Insulated DPC 225mm x 10m

Insulated Damp Proof Course (DPC) is a high-performance, dual-purpose membrane designed to prevent both moisture migration and cold bridging around structural openings. The product consists of a premium polyethylene DPC bonded to a strip of expanded polystyrene (EPS) insulation. This combination allows the DPC to act as a traditional moisture barrier while the insulation core minimizes heat loss at the junction between the window or door frame and the wall. By providing a continuous thermal break at the reveal, it significantly reduces the risk of internal condensation and the subsequent formation of mould, ensuring a healthier and more energy-efficient indoor environment.

Benefits

• Provides a superior damp-proof barrier while simultaneously eliminating cold bridging
• Significantly reduces the risk of condensation and mould growth around internal reveals
• Flexible design allows for easy installation around corners and complex structural details
• Lightweight and easy to cut, speeding up the installation process on-site
• Helps buildings achieve compliance with thermal performance standards in Building Regulations

Good to know

• Each roll typically measures 10 metres in length
• Available in various widths, with a standard thickness of 30mm for the insulation core
• The insulation is manufactured from high-grade EPS with a thermal conductivity of 0.038 W/mK
• The DPC element is 500 microns thick and fully compliant with BS 6515
• For a correct installation, the insulated side should face the cavity, ensuring it is butted tightly against the frame
• It can be easily fixed into position using stainless steel staples or a suitable grab adhesive before the frame is fitted
