Vapour Control Layer (VCL) is mostly used in timber frame constructions, but can also be used in a wide variety of other applications such as flooring and ceiling projects.
The product is made with top grade material thus meeting NHBC standard 6.2.
The Vapour Control Layer (VCL) is made within strict working tolerances of our ISO9001 Management System.
Ideal for keeping a structure protected during construction projects, for example, exposed roofs or door/window openings.
Advice & Guide to Vapour Control Layers
Each roll is uniquely labelled and registered. Various roll sizes to suit standard floor to ceiling measurements, reducing wastage and increasing efficiency. It is available in clear or green tint so fixing points are easy to locate through the product.
How to install the Capital Vapour Control Layer
This high-performance vapour control layer 125mu from Capital Valley Plastics minimises the risk of condensation within the structure of a building. It acts as a vapour barrier, restricting the passage of warm, moist air within the structure or the roof of a property. In turn, this dramatically reduces the risk of damp and rot developing within the fabric of a building.
A vapour control layer or VCL membrane is an important part of new build construction because condensation or water vapour can build up between the layers creating rot and mould.
Our high performance VCLs are suitable for wall, floor, and roof constructions. They are normally used with timber frame constructions and situated on the inside of the framework.
This 125 micron vapour control layer is suitable for use with our range of cavity drain membranes, either above or below ground. It needs to incorporate a mechanically-fixed batten and board system with insulation to the cavity drain membrane.
VCLs should be located inside of the warm side of insulation – this is the room side of the structure. If you are using on timber framework, you should fix the VCL with nails.
When installing a vapour control layer, make sure all laps and edges are fully sealed and taped. VCLs can be sealed using double-sided DPM tape.
