termPIR AL SIP panel, 20 mm PIR core + 1 × 8 mm OSB

SIP panels with a PIR core and OSB facing combine thermal insulation with a board surface for subsequent building work. They are an option for contractors working on framed structures, modular buildings and refurbished assemblies. Instead of fitting successive layers separately, you receive a factory-bonded component. This helps organise installation and reduce the number of individual operations on site.

The rigid PIR foam core provides effective insulation within a slim build-up. OSB gives the composite a stiffer outer surface and can support further layers specified in the design. Versions with OSB on one side and on both sides are available. Selecting the core and sheathing thicknesses allows the material to be matched to the proposed assembly, supports and finishing requirements.

Prefabrication helps maintain consistent components and organise the work. Large boards can be cut to the required geometry, while a carefully prepared cutting plan reduces waste. Fewer separate layers to move and fit can simplify logistics, especially on small projects or restricted sites. The greatest benefit comes when panel dimensions and the structural layout are planned together.

PIR and OSB panels are used within insulation and sheathing solutions for framed construction, including walls, roofs or floors where the product documentation permits that application. They can be useful in modular buildings, leisure properties and alterations to existing assemblies. Selection depends on the insulation required, the support arrangement and protection of the surface from external conditions.

Not every panel sold as SIP is an independently load-bearing component. Structural function, permissible loads and support spacing must be established for the particular product and design. Joint sealing, protection of OSB from moisture and the selection of subsequent layers are equally important. SteelProfil helps identify the required version so that a composite board can be used within an appropriately designed building assembly.

Before ordering, establish openings, the intended finish and service routes. This helps coordinate panel divisions and the installation sequence. A well-prepared component schedule assists the contractor and makes better use of prefabrication.

We supply SIP panels selected for individual orders alongside a wide range of complementary materials. SteelProfil’s wider range includes first- and second-grade products and many stocked items. The production lead time for a particular SIP panel is confirmed with the quotation according to its construction and the quantity required. Competitive prices and promotions can help manage the cost of the complete assembly. Send the dimensions and project requirements so we can prepare a suitable package with the necessary accessories.
