Vapour Barrier Membrane Roof

A vapor retarder is a material or system that is designed as part of the roof system to substantially reduce the movement of water vapor into the roof system where it can condense.

Vapour barrier membrane roof.

Sopravap r sopravap r is an sbs modified bitumen vapor barrier for use in approved multi ply membrane and flashing assemblies. Show the product. Air and vapor barrier membrane redzone. 2 results filter functions.

A polymeric release liner protects the adhesive. Membrain is not intended to be used as an exterior vapor retarder. That reduction of air and moisture infiltration can then help improve roof longevity. A roof design that includes an adhered roof membrane with multiple layers of insulation with board joints offset and staggered over a vapor retarder air barrier helps lower the risk that air and the moisture it carries will infiltrate the roof system.

Air permeable breather membranes air permeable breather membranes have been designed specifically to allow both air and water vapour to pass through the roof or wall of a building. Sopravap r is composed of a proprietary formulation of elastomeric styrene butadiene styrene sbs polymer modified bitumen. A vapour barrier sometimes referred to as vapour retarder is typically a plastic or foil sheet used for damp proofing to prevent interstitial condensation from forming in various building assemblies such as walls roofs foundations and floors. A vapour control layer is typically installed on the warm side of the insulation to block the warm moist air from entering the roof space.

Including flat roof vapour barrier for extra secure roofing solutions. Everyone knows that water in roof systems is never a positive. However it is important to note that vapour control layer timber frame membrane must be installed in conjunction with a good ventilation system and membranes. You ll find pitched roofing products here.

For most areas vapor retarders should be installed on the warm in the winter side of the insulation toward the interior. Looking for pitched roof materials. Reduce heat loss and boost energy efficiency with market leading vapour control layers vapour barrier membrane and vapour control barriers. Vapour permeable breather membranes minimise the amount of water vapour that condenses within the roof or wall space helping to minimise damp mould and rot.
