Insulation board KAN-therm EPS100 038 (PS20) sheet 5 m² – 30 mm with laminated foil

Thermal insulation sheet KAN-therm EPS100 038 (PS20) is a flat expanded polystyrene panel supplied as a 1 × 5 m sheet covering 5 m², with a thickness of 30 mm and a laminated foil surface. The product combines EPS thermal insulation with a vapor-resistant laminated facing to provide improved moisture control and a smooth surface suitable for use under screeds, floating floors or as part of wall and ceiling insulation systems. Declared thermal conductivity corresponds to class 038 and compressive strength to PS20, suitable for light to medium floor loading and general thermal insulation tasks.

Advantages

The laminated foil surface reduces water vapour penetration and simplifies integration with vapour barriers or floor screed layers, while the EPS core delivers consistent thermal performance and low weight. The large 1 × 5 m sheet format allows quick coverage of larger areas with fewer joints, and the 30 mm thickness provides a balance between thermal resistance and build-up height. The PS20 compressive strength ensures the board withstands typical installation loads encountered in renovation and underfloor heating assemblies.

Suitable for

• Underfloor heating systems beneath screed or floating floors
• Thermal insulation of floors in renovations and new builds
• Wall and ceiling insulation where a vapour-resistant facing is required
• Applications needing lightweight, easy-to-cut insulation panels

How to use

Place the KAN-therm EPS100 038 (PS20) sheets on a clean, level substrate, ensuring the laminated foil faces the wet screed or the direction required for vapour control. Trim panels to fit edges and around penetrations using a sharp knife or saw appropriate for polystyrene. Butt joints tightly and, where necessary, seal seams with compatible tape or adhesive to maintain vapor resistance. When used with underfloor heating systems, follow the heating system manufacturer's guidelines for screed thickness and installation sequence to ensure correct embedment and thermal performance.

Usage recommendations

Store sheets flat, protected from direct sunlight and prolonged exposure to oils, solvents or open flame. Avoid compressive point loads during and after installation; ensure that any mechanical loads are distributed or supported. For applications requiring higher compressive strength or different thermal resistance, select alternative thicknesses or EPS grades compatible with the project's structural and thermal requirements.
