About this deal

Step one: Fix Celotex sheet to external sheathing using galvanised clout nails – 400mm centres in the centre of the board and 300mm centres around the parameter. Face unprinted foil surface towards the air cavity for optimum thermal performance. Ensure to carefully align fixings with underlying studs, sole plates and headrails. Using impermeable materials when combined with air conditioning has been linked to mould build up inside the building. Do not use on two sides The problem with this however means, in cold climates we are letting the warm air out of our homes when our homes now more than ever need to be more energy efficient. Do I need a vapour barrier? There are some materials that will act as both an air barrier and a vapour retarder such as polyethylene plastic sheets, builders foil, foam board insulation and other exterior sheathings. Materials that include any of these will also work.

Step one: Make sure all services are installed and that all studs and rails are flush with no projections. Split-ability. Likewise, you want tape that’s easy to cut or split for application but that won’t tear by accident and ruin the moisture-resistant capabilities.The confusion can come because a vapour barrier can act as an air barrier but an air barrier should not stop vapour from defusing. If the roof is insulated with foil-faced insulation blankets, the aluminium side can serve as a vapour barrier at the same time. However, note that one should seal the seams here as well. Next to that, you may alsobuy a moisture regulating vapour barrier membrane that can manage the damp even better.

Interstitial condensation within a property’s structure can be a serious problem and one that’s expensive to remedy. The correct use of Vapour Control Layers is one way to protect the fabric of a building and reduce the chance of damage to the insulation and timbers. In this guide, we look at how vapour barriers work, why you need them and how to install them. What is a Vapour Control Layer & how do they work? Interstitial condensation can occur in insulated lofts which have non-permeable roofing felt. This results in white fluffy mould on the underside of the roofing felt.Product certificates are issued based on test results, calculations and other specific verification However in colder climates class l or class ll vapour retarders are advised in all new constructions such as glass, sheet metal and polyethylene sheets. Make sure it is continuous
