225mm Damcor Insulated Vertical Damp Proof Course (DPC) - 17mm x 150mm - Cavity Closer

225mm Damcor Insulated Vertical Damp Proof Course (DPC) a rolled insulated DPC designed to provide a thermal break and moisture barrier at door and window reveals where the cavity is closed using a returned blockwork detail. It’s a simple yet highly effective solution to combat cold bridging, condensation, and mould growth in traditional cavity wall construction. The Damcor 165mm is a reliable and cost-effective way to improve thermal continuity and moisture control around openings—especially where traditional cavity closers may not be suitable.

• Insulation size: 17mm x 150mm
• Material:
  • DPC: Polyethylene
  • Insulation: Chemically cross-linked polyethylene / EVA foam

CHARACTERISTICS

• Provides a thermal break at the reveal to prevent cold bridging
• Acts as a vertical DPC, restricting moisture tracking from the external leaf
• Reduces risk of condensation, staining, and mould growth at reveals
• Can be cut to length easily with a knife or trowel
• Lap joints can be formed with no loss of thermal efficiency
• Can be built into the reveal as construction progresses
• Single-person fitting; no special fixings required

APPLICATION

• Jambs (vertical sides) of external door and window openings
• Typically used in traditional masonry cavity walls where the inner leaf is returned to close the cavity
• Ideal for builds where standard cavity closers aren’t used, but thermal and moisture protection is still required

CERTIFICATION

• Complies with BS 6515 and BBA standards
