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, a new build or simply a DIY installation, our VCLs are built to effectively prevent water vapour from occurring, which can cause damp-related issues and damage in your roofs and buildings.

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 that 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 improve the efficiency of 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’s flat roof 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 stud work of your flat roof, 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, forming your flat roof entirely.

Benefits of Vapour Control Layers

Vapour Control Layers have a variety of benefits to deliver for flat roofs around the UK.

Heat retention

Vapour control layers have the ability to enhance your insulation system by reducing heat loss and improving energy efficiency around your home or property.

Protection

Vapour control layers can ultimately prevent condensation for your flat roofs, which can avoid risks of rotting the joists or rafters found in your roof.

Preventing condensation

The main purpose of vapour control layers is their ability to prevent condensation, which eliminates the chances of mould and rot from forming and damaging the roof structure.

 

VAPOUR CONTROL LAYERS FAQs

Vapour control layers are used to prevent the movement of water vapour into your flat roofs. Vapour control layers do this by preventing excess moisture from entering a wall’s cavity found in your roofs, which are commonly found behind the insulation.

A vapour control layer is always required whenever a home contains a sophisticated insulation system within its walls, such as the insulation installed in your roof. Without a vapour control layer, you run the risk of mould and rot building up within your roof’s structure.

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 roof’s structure from the outside, but allow any water vapour contained within the walls to escape.
