Collection: Vapour Control Layers - VCL

What is VCL?

A VCL, or Vapour Control Layers, is a layer that is inserted like insulation, which helps to protect any building from the consequences of condensation. The idea of VCL is that it blocks the passage of warm moist air entering the structure, here a roof, so that condensation cannot form, thus avoiding its damaging consequences. Vapour Control Layers should be considered as important Roofing Materials, as VCL is an important component as it acts as a protective layer to ensure that warm moist air will not enter your structure. A VCL is still important to use in conjunction with other Roofing Materials like membranes and ventilation. A VCL will prevent damp and mould from occurring in any homes or buildings, which helps prevent respiratory issues states the NHS. Not only will VCL prevent significant health problems, but Vapour Control Layers will help to avoid structural issues that can occur due to condensation, such as weakening timbers and the corrosion of other materials. A VCL has another great benefit to it, as Vapour Control Layers help to prevent installation becoming damp, which then causes insulation to lose its thermal properties. These are just some reasons why a VCL is such an important part of insulating your roof and other areas.
