Built from a rigid polyisocyanurate (PIR) core with gas-tight foil facings, it suits pitched roofs, timber and metal framed walls, ceilings and floors, and is a common choice as insulated sheathing on framed-wall builds.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eEach 2400mm x 1200mm board covers 2.88m² and combines a 0.022 W\/mK thermal conductivity with a thermal resistance of around 2.70 m²K\/W. Sitting in the range's higher strength tier, it carries a compressive strength of at least 140 kPa, so it copes with the loadings in screeded and boarded floors as readily as it performs in walls and roofs.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eThe low-emissivity foil on both faces gives high resistance to moisture vapour, so the board keeps its thermal performance rather than absorbing water and sagging over time. Square edges let boards butt up tightly across the build, and with joints taped or filled as specified, the insulation layer stays continuous and thermal bridging is minimised.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eIn framed walls it can be fitted between studs or over them as insulated sheathing; elsewhere it goes between and over joists, beneath screeds, and between rafters in pitched roofs. It is compatible with both wet and electric underfloor heating. Install it to the current Recticel technical guidance, the relevant specification guide and the project specification.

at one of the construction industry's standard insulation thicknesses, which makes it a straightforward choice wherever a specification is written around a 75mm PIR board. Built from a rigid polyisocyanurate (PIR) core with low-emissivity foil facings on both sides, it is manufactured in the UK and suits pitched roofs, framed walls, floors, ceilings and lofts.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eEach 2400mm x 1200mm board covers 2.88m², weighs around 2.8 kg\/m² and has a density of roughly 31 kg\/m³. With a thermal conductivity of 0.022 W\/mK it delivers a thermal resistance of around 3.40 m²K\/W from a single 75mm layer, while a compressive strength of at least 140 kPa supports its use under screeded and boarded floors.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eAs a standard 75mm module it sits alongside other 75mm PIR boards, so it drops into build-ups designed around that depth without redesign. The low-emissivity foil facings keep moisture vapour resistance high so the board holds its performance over time, and the square edges butt up tightly: tape or fill the joints as specified and the insulation layer stays continuous, limiting thermal bridging.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eIt works across new build and refurbishment, covering ground floors (including under screed and over underfloor heating), timber and metal framed walls (between studs or as sheathing), pitched roofs (between or over rafters), and ceilings and lofts. Where a single layer is not enough, 75mm boards can be doubled with joints staggered between layers.

a rigid polyisocyanurate (PIR) insulation board with a closed-cell core, faced on both sides with a gas diffusion tight, low-emissivity multilayer foil. It is a general purpose board for pitched roofs, timber and metal framed walls, and floors, including build-ups that incorporate underfloor heating, and it suits projects that need strong thermal performance from a single layer.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eEach board measures 2400mm x 1200mm and is supplied as a single sheet covering 2.88m². At 110mm it delivers a declared thermal resistance (R-value) of 5.00 m²K\/W from a declared thermal conductivity of 0.022 W\/mK, a useful step up from the 100mm board for projects pushing towards lower U-value targets without moving to two layers.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eThe straight edges butt tightly together across a run, helping to keep joints closed and limit thermal bridging through the insulation layer, while the printed grid on both faces guides accurate cutting on site. The low-emissivity foil facings work alongside an adjacent air space to support the board's thermal performance, and the closed-cell core resists moisture pick-up and holds its shape over time.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eIn floors, the board can be laid over a damp-proof membrane in solid and suspended constructions and to upgrade existing slabs, and is compatible with underfloor heating; in pitched roofs it can be fitted between, over or below the rafters; in framed walls it sits between studs or as a continuous lining, and it can line solid masonry walls internally. Install in line with the latest Recticel technical guidance and the project specification, and finish internal walls with plasterboard rather than plaster or paint applied directly. Suitable for new build and refurbishment, 110mm Eurothane GP raises thermal performance while keeping construction depth in check.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words

Where a build-up has to go deeper still, a second board is added with its joints offset. Fit it in line with Recticel's current technical guidance and the project specification, and bring internal walls to a finish with plasterboard rather than working plaster or paint straight onto the foil.

It is used in pitched and flat roofs, between and below timber joists, concrete slab floors, and framed or plasterboard-lined walls. With a thermal conductivity of 0.022 W\/mK, the 150mm thickness gives a thermal resistance of approximately 6.82 m²K\/W, often removing the need to layer thinner boards. The foil facing serves as a vapour control layer and the square edge profile keeps joints tight, limiting thermal bridging. The board remains dimensionally stable under temperature, humidity, moisture and UV exposure, across commercial and domestic, new build and refurbishment projects.
