The product offers a reliable barrier to the passage of moisture from the ground, enabling a floor to comply with the national Building Regulation requirements, as long as it is installed in accordance with the manufacturer’s instructions.
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.
When can a DPM be installed?
Polythene sheeting is a staple product for any project due to its versatility. It can be used for protecting furniture during house removals, covering floors during building and decorating work, or creating temporary dust screens, to name just a few!
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 DPM 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. 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.Constructed from blown polyethylene material, the high-performing Novia 1200 Vapour Control Layer (VCL) is precisely crafted to meet your needs for regulating water vapour and maintaining airtightness in timber frame constructions. Tailored for application on the warm (insulated) side of buildings, this 1200G VCL fully adheres to CPR standards and is CE-approved as a reliable vapour control layer. 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. Humidity Limitations: 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. These 1200 gauge DPMs from Capital Valley Plastics are designed to prevent moisture from the ground entering a property. The low density polythene sheets create a barrier between a concrete slab or screed and the final flooring finish. Tyvek AirGuard Reflective Vapour Barrier 50m x 1.5m: A high-performance, reflective vapour barrier designed to improve thermal efficiency and control condensation in buildings.
One micron is smaller than a bacteria cell – which isn’t a very helpful scale, considering most of us don’t have a microscope! It can also be used for general DIY and redecoration projects, especially to cover items which require a higher level of protection. If undamaged, it is suitable for reusing again. Extra heavy-duty polythene (1000+ gauge) Comprehensive 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. 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. Our CE approved 1200 gauge damp proof membrane is manufactured to last the lifetime of the floor construction if it is correctly installed and not damaged by subsequent building operations.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.
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? Can the Visqueen Vapour Barrier be used with underfloor heating systems? Yes, the Visqueen Vapour Barrier can be used with underfloor heating systems. However, it is essential to follow proper installation guidelines and ensure that the barrier is continuous and properly sealed at all joints and penetrations. Installing a DPM in the concrete slab helps protect your flooring from moisture transmission. Under normal conditions, the 1200 gauge DPM will remain an effective moisture barrier for the life of the concrete slab. Capital Valley Plastics pride themselves on the durability of their membranes.
