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

Product Information

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!

Damplas DPM is Premium 1200 Gauge Polythene Sheeting is ideal to protect Buildings against Moisture and has Robust Puncture Protection. 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. 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.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. 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 is ideally equipped to safeguard buildings against moisture, rising water and damp from the ground. 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.

When DPM is used in underfloor heating applications, there will be no adverse impact on the membrane. 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. To be Compliant with Current Building Regulations Damp Course should be Built into the Mortar Bed approximately 150mm above Structure Base 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. 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.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. 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.

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.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. 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. 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.
