The Recticel Powerdeck F Flat Roof Insulation Board (600mm x 1200mm x 140mm) is a high-performance, rigid Polyisocyanurate (PIR) insulation board engineered specifically for use in flat roofing systems. Featuring a substantial 140mm closed-cell PIR core, it delivers exceptionally low thermal conductivity (high thermal resistance), making it an ideal solution for warm roof constructions aimed at meeting ultra-low U-value targets in modern building regulations.
 
Designed with tough, multi-layer fleece-faced surfaces on both sides, this board offers high compatibility with a wide range of flat roof waterproofing membranes, including single-ply membranes, torch-on bitumen felt systems, and cold liquid-applied waterproofing. Its high compressive strength ensures excellent resistance to foot traffic and installation loads during construction and maintenance.
 
Supplied in a compact, easy-to-handle 1200mm x 600mm panel format, it allows for effortless maneuverability across roof decks and scaffolding, minimizing installation fatigue while facilitating precise laying and staggered joint configurations. It is rot-proof, dimensionally stable, and chemically resistant, providing a durable, long-term thermal barrier for commercial, industrial, and residential flat roofing projects.
