50mm EPS External Wall Insulation 1200mm x 600mm - 0.72m2 per sheet
Sold in packs of 24
50mm EPS External Wall Insulation is a graphite-enhanced expanded polystyrene (EPS) board and the mid-range workhorse of the PlusTherm line. It is the thickness solid-wall retrofits reach for most often: a genuine thermal upgrade that stops short of a full field depth, suited to houses and smaller commercial walls where a balanced build-up matters.
Each board measures 1200mm x 600mm and covers 0.72m², supplied 24 boards to a pack for 17.28m² of coverage. It carries a declared thermal conductivity of 0.030 W/mK, a PlusTherm 70 grade with 70 kPa compressive strength at 10% deformation, and a calculated thermal resistance of 1.65 m²K/W* at 50mm. The graphite-enhanced core delivers that resistance in less depth than standard white EPS, which keeps the wall's projection in check.
At 1200mm x 600mm, each board covers 0.72m², a larger sheet than many EPS boards on the market. Across a full elevation that means fewer boards to fix and fewer joints between them, so the field goes up faster and there are fewer board junctions for heat to track along. Set out with staggered, close-butted joints, the insulation layer stays continuous behind the render.
50mm EPS External Wall Insulation is bonded to masonry or timber-backed substrates with adhesive, mechanically fixed, or both, then rasped flat and finished within a designed render system, installed to SPI's guidance and the render system provider's specification. It suits solid brickwork, timber frame and steel frame construction on wall applications up to 18m. As a common upgrade thickness it pairs cleanly with standard EWI ancillaries and thin-coat renders, though where the target is a full regulatory upgrade a thicker board is often specified. As with all EPS, the finished fire performance and durability belong to the complete system, not the board alone.
Key Benefits of 50mm EPS External Wall Insulation:
- 50mm graphite-enhanced EPS board, the popular mid-range thickness for solid-wall upgrades.
- Calculated thermal resistance of 1.65 m²K/W* at 50mm.
- Declared thermal conductivity of 0.030 W/mK, reaching that resistance in less depth than standard white EPS.
- Large 1200mm x 600mm board (0.72m²), covering ground with fewer joints across the wall.
- Insulates the external face of the wall, helping to reduce condensation risk.
- PlusTherm 70 grade with 70 kPa compressive strength at 10% deformation.
- Compatible with adhesive and mechanically fixed EWI systems and thin-coat renders.
- Suitable for solid brickwork, timber frame and steel frame construction.
- Reaction to fire Euroclass E to BS EN 13501-1, with no loss of thermal performance over time.
- 100% recyclable with a BRE Green Guide rating A+, and no CFCs, HCFCs or HFCs (zero GWP).
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 50mm; 24 boards per pack (17.28m²).
- Manufactured to BS EN 13163:2012+A2:2016: ISO 9001 and ISO 14001 certified.
- 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.
When a solid wall needs a real upgrade and a build-up that still behaves itself, 50mm EPS External Wall Insulation is the thickness most projects settle on for good reason.
