100mm Recticel Eurowall® Partial Fill Cavity Insulation Board 1200mm x 450mm - 5.40m2 per pack
The 100mm Recticel Eurowall® Cavity Insulation Board is a high-performance rigid PIR board for partial fill cavity wall insulation in masonry construction. It is fixed against the inner leaf with a clear residual cavity left to the outer leaf, and suits walls designed around a wider cavity where a high level of thermal resistance is needed from the board layer.
At 100mm the board provides a thermal resistance (RD) of 4.50 m²K/W with a declared thermal conductivity of 0.022 W/mK. Because it is a deep board, the cavity has to be wide enough to take the 100mm board and still leave the clear residual gap, so the cavity width and overall wall build-up should be confirmed at design stage before specifying.
Both faces carry a gas diffusion tight multilayer foil with a low-emissivity grid pattern (ε 0.05), which adds thermal resistance across the residual cavity when installed in a non-ventilated build-up. The straight edges on all four sides let boards butt closely so gaps and thermal bridging through the insulation layer are kept down.
The closed-cell PIR core absorbs little moisture, so the board holds its thermal performance over the life of the wall. It can be cut to size on site with a fine-toothed saw or sharp knife and suits both new build and renovation work. Install in line with the latest Recticel technical guidance, project specification and relevant building requirements.
Key Benefits of 100mm Eurowall® Cavity:
- High-performance rigid PIR partial fill cavity board with 4.50 m²K/W thermal resistance at 100mm
- Low 0.022 W/mK thermal conductivity for strong performance per millimetre of thickness
- High board-layer resistance suited to wider-cavity builds in a partial fill detail
- Foil facing on both sides (ε 0.05), adding resistance across the residual cavity in a non-ventilated build-up
- Straight edges on all four sides for close-butted joints and reduced thermal bridging
- Closed-cell core with low moisture absorption to maintain long-term performance
- Supplied 10 boards per pack, covering 5.40m²
- Manufactured in the UK to EN 13165:2012 + A2:2016
Recticel Eurowall® Cavity Insulation Board provides a partial fill insulation option for masonry cavity walls where thermal performance, board fit and long-term moisture resistance matter.
