90mm EPS External Wall Insulation 1200mm x 600mm - 0.72m2 per sheet
Sold in packs of 13
90mm EPS External Wall Insulation is a graphite-enhanced expanded polystyrene (EPS) board for external wall insulation (EWI) systems, aimed at solid-wall properties being brought up to current thermal standards. At 90mm it sits in the retrofit band where a single layer can carry a masonry wall to a Building Regulation U-value, which is why it is a common specification on whole-house EWI upgrades and PAS 2035 retrofit work.
Each board measures 1200mm x 600mm and is supplied 13 boards to a pack for 9.36m² of coverage. It carries a declared thermal conductivity of 0.030 W/mK and a thermal resistance of 3.00 m²K/W*, and in SPI's own example build-up the 90mm board takes a solid brickwork wall to a 0.30 W/m²K U-value in England and Wales, a figure that depends on the full wall construction rather than the board alone.
Graphite EPS is a low-density material, so even at 90mm the board stays light in the hand. It can be lifted, offered up and trimmed with a fine-tooth saw or hot-wire cutter without specialist tools, which keeps a deeper build-up moving on site and puts little extra load on the substrate and the fixings holding it. That counts for more as the range climbs into its thicker boards, where weight and handling start to shape the day's work.
90mm EPS External Wall Insulation is fitted as part of a complete EWI system: bonded to the wall with an adhesive mortar, secured with mechanical fixings, then rasped level, reinforced with mesh in a basecoat and finished with render. It suits solid brickwork, timber frame and steel frame walls on buildings up to 18m, and should be installed to the system provider's instructions, the Stylite EWI datasheet and the project specification. At 90mm the build-up is deeper than the slim upgrade boards, so reveals, sills, verges and beads need setting out to take the added thickness. Reaction to fire, durability and weathering are properties of the finished system rather than the insulation board on its own.
Key Benefits of 90mm EPS External Wall Insulation:
- 90mm graphite-enhanced expanded polystyrene (EPS) board for external wall insulation systems.
- Declared thermal conductivity of 0.030 W/mK, ahead of standard white EPS at the same thickness.
- Thermal resistance of 3.00 m²K/W* for the 90mm board.
- Specified by SPI to reach a 0.30 W/m²K U-value in an England and Wales brickwork refurbishment build-up.
- Single-layer thickness for many solid-wall retrofit and PAS 2035 upgrades.
- Suitable for wall applications up to 18m.
- Compatible with adhesive and mechanically fixed EWI systems.
- Suitable for solid brickwork, timber frame and steel frame constructions.
- Light for its depth and cut on site with a fine-tooth saw or hot-wire cutter, with no specialist tools required.
- 100% recyclable, with zero GWP and no CFCs, HCFCs or HFCs.
Good to know:
- Grade: PlusTherm 70: thermal conductivity 0.030 W/mK; compressive strength 70 kPa at 10%.
- Board size 1200mm x 600mm (0.72m²): thickness 90mm; 13 boards per pack (9.36m²).
- Manufactured to BS EN 13163:2012+A2:2016: produced under ISO 9001 and ISO 14001 certified management systems.
- PVC cables must be protected within a suitable conduit to prevent plasticiser migration.
- Store flat on a firm, level base, protected from sunlight and UV exposure.
- Always refer to the Stylite EWI datasheet and system provider's guidance before installing.
For a solid-wall retrofit that has to hit its target U-value in one layer, 90mm graphite EPS carries the performance without the price of a premium board.
