The round-number 100mm depth carries the highest single-board thermal resistance in the range, which is why it is so often the board reached for first on \u003ca href=\"https:\/\/www.insulationuk.co.uk\/collections\/concrete-floor-insulation\"\u003esolid floors\u003c\/a\u003e, \u003ca href=\"https:\/\/www.insulationuk.co.uk\/collections\/underfloor-heating-insulation\"\u003eunderfloor heating\u003c\/a\u003e and standard build-ups.

With a declared thermal conductivity of 0.022 W\/mK and an R-value (thermal resistance) of 4.50 m²K\/W, 100mm GA4100 delivers the strongest single-layer figure in the GA4000 range, at around 4.15 kg per square metre. The rigid PIR core is faced both sides with a low-emissivity aluminium foil that lifts performance against a sealed cavity air space, and the square edges butt together for a continuous, tight-jointed layer.\u003c\/p\u003e\n\u003cp\u003eOn solid ground floors, 100mm GA4100 is typically laid over the damp-proof membrane beneath the screed, where it commonly meets the Part L floor target, and it suits underfloor heating, beam-and-block, oversite and suspended timber floors equally well. The same board is used as a single layer in pitched roofs between or under rafters, in timber-frame walls and internal dry lining, and in flat-roof build-ups within the GA4000 range's scope. 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.

With a thermal conductivity of 0.022 W\/mK the board provides a thermal resistance of approximately 4.55 m²K\/W, suited to applications where a demanding U-value target needs to be met within a workable build-up depth. The foil facing acts as a vapour control layer and the square edge profile keeps joints tight, limiting thermal bridging.

As the entry thickness in the STARflex Ultra 42 range, the 100mm roll is typically used as the first, base layer of a loft build-up, ready to be cross-laid with a thicker roll on top to reach full recommended depth.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eEach roll measures 1140mm wide by 9.5m long, covering 10.83m² per roll, and is supplied as a single roll per pack. Thermal conductivity is 0.042 W\/mK, giving a thermal resistance of 2.38 m²K\/W at 100mm thickness, and the product carries a Euroclass A1 non-combustible reaction-to-fire classification, the highest rating available, meaning it does not burn. Between the thermal performance and the fire rating, STARflex Loft Roll Ultra 42 offers a solid, straightforward specification at a competitive price point for anyone building up loft insulation depth.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eSTARflex Loft Roll Ultra 42 is manufactured from more than 80% recycled glass content and is designed not to degrade, decompose or become mouldy over time, so once it's installed it's built to last the lifetime of the building rather than needing replacing down the line. The roll is also perforated so it can be split into two 570mm-wide strips or three 380mm-wide strips, giving a neater fit between standard ceiling joist centres with less waste. It's supplied in Hyperpack palletised packaging, which allows more product to be loaded per pallet, keeps stocking costs down, and means it can be stored outdoors if site space is tight.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eIt's suited to both new build and renovation loft insulation work, wherever a base layer is needed at ceiling level in a cold pitched roof. Install in line with the latest ODE technical guidance and the project specification, laying the roll between the joists before adding a second, thicker roll cross-laid on top to build up total depth and improve thermal performance. Used as intended, it offers a straightforward, cost-effective route to reducing loft heat loss.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eKey Benefits of ODE STARflex Loft Roll Ultra 42:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul dir=\"ltr\"\u003e\n\u003cli\u003eThermal conductivity of 0.042 W\/mK for dependable loft insulation performance\u003c\/li\u003e\n\u003cli\u003eThermal resistance (R-value) of 2.38 m²K\/W at 100mm thickness\u003c\/li\u003e\n\u003cli\u003eEuroclass A1 non-combustible reaction to fire, the highest classification available\u003c\/li\u003e\n\u003cli\u003e10.83m² coverage per roll, supplied one roll per pack\u003c\/li\u003e\n\u003cli\u003ePerforated to split into two 570mm-wide or three 380mm-wide strips, for a neat fit with minimal wastage\u003c\/li\u003e\n\u003cli\u003eManufactured from more than 80% recycled glass content\u003c\/li\u003e\n\u003cli\u003eDoes not degrade, decompose or become mouldy over time\u003c\/li\u003e\n\u003cli\u003eBRE Green Guide rating of A+\u003c\/li\u003e\n\u003cli\u003eHyperpack palletised packaging: more product per pallet, lower stocking costs, can be stored outdoors\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\u003eDimensions:\u003c\/strong\u003e 1140mm wide x 9.5m long, 100mm thick, 10.83m² coverage per roll, sold as one roll per pack\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThermal resistance:\u003c\/strong\u003e 2.38 m²K\/W, calculated from thickness and thermal conductivity rather than separately stated by the manufacturer\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePacks per pallet:\u003c\/strong\u003e 24; coverage per pallet: 259.92m²\u003c\/li\u003e\n\u003cli\u003eAlways check the latest ODE datasheet and confirm total loft depth against current Building Regulations guidance before ordering\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp dir=\"ltr\"\u003eA dependable, competitively priced base layer for cold loft insulation, 100mm STARflex Loft Roll Ultra 42 makes it easy to start a build-up the right way and add depth on top when you're ready.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eBrowse the full \u003ca href=\"https:\/\/www.insulationuk.co.uk\/collections\/loft-roll-insulation\"\u003eloft roll range\u003c\/a\u003e for top-up thicknesses to complete the build-up.\u003c\/p\u003e","brand":"ODE","offers":[{"title":"Default Title","offer_id":60461371916622,"sku":"BM06701","price":23.52,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0894\/1083\/0670\/files\/ode-100mm-ode-starflex-loft-roll-ultra-brown-hp-42-9-5m-x-1-14m-bm06701-mineral-fibre-insulation-1255990127.png?v=1787851157"}],"url":"https:\/\/www.insulationuk.co.uk\/collections\/100mm-wall-insulation.oembed?page=3","provider":"Insulation UK","version":"1.0","type":"link"}
