Isofloor® panels are rigid, high-density moulded expanded polystyrene (EPS) boards with high compressive strength and excellent thermal insulation (low thermal conductivity). They’re designed as the base layer for plastic underfloor heating pipes. Isofloor® is manufactured to EN 13163:2015 under ISO 9001:2015 certified production and carries the CE mark.
- Two strength grades: 150 and 200 kPa compressive strength (at 10% deformation)
- PLUS version: available with or without a vapour barrier made of high-impact polystyrene film (HIPS)
- Panel size: 1.20 m × 0.90 m
- Two pipe spacings: 50 mm or 75 mm pitch
- 5 mm studs hold the pipe above the insulation, so the screed fully surrounds the pipes
- Interlocking edges join the panels into one continuous insulation layer without gaps or thermal bridges
- Supplied with a polyethylene foam perimeter strip and expansion joint strip
Installation tip: leave a gap of at least 5 mm between the panels and the surrounding walls, filled with a compressible material such as polyethylene foam or low-density EPS. If the insulation design calls for more thickness, lay an additional EPS layer underneath Isofloor®.
