Tyvek Flat Roof Vapour Control Layer

At roofing superstore our choice of flat roof materials includes everything you need to create a long lasting weather proof flat roof that performs and looks good too.

Tyvek flat roof vapour control layer.

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. 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. Overview an airguard vapour control layer can significantly reduce heat loss and increase energy efficiency. Tyvek breathable roof membranes are suitable for non ventilated pitched roof applications only.

Tyvek airguard control vapour control layer 50mtr x 1 5mtr. What is the difference between a non ventilated system and a sealed system. By controlling heat transfer and reflecting heat inside the building they help keep buildings cool in summer and warm in winter. 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.

Tyvek airguard smart is an innovative air and vapour control layer which protects structures against environmental damage by adapting to various moisture conditions and regulating the humidity in building elements. 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. Vapour control layers are positioned to the inside of the insulation in order to minimise the amount of warm moist air entering the construction. A smarter way to buy building materials.

In flat roofing a tyvek roof membrane may only be used as a protection layer over insulation or as a separation layer between metal sheeting and a supporting deck. The design of tyvek airguard allows for faster evacuation of built in humidity in new construction elements.
