm ventilation space above the insulation. Because of this the vcl always sits at the warm side of the insulation.
