Quinn Therm QW Cavity Wall Insulation Board 1200mm x 450mm x 75mm

Quinn Therm QW Cavity Wall PIR Insulation is a high performance, fibre free board, with a rigid thermoset insulation core and faced on both sides with a low emissivity composite foil facing, for use in partial fill cavity wall applications. The low emissivity foil facings increases the thermal resistance of the residual cavity and reducing the overall U-value of the wall. The good dimensional tolerances of the QW Cavity Wall PIR Insulation board enabling it to be tightly butted to form a continuous layer of insulation.

PIR Cavity Wall Insulation Board 75 x 1200 x 450mm

Product Information

PIR Cavity Wall Insulation is the most popular type of rigid insulation wall boards, comprises a fiber-free rigid polyisocyanurate (PIR) insulation core with aluminium foil composite facing on both sides. It has a high compressive strength, improved insulation & durability. Moreover, it provides improved fire resistance and moisture tolerance.

Use & Application

Due to its high-performance insulation, the PIR wall insulation board is suitable for cavity wall applications with maintaining a residual 10mm cavity. This will help the board to resist moisture transfer and aid installation.

  • Domestic and most commercial applications
  • New Builds
  • Refurbishment projects


  • Excellent thermal & fire performance
  • Environmentally friendly
  • Durable and maintenance-free
  • Provides a cost-effective mean of reducing CO2 emissions
  • Will optimise the performance of underfloor heating

Kingspan Kooltherm K103 Insulation Board PK4 2400mm x 1200MM x 75mm

Kooltherm Kooltherm K103 is a premium performance floor insulation board, with a lower lambda value and a fibre-free rigid thermoset phenolic core. Benefits: Premium performance rigid thermoset insulation – Thermal conductivities as low as 0.018 W/m.K Negligible smoke obscuration. Class O / low risk fire rating. No requirement for a vapour control layer. Quick response floor heating – prevents heat loss through ‘heat sump’. Minimises the cost of related items – soil removal, DPMs, service connections. Front Face of board is Foil Faced. Reverse Face of the board is Glass Tissue Core – Premium performance lower-lambda rigid thermoset phenolic insulation manufactured with a blowing agent that has zero Ozone Depletion Potential (ODP) and low Global Warming Potential (GWP)

Celotex TB4000 Range Insulation Board 1200mm x 2400mm x 75mm

TB4000 is targeted at cut-to-fit applications between rafters or joists and enables users to achieve lower U-values with a single layer of insulation than has previously been possible. It is also appropriate for use in floors and walls. With low emissivity foil facings, TB4030 is manufactured from rigid polyisocyanurate (PIR) using a blend of blowing agents that have zero ozone depletion potential (zero ODP) and low global warming potential (GWP).
