SOPREMA TMS rigid floor insulation, 1,200 × 1,000 × 47 mm, second grade

Space for insulation is often tight when renovating a roof or floor. Headroom, adjacent floor levels and the roof build-up set practical limits. With their strong thermal performance, PIR boards can provide the required insulation in the depth available. SteelProfil offers boards for different parts of the building and can help you select one.

Rigid polyisocyanurate foam allows thermal performance and space to be considered together. In a loft, the limit may be usable headroom. On a terrace, it may be the door threshold, and in a floor refurbishment, the level of the next room. Select the insulation thickness as part of the complete build-up.

PIR boards differ in facing, edge profile and intended use. Choose a roof, floor, wall or specialist board by its loads, fixings and finish. This helps the installer use a board intended for that part of the job. On an extension, it also helps the new insulation meet the existing layers.

Rigid boards are easy to lay on a prepared substrate and to cut at edges. Edge profiles help adjacent boards meet, and suitable joint seals maintain continuity. This matters on a large roof slope just as it does in a small room with several corners.

On a pitched roof, PIR may be specified above the rafters or in another designed arrangement. Suitable grades are also used in flat roofs and floors. Planning the insulation with the whole assembly lets you choose compatible materials for the following stages.

SteelProfil offers first- and second-grade boards, with selected sizes in stock. Check the edges, facings and dimensions of any second-grade lot. We can help assess where you can use it, particularly if the design calls for several short sections.

Specify the location as well as the area. A rendered wall calls for a different finish from a ceiling in an agricultural building. We can help choose tapes and accessories, and compare offers for complete, compatible systems.

Send a section drawing of the roof, floor or wall you want to insulate. We can identify suitable boards and check current stock. Selecting PIR to suit the available space can help make the refurbished building more comfortable to live or work in.
