About Our Foil Faced PIR Insulation & Polystyrene Sheets

We stock foil faced PIR insulation and polystyrene sheets that are used for wall cavities, roofs, floors, and general building projects.

These rigid insulation boards deliver high thermal performance at minimal thickness. This means that they are ideal for retrofits, new builds, and extensions where space is at a premium. Foil facings provide excellent vapour resistance and reflect radiant heat, which boosts overall efficiency.

Our range includes options from trusted manufacturers like Recticel, Ecotherm, and multifoil alternatives, covering everything from 25mm PIR insulation boards to 150mm PIR insulation boards.

About Our PIR Insulation Boards & Polystyrene Sheets

We offer full fill cavity boards, tongue and groove panels for walls, and flat boards suitable for pitched and flat roofs. Foil faced PIR insulation boards provide superior thermal values compared to traditional mineral wool or expanded polystyrene, meaning you can achieve Building Regulations compliance using thinner material. This is particularly useful in loft conversions, garage conversions, or any setting in which head height matters.

Polystyrene insulation sheets offer a lightweight, moisture resistant option for below-ground applications, under concrete slabs, or as an external wall insulation substrate.

We work closely with Recticel to supply their Eurothane GP and Eurowall ranges, both offering PEFC certification for sustainable sourcing. Ecotherm's Eco Cavity boards are designed specifically for full fill applications, eliminating cold bridging in narrow cavities.

For detailed work around openings, cavity closers from Thermo Loc and XRM provide neat thermal continuity without excessive material waste. Multifoil products like YBS Superquilt and Breath R Quilt complement rigid boards in warm roof builds or timber frame constructions, adding flexibility to your specification. To find more options, see our full selection of insulation.
