Insulating an agricultural building requires establishing where the boundary of the heated or controlled zone should run. For a warehouse, workshop and livestock area, the arrangement of walls, ceiling and openings will differ. On Izoprofil.pl we discuss the preparation of details that connect these surfaces: the edges of the ceiling lining, partition walls, doors and service penetrations. The plan should specify the support, sealing, protection of exposed edges and access to equipment. A PIR insulation board and an insulated sandwich panel with steel facings perform different functions; substituting one for the other requires the whole solution to be checked. Documentation of the material, assessment of the existing structure and moisture conditions precede ordering. A refurbishment prepared in this way can be priced and accepted according to specific connections, not solely by the area of insulation.

The aluminium facing on a PIR board affects the passage of water vapour through the insulation layer. However, it does not in itself seal joints, corners or service penetrations. With internal insulation, the continuity of the entire system is what matters. Equally important are the condition of the existing masonry and its ability to dry out after the build-up has been installed. The metallic surface may be a multi-layer facing incorporating aluminium, paper and plastic. It should not be treated like any kitchen foil, nor should identical properties be assumed for every shiny product. The declared parameters of the specific product and the solution intended for the wall are what count.
