Heavy Duty Black Polythene Sheet - DPM 300 Mu - 1200 Gauge - 4 Metre x 25 Metre

Product Information

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.

Damplas Damp Proof Course Membrane is Manufactured to last the lifetime of the Floor Construction when correctly 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. 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. 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.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. 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. 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) 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.

Polythene’s high strength to weight ratio is thanks to the way it is made. During a controlled chemical reaction, single, free-floating molecules of ethylene gas are formed into long, repeating chains – producing a plastic solid. These long chains can be melted together, creating a flexible yet immensely strong material, with the properties we’ve come to know and love. Custom polythene from 32 gauge to 1200 gauge When DPM is used in underfloor heating applications, there will be no adverse impact on the membrane. 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. 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 DPMTo be Compliant with Current Building Regulations Damp Course should be Built into the Mortar Bed approximately 150mm above Structure Base 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? In addition to its adept moisture management capabilities, the Novia 1200 VCL acts as a highly efficient barrier against air leakage, effectively preventing undesired convection flows. To ensure a durable and resilient vapour seal, it is advisable to use this Novia 1200 VCL in conjunction with Novia's compatible butyl and foil sealing tapes throughout its operational lifespan. Features & Benefits: Novia Polythene Vapour Control Layer 1200 Gauge - 4m x 25m Roll 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. 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.

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.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! What accessories are recommended for use with the Visqueen Vapour Barrier? To ensure airtightness, the following high-performance components are recommended for use with the Visqueen Vapour Barrier: Damplas DPM is Premium 1200 Gauge Polythene Sheeting is ideal to protect Buildings against Moisture and has Robust Puncture Protection. UK Manufactured: Made in the UK, this product ensures consistent quality and adheres to stringent manufacturing standards. 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.

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. 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. High Vapour Resistance: With a vapour resistance of greater than 530 MNs/g, this product effectively restricts the passage of warm, moist air from the interior of the building, reducing the risk of interstitial condensation and associated structural damage.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.
