Thermaroof TR26 is a rigid thermoset insulation core that is perfect for insulating flat roofs waterproofed with mechanically fixed single-ply waterproofing in a variety of new build and refurbishment projects. This board provides high performance and is fibre-free core with a thermal conductivity of 0.022 W/mK, as well as a resistance to the passage of water vapour.
Featuring low emissivity composite foil facings on both sides, this board can be easily integrated with most mechanically fixed single-ply waterproofing systems and green roof systems. Available with FM Approval to FM 4470 – search ‘Kingspan Therma’ on the FM Approvals website for conditions of approval.
