Thermano Compact PIR insulation board, 40 mm – 1200 × 600 mm

Rigid PIR boards provide high thermal resistance in a thin layer. That makes them useful where space is limited, for example when renovating a roof, insulating beneath a floor or fitting insulation into an existing wall build-up. The boards are light and easy to cut. Different facings are available to suit different construction systems.

The PIR core has low thermal conductivity. A designer can often achieve the required thermal resistance with a thinner layer than with many standard grades of expanded polystyrene or mineral wool. This helps preserve headroom, match adjacent floor levels or fit insulation at the eaves. A well-insulated building loses less heat in winter and admits less heat in summer, improving comfort and helping control running costs.

The rigid, relatively light boards can be cut to the shape of the surface. Machined edge profiles, where specified, help adjacent boards fit closely. A suitable build-up and carefully finished joints reduce thermal bridging. Choose the facing for the application: a membrane roof, a rendered façade and a ceiling in an agricultural building may each require a different product.

PIR is used in flat and pitched roofs, ceilings and floors. Above-rafter insulation can form a continuous layer over a timber roof structure. Floor boards must suit the expected loads; façade boards must be compatible with the specified finish. AGRO boards with suitable facings are intended for selected agricultural and utility buildings.

Compare thickness, declared thermal performance, strength and compatibility with the surrounding materials. A PIR board does not automatically replace waterproofing or a required vapour control layer. The complete assembly and correct installation determine the result. Accessories for joints and edge details can be ordered alongside the boards for the area you plan to insulate.

In refurbishment work, high thermal resistance in a thin layer makes it easier to tie a new floor level or roof detail into the existing building. This can resolve a local insulation problem without increasing the depth of the entire assembly.

SteelProfil offers first- and second-grade PIR insulation boards and selected outlet lots. Some products are available from stock, which can help when starting a job or ordering extra boards. Promotions and outlet pricing offer options for a limited budget. With second-grade material, check the condition of the actual lot against the needs of the project.
