It is the thinnest board in the K103 range, and at 25mm it is typically specified where floor depth is limited: as a thin upgrade or topping-up layer, in garage conversions, as part of a multi-layer build-up, or cut down to form the perimeter upstand strips that reduce heat loss at the floor edge.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eEach sheet measures 2400mm x 1200mm and covers 2.88m². The phenolic core has a thermal conductivity of 0.019 W\/mK, one of the lowest figures available in rigid floor insulation, giving the 25mm board a thermal resistance of 1.30 m²K\/W. Its compressive strength of 120 kPa allows it to carry screed and normal floor loads, and it is faced on both sides with a glass tissue based facing, autohesively bonded to the core during manufacture. Because phenolic reaches a given thermal resistance in less thickness than higher-lambda materials, the 25mm board adds insulation where there is little room to spare.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eThe glass tissue facing keeps the board straightforward to handle and to cut cleanly, either with a fine-toothed saw or by scoring and snapping. Single sheets can therefore be trimmed accurately to fit between joists or sized into perimeter strips with minimal waste, which matters most on smaller areas and finishing work where offcuts add up.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e25mm Kooltherm K103 is used in beam and dense block ground floors, suspended timber ground floors and solid concrete ground floors, installed below the screed, below the slab or between the joists depending on the construction.
