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

Product Information

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. 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 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. 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)

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

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. 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. To be Compliant with Current Building Regulations Damp Course should be Built into the Mortar Bed approximately 150mm above Structure Base One micron is smaller than a bacteria cell – which isn’t a very helpful scale, considering most of us don’t have a microscope! 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.

Need Help?

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. 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. When DPM is used in underfloor heating applications, there will be no adverse impact on the membrane.
