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.

Flat roof insulation vapour barrier.

Next to that you may also buy a moisture regulating vapour barrier membrane that can manage the damp even better. Flat roof vapour barrier materials when constructing a flat roof there are two types of materials commonly used. Vapour control layers vcl. However we lose r value where the taper is thinnest and need to insulate under the sheeting.

The notion behind a vapour control layer is to install it on the room. A vapour barrier will then need to be installed to reduce condensation in the roof structure. If the roof is insulated with foil faced insulation blankets the aluminium side can serve as a vapour barrier at the same time. We are insulating a flat roof with tapered rigid insulation over a moisture barrier and then capped with modified bitumen.

A vapour control layer helps you shield your building from the consequences of condensation condensation is generated when warm moist air rises and condenses into a liquid on contact with the cooler areas above the insulation. A flat roof vapour barrier such as iko s mvp modified vapour protector offers appropriate moisture protection. However note that one should seal the seams here as well. Including fibreglass roof kits torch on felt and liquid rubber products everything you need for flat roofing is in one place.

The insulation and vapour barrier can be mechanically fixed using fasteners and washers or a self adhesive vapour barrier such as alutrix can be installed with insulation bonded on top using pu adhesive battens.
