Polyurethane roof sandwich panel 40 mm, outlet grade 2 — product specification

Where an envelope must insulate well while leaving flexibility in design, PIR sandwich panels offer a practical option. Rigid foam works together with metal facings. The result is a ready-made enclosure element combining thermal protection with surfaces intended for everyday use.

The low thermal conductivity of PIR foam can provide the required insulation with a relatively thin core. This matters when extending a room within an existing structure, around narrow reveals and at the wall-to-roof junction. A slimmer envelope leaves more room for use or connection details. The foam’s closed-cell structure helps maintain its properties. Thickness is selected for the intended room use so the insulation supports heating or cooling. This makes it easier to create zones at different temperatures within one building while retaining a compact arrangement.

An installed panel immediately provides both outer and inner surfaces. In a service pavilion or production hall, fewer separate surfaces need lining and finishing. The core is bonded to the sheet metal across the panel, so the installer handles one composite component. With suitable support spacing, this construction can form even envelope areas. Coatings selected for the operating environment help preserve the facings’ appearance and allow cleaning in accordance with the manufacturer’s instructions.

PIR wall panels are available in versions that allow horizontal or vertical layouts. This helps align façades with doors and glazing and achieve the intended joint pattern. Surface profiling provides a subtle texture, while the fixing system affects whether fasteners remain visible. Roof panels have geometry intended for roof use. Walls and roofs can therefore share the concept of an insulated envelope while retaining the appropriate solution for each application. Facing colours may distinguish customer areas while the rest of the building remains visually restrained. These decorative areas do not require a separate added insulation layer simply to create the colour distinction.

PIR is used in warehouses, workshops, retail service spaces and agricultural buildings. It is particularly useful for creating a heated area within a larger hall: surfaces are completed efficiently and insulation forms part of the envelope from the start. The core’s low weight supports lightweight enclosure solutions. Carefully detailed joints and flashings complete thermal protection at corners and openings. Fire properties must be taken from the documentation of the selected panel; PIR itself is not non-combustible.

SteelProfil offers PIR wall and roof panels at competitive prices. The range includes stock availability, first and second grades, and promotions on building materials. Compare the available options and choose the appropriate panel for an efficiently constructed, insulated building envelope.
