Product Information

How should the Visqueen Vapour Barrier be installed? The Visqueen Vapour Barrier should be installed according to the recommendations of BS5250: 2002 ‘Code of practice for control of condensation in buildings’. It is essential to ensure that the vapour barrier is continuous and properly sealed at all joints and penetrations, using the appropriate tapes and accessories.

Versatility: Suitable for a wide range of internal building conditions, the Visqueen Vapour Barrier DPM can be used within roofs, walls, and floors, making it a valuable addition to your construction project. When DPMs overlap you should use DPM tape to seal the joints. We sell both single and double sided DPM tape. Your DPM always needs to be continuous with the damp proof course (DPC) in the walls etc. Benefits of DPMComprehensive System Components: Visqueen offers a range of high-performance accessories, including jointing tapes and flashing tape, to ensure a complete and airtight vapour control system. DPM must be covered by a screed or other protective layer as soon as possible after installation. Care should be taken to ensure that the membrane is not stretched or displaced when placing the concrete or screed over the membrane. Sufficient allowance should be made to avoid bridging (i.e. creating areas of unsupported membrane) during screeding operations at internal angles, etc. To be Compliant with Current Building Regulations Damp Course should be Built into the Mortar Bed approximately 150mm above Structure Base Is the Visqueen Vapour Barrier suitable for both residential and commercial buildings? Yes, the Visqueen Vapour Barrier is versatile and can be used within roof, wall, and floor constructions in both residential (such as timber frame housing) and commercial buildings.

Installation Complexity: Proper installation of the Visqueen Vapour Barrier requires adherence to the recommendations of BS5250: 2002 ‘Code of practice for control of condensation in buildings’, and may necessitate the use of various tapes and accessories to ensure a continuous and properly sealed barrier. DPM membranes are laid either under a new concrete slab or on top of it to prevent moisture transmission. Ordinarily you will have a bed of hardcore on the ground then either a blinded surface and a DPM before a layer of concrete, or you place the DPM on top of the concrete slab before the final flooring. If you suspect the groundwater to contain sulphates, then the DPM should always be placed below the concrete. A DPM (damp proof membrane) is a plastic sheet membrane that sits between a concrete slab or screed, and acts as a barrier to stop moisture and contaminants entering a property from the ground. When can a DPM be installed? When DPM is used in underfloor heating applications, there will be no adverse impact on the membrane. Can the Visqueen Vapour Barrier be used in high humidity environments? The Visqueen Vapour Barrier is designed for use in environments with humidity levels less than 60% at 20 degrees Celsius (BS5250: 2002 class 2 and 3 conditions), making it less suitable for buildings with higher humidity levels or more demanding conditions.

When can a DPM be installed?

While there are a few users who have experienced limitations in high-humidity environments, the overall consensus is that the 1200 Gauge Visqueen Vapour Barrier DPM 100m2 (50m x 2m) is an exceptional product that lives up to its promises. The quality and performance of this UK-manufactured vapour barrier make it an excellent investment for those seeking to protect their buildings from the harmful effects of condensation. Damplas Damp Proof Course Membrane is Manufactured to last the lifetime of the Floor Construction when correctly installed. As the word “duty” implies, each range has a usage application, ranging from very light use, like a garment separator sheet – to super heavy applications, like a membrane sheet for use in the construction industry.
