It goes between studs in partitions and external walls, between joists in floors, and between rafters in roofs — and it stays put without slumping, cutting or fixing. The slab is made from natural volcanic rock spun into stone wool fibres, and it is manufactured with a flexible edge along one side that compresses on installation and then expands to grip the frame tightly from within.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eThis is the 100mm slab in the 400mm width — one of the most versatile thicknesses in the Flexi range. It is the depth called for in suspended timber ground floor applications, one-hour fire upgrade floor constructions, Approved Document E separating floor systems and Approved Document E internal domestic floor systems. The same slab covers all of those applications, which makes it a practical product to have on site when multiple build-ups are involved.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eThe slab achieves a thermal conductivity (lambda) of 0.038 W\/mK and a Euroclass A1 reaction-to-fire classification — fully non-combustible. It has been tested to BS 476: Part 21 and confirmed to achieve one-hour fire resistance in existing timber floor constructions when installed correctly. In separating floor builds using ROCKWOOL RockFloor resilient layer, 100mm Flexi contributes to achieving Rw 54dB airborne and Lnw 54dB impact performance to Part E Section 3.

Install it in line with the latest Celotex technical guidance, the project specification and current Building Regulations, including fire requirements and the height limit on external wall use.

It is specified in commercial, industrial and cold storage areas subject to vehicular traffic and point loading, and in basement floor, basement wall and inverted flat roof build-ups where the insulation sits in a wet or below-ground environment.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eEach board measures 1250mm x 600mm x 100mm and gives 0.75m² of coverage, supplied four boards to a pack for 3.00m² per pack. Packs are stacked twelve to a pallet, giving 36.00m² per pallet and a board weight of approximately 3kg, so a full pack lifts comfortably by hand on site. The declared thermal conductivity at 100mm is 0.033 W\/mK, giving a thermal resistance of 2.75 m²K\/W, and compressive strength is rated at 300 kPa at 10% compression to EN 826:2013.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eThe rebated edge profile runs on all four sides of the board. Across a large floor plate this matters more than it sounds: rebated joints overlap rather than butt, closing off the straight-through gaps that square-edged boards leave and helping to limit thermal bridging along every joint line in the layer. Closed-cell extruded polystyrene also brings water performance that open-cell and faced boards cannot match, with long-term water absorption by total immersion classified WL(T)0,7, absorption by diffusion at WD(V)1 for the 100–300mm thickness band, and freeze-thaw resistance classified FTCD1. That combination is what allows the board to be used below the waterproofing layer in an inverted roof and below ground in basement construction without progressive loss of thermal performance.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eIn use, 100mm XPS 300 is laid over a suitably prepared and level substrate in solid ground floor, basement and inverted roof build-ups, and should be installed in line with the latest Unilin Insulation technical guidance, the project specification and the relevant building regulations. Boards cut cleanly with a fine-toothed saw or sharp knife and can be worked in cold or wet weather without deterioration, which keeps programme moving on winter groundworks. Where the board sits under a screed or slab, the specifier should confirm the loading regime, damp proof membrane position and any separating layer required by the design. Compressive creep is declared CC(2\/1,5\/50)130 across the 60–120mm band, giving the design team a stated long-term deformation figure to work to rather than a headline short-term number alone.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eKey Benefits of Unilin XPS 300:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul dir=\"ltr\"\u003e\n\u003cli\u003e100mm rigid extruded polystyrene insulation board for high-load floor, basement and inverted roof applications.\u003c\/li\u003e\n\u003cli\u003e300 kPa compressive strength at 10% compression, tested to EN 826:2013, for trafficked and heavily loaded floors.\u003c\/li\u003e\n\u003cli\u003eThermal conductivity of 0.033 W\/mK at 100mm and thermal resistance of 2.75 m²K\/W.\u003c\/li\u003e\n\u003cli\u003eRebated edge on all four sides to close joint lines and help limit thermal bridging across the insulation layer.\u003c\/li\u003e\n\u003cli\u003eClosed-cell structure with WL(T)0,7 long-term water absorption by total immersion for wet and below-ground use.\u003c\/li\u003e\n\u003cli\u003eFreeze-thaw resistance classified FTCD1, supporting use below waterproofing in inverted roof build-ups.\u003c\/li\u003e\n\u003cli\u003eCompressive creep declared CC(2\/1,5\/50)130 for the 60–120mm band, giving a stated long-term loading figure.\u003c\/li\u003e\n\u003cli\u003eManufactured to EN 13164:2012+A1:2015 under ISO 9001 and ISO 14001 certified management systems.\u003c\/li\u003e\n\u003cli\u003eSupplied 4 boards per pack covering 3.00m², with 12 packs per pallet covering 36.00m².\u003c\/li\u003e\n\u003cli\u003eApproximately 3kg per board, keeping handling straightforward on site.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eGood to Know:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul dir=\"ltr\"\u003e\n\u003cli\u003e\n\u003cstrong\u003eReaction to fire is Euroclass E\u003c\/strong\u003e to EN 13501-1:2018.
