When condensation occurs within a building’s structure, it may cause significant issues that prove costly to rectify. Air and Vapour Control Membranes (or AVCL, Vapour Control Layers, VCL’s) play a crucial role in limiting the passage of moisture-rich air into the building’s fabric – safeguarding and providing longevity to the building’s structure.
What is a VCL and why are they needed?
AVCL’s or VCL’s are membranes which are installed on the warm interior side of a building. They are primarily designed to control the amount of moisture which passes through the fabric of the building. An AVCL will also provide an air tight barrier to limit heat loss and eliminate the passage of air in or out of the construction.
AVCL’s are required to be installed to ensure that the occurrence of interstitial condensation does not form within the building’s fabric. Installing an AVCL to the warm side of an insulated wall construction can also help to ensure that damp or mould will not occur internally within a habitable space.
