Roof outward humidity flow regulator

This is a stop to the vapour flow, with the important function of regulating the vapour flow from the inside to the outside of the roof

A large quantity of vapour forms in all indoor environments, particularly kitchens and bathrooms, which tends to escape outside due to internal/external pressure balancing. This can occur through open windows or through walls, and even more through the roof. The flow of high quantities of vapours tends to create, at the dew point, condensation that is more difficult to disperse, and which reduces the performance of insulating materials and causes the formation of unhealthy mould on the structures.
Vapour outward flow regulator. sD=20m.

VAPOBAR, a waterproof membrane, is also a temporary protection of the roof during all the construction stages. It can be fixed on top of the roof deck using nails, parallel to the gutter and sealing any overlaps using BITUSTICK.
