Kingspan 110mm Thermaroof TR26 PIR Insulation Board | 2400mm x 1200mm | 8.64m2 | Pack of 3 | UK

Kingspan Thermaroof TR26 110 mm Flat Roof PIR Insulation Board (2400 mm × 1200 mm, Pack off 3 - 8.64 m²) Product Overview Kingspan Thermaroof TR26 110 mm (2400 mm × 1200 mm) Flat Roof PIR Insulation Board is a high‑performance rigid thermoset polyisocyanurate (PIR) insulation board designed for flat roof applications (new‑build or refurbishment) using mechanically‑fixed single‑ply or similar waterproofing systems. The large 2400 × 1200 mm board format and enhanced insulating thickness provide a dependable thermal layer in warm‑roof assemblies. The product has a declared thermal conductivity of 0.022 W/m·K. Key Features & Benefits Rigid PIR core with thermal conductivity of 0.022 W/m·K across the TR26 range. Large board size 2400 × 1200 mm reduces joints, minimises installation time and helps reduce potential thermal bridging. Compatible with most mechanically‑fixed single‑ply waterproofing systems and green roof applications. Closed‑cell fibre‑free PIR core with low‑emissivity composite foil facings on both sides which resist water‑vapour transmission. High compressive strength (CS(10Y)150) meaning the board can endure roof loads and wind uplift when properly fixed. Suitable for fast‑track programmes thanks to large board format and ease of handling. Manufactured under quality and environmental management systems (ISO 9001, ISO 14001, ISO 45001, ISO 50001).   Applications / Typical Uses Ideal for insulating flat roofs in residential, commercial, industrial and public buildings where higher thermal performance is required and board thickness is moderate. Designed for use under mechanically‑fixed single‑ply waterproof membranes or similar warm roof waterproofing systems. Suitable for both new‑build and refurbishment roof projects where board dimension (2400×1200 mm) and thickness (110 mm) are appropriate. Appropriate for installation over concrete decks, metal decks or timber decks (subject to correct design detail, vapour control and waterproofing).   Installation & Handling Store the boards flat on a clean, dry, level surface and protect from exposure to weather or site moisture before installation. Do not use boards that have become wet or show signs of damage. Lay the boards staggered (“break‑bonded”) so that long‑edge joints do not line up with adjacent rows; ensure joints are lightly butted together. Fix boards either mechanically or via adhesive as specified for the roof deck and waterproofing system design. Ensure a suitable vapour control layer or sealed deck is in place beneath the insulation where required and that a condensation risk analysis is undertaken for each roof build‑up. After insulation installation, proceed with the waterproofing membrane installation per the membrane manufacturer’s instructions — ensure compatibility with the insulation board. Ensure continuity of insulation at parapets, upstands, penetrations to minimise heat loss and thermal bridging. Due to the large board size (2400 × 1200 mm) and thickness (110 mm), handle carefully during transit and installation to avoid damage to board edges or facings.   Compliance & Certification Manufactured to the standard BS EN 13165:2012   A2:2016 for factory‑made rigid PIR insulation boards.
