Vapour Control Layers

UK Flat Roofing supplies a wide range of Vapour Control Layers (VCLs) in order to cater for all roofing projects. Whether it’s a large or small scale renovation or simply a DIY installation, our VCLs are built to effectively prevent water vapour into your building.  

VCLs are used in a range of construction projects and are crucial for preventing moisture from forming within the insulation layer. Without a VCL it is likely to damp and rotting issues would begin to occur over the years. VCLs are also capable of enhancing the energy efficiency of your home, similar to green roofing systems that use natural materials to waterproof your home.
 
Please ensure that all VCLs are sealed securely. Take a look at our selection below.

Installing A Vapour Control Layer 

Internal condensation within a property is a recurring problem that can be expensive to fix. Enter Vapour Control Layers. The correct use of VCLs is an effective method of protecting your property, reducing the chance of damage to the insulation and timbers.

Depending on your wall structure, a VCL can be stapled to the timber studwork with the insulation wedged between the timber studs. Once applied, seal everything including the ceiling, floor and vertical joints where the VCL meets adjoining walls.

FAQs


Vapour control layers are used to prevent the movement of water vapour into the building structure such as your walls or windows. Vapour control layers do this by preventing excess moisture from entering a wall’s cavity - commonly found behind the insulation.

A vapour control layer is always required whenever a home contains a sophisticated insulation system within its walls, irrespective of the insulation used. Without a vapour control layer, you run the risk of mould and rot building up within your home or property walls. 

The build-up of mould or rot can also mean expensive cleaning duties, as it can be difficult to get rid of these substances when they build up in extraordinary amounts. 

Vapour control layers stop water vapour from entering the inside of your home’s structure, whereas breather membranes keep water from getting into the wall from the outside, but allows any water vapour contained within the walls to escape.
