Humidity transfer effectively under control
Vapobar has the important function of controlling indoor-outdoor vapour flow. This is done by keeping the diffusion of vapour under control, in order to prevent the formation of condensation, which has harmful effects on the insulation and on the entire roofing system. The vapour is thus eliminated inside the ventilation area.
Alubar is supplied with a special adhesive aluminised tape to be applied over the overlaps.
