The vapour barrier racking board has a transparent airtight vapour control coating on both sides. Our range. A typical concrete floor build up that incorporates a VCL would be as follows: Overlaps of the VCL membrane are sealed together with Double Sided Tape and the face of the joint sealed with Single Sided Foil Tape. As well as this, the installation process . This will also help protect the insulation from wet screed or concrete. To ensure a good bond and tight sealing, it is crucial to press the tape firmly onto the membrane and to the item being sealed. However, when using vapour impervious insulations in timber frame construction, any condensation forming in the walls tends to be absorbed by the timber, a process that can cause rot. 48.90 inc. VAT. The top suface has a sanded finish. A 'vapour control layer', or 'VCL', reduces the water vapour transfer through any building and reduces the risk of condensation forming.

Felt Products Green Vapour Control Layer (Vapour Barrier) - 50m x 4m. In simple terms, a vapour control layer is a layer on the inner face of the building which is used to reduce moisture flow into and through the walls, roof or floor. . The first graph displays the relative humidity of the internal surface of the stone. A vapour control layer is designed to catch this vapour, preventing it from condensing on the insulation or elsewhere in the loft space or attic. Rising energy costs are just one of the motivating factors that have builders implementing exterior insulation in the homes they're building. The idea behind a vapour control layer is to install it on the room (i.e. However, as a simple acronym, there is a problem because in most applications a specific level or type of performance is required, as a 'catch all' acronym VCL is wide open to . as well as the installation process, play an equally important role as the vapour control layer itself. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); We offer CPD training for architects practices across Devon and Cornwall.

The notion behind a vapour control layer is to install it on the room side of the insulation so it stops the passage of warm moist air entering the structure. Following accelerated heat-aging at 135C for 105 days. Gerband SD Control is best while being used indoors as a vapour barrier. In this guide, we look at how vapour barriers work, why you need them and how to install them. Care should be taken to seal all laps, penetrations, perimeters, junctions, and accidental punctures.

Suspended timber floors are slightly different. A Vapour Control Layer, or VCL for short, is a plastic layer that restricts the movement of warm, moist air from inside a property into the fabric of the building. The function of a vapour control layer is to avoid moisture that builds up inside a house, to find its way to the insulation material, which then will absorb the moisture making the insulation material lose its ability to insulate. The special film applied on both sides of the board act as effective airtightness and vapour control layer. This, however, can only be realistically achieved if the standard of installation is high. It comprises an impervious aluminium core, reinforced with polyester and coated with a specially formulated quick melt SBS modified bitumen. Profoil 861. Wall installation for vapour control layers Generally speaking when you install a VCL to the walls of existing properties, you are installing a stud wall with insulation.
