Rhinoplast Evolution Gas DPC

Rhinoplast Evolution GAS DPC is a high specification embossed multi-layer damp proof course (DPC) specifically developed for use on brownfield and contaminated construction sites.  Designed to be sufficiently durable to build into perimeter cavity and load bearing walls as part of a gas barrier membrane system to resist moisture and ground gasses, including Volatile Organic Compounds (VOC’s), Hydrocarbons and others, such as Methane, Radon and CO². 

Roll Length: 20m

Roll Width: from 300mm -1200mm. Custom widths available.

Colour: Grey

Thickness: 500µm

  • CE Mark to EN 14909:2012 type A
  • Meets guidance and all recommendations set out in BS8485:2015 + A1:2019 (Table 7)
  • Incorporates guidance outlined in CIRIA C748 for VOC protection
  • Suitable for all characteristic Gas Situation (CS) ground gas regimes
  • Conforms to the specification requirements of NHBC Amber 1 & Amber 2 applications.
  • Preformed Components and Tapes available

The Evolution Gas Damp Proof Course was developed for all masonry wall construction types and is manufactured at 0.5mm thick using latest co-extrusion technology to produce a flexible 14-layer combination of high-performance engineering polymers that cannot de-laminate containing 2 independent layers of gas resistant polymer (EVOH) to offer exceptional gas protection and moisture resistance into buildings.

The Evolution GAS DPC provides gas resistance, robustness, and exceptional strength without the requirement for reinforcement or containing aluminium layers and will maintain maximum durability in application.  It is supplied in 20mtr rolls and in standard widths 300mm, 450mm, 550mm, 600mm, 650mm, 750mm, 900mm and 1200mm. The system incorporates an extensive range of preformed components to maintain the integrity of the system to be installed in accordance with the relevant sections of BS 8215:1991, PD6697:2019 and BS 8000-3:2020 and joined using sealing tapes or easily heat sealed/welded for VOC applications.
