Novecrafto Men's 38mm EPS Underfloor Heating Castellated Insulation Board 145 x 85 cm in Black Novecrafto Black 145 x 85 cm

This 38mm castellated underfloor heating insulation board is designed for warm water underfloor heating systems in screeded floors. Each 145 × 85 cm panel (1.23 m²) combines rigid EPS foam insulation with a moulded surface that locks 14-17 mm pipes securely into place. The 20 mm polystyrene sheet layer reduces downward heat loss, while the castellated design ensures even pipe spacing. Interlocking edges create seamless coverage, and the strong foam underlay resists compression under screed. Suitable for new builds or refurbishments, these insulation panels for heated floors improve energy efficiency, deliver consistent warmth, and act as a reliable floor insulation board for heating.
