Celotex SL5000 is a premium performance concrete soffit liner solution, utilising thermal performance properties of Celotex PIR insulation bonded with calcium silicate to provide additional fire performance. Featuring a super low lambda value of 0.021 W/mK, SL5000 ensures Regulatory compliance is achieved with minimal insulation thicknesses.

• Board size: 1200 x 2400mm
• Thickness : (Currently Suspended) 86 - 106mm
• Lambda: 0.021 W/mK
• Facer: 6mm calcium silicate bonded to foil facer

Celotex SL5000 provides on-site benefits too, significantly reducing installation times due to the insulation and calcium silicate being supplied as one product. Delivering greater impact resistance compared to exposed insulation systems, SL5000 provides a decorative finish with no need for on-site decorating. SL5000 is supported by the Celotex Technical Centre and Thermal Bridging Models.
