Tyvek Flat Roof Vapour Control Layer

Tyvek breathable roof membranes are suitable for non ventilated pitched roof applications only.

Tyvek flat roof vapour control layer. The design of tyvek airguard allows for faster evacuation of built in humidity in new construction elements. Overview an airguard vapour control layer can significantly reduce heat loss and increase energy efficiency. Using a tyvek weather barrier in combination with a vapor barrier depends on how the rest of the wall system is constructed and the climate the building is in. A smarter way to buy building materials.

Tyvek airguard control vapour control layer 50mtr x 1 5mtr. If the majority of the year is spent heating the home where the inside temperature is greater than the outside it is generally good to use a vapor retarder behind the interior drywall. By controlling heat transfer and reflecting heat inside the building they help keep buildings cool in summer and warm in winter. Dupont tyvek airguard control is a tough transparent vapour control barrier that improves airtightness by reducing convective heat loss and air leakage while also minimising the risk of condensation in roof and wall insulation.

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. A continuous layer of dupont airguard control reduces air leakage by providing an effective vapour control barrier to control air movement and moisture infiltration around the habitable space of the building.
