Moisture condensation is common where humidity and temperature fluctuations occur outside and when conditions or activities inside a building create moisture. In addition, creating more airtight buildings can actually trap moisture inside the building. Left untreated, moisture can cause damage and corrosion of metal decking, roof panels and fasteners in the roof structure.
Preventing or minimizing condensation can be achieved with careful design of a building’s roof system including the use of vapour control layers or moisture barriers.
Breathable Vapour control layer will allow moisture to dissipate through the membrane and rid the building of moisture.
