What does a laminate facing change in a PIR panel?

Before ordering, ask for a cross-section and details of both faces. The outer face may be steel or, on an insulation board, a flexible multilayer facing. The laminate determines the appearance of the inner surface. The description “glass fibre board” is too broad for designing an enclosure.

A laminate-faced insulation board can line a soffit when fitted in its intended system. A rigid core alone gives no basis for using it to span a roof. Provide the required supports, fixings and protection for the other faces.

A roof panel with profiled steel outside and laminate inside is a different product. Use structural data for that configuration. Replacing the lower steel facing with laminate can change strength and fixing requirements. Check applicability before using another panel’s tables.

Laminate is often considered in livestock buildings and rooms cleaned regularly. Suitability depends on resistance to the actual substances, temperatures and cleaning method. Describe the chemicals used as well as contact with condensate and dirt in the enquiry.

General chemical resistance does not cover every agent at any concentration. Brief washing with a diluted product differs from leaving residues for a long period. Check compatibility with the maintenance procedure, contact time and rinsing instructions.

Water and cleaning agents reach joints, fasteners and panel ends as well as the smooth face. Exposed core and poorly finished profiles can trap dirt. Detail the closure of every cut edge and service penetration.

Select sealants and profiles for the environment and facing. Allow for expected movement and future inspection. Pressure-washing limits must cover joints too. The laminate’s resistance does not establish that a jet can be aimed into a joint at any angle.

Core compressive strength does not determine the capacity of a complete roof. For soffits, check deflection, support spacing and fixings into the structure. Roof panels need applicable load tables and joint data. Match every figure to the offered thickness and facing combination.

Reaction to fire of the product and fire resistance of the assembly are distinct properties. A classification for two steel faces cannot be transferred to a different facing. Obtain documentation for the actual assembly and establish building-specific requirements before selection.

Use a sample to judge texture, colour and how readily scratches show. Examine a finished edge and its profile joint. For a specified cleaner, obtain compatibility confirmation and a procedure for testing an inconspicuous spot. A new sample alone cannot predict performance in use.

Specify the function, environment, product type and accessories in the order. On receipt inspect the laminate and edges for damage or delamination. Keep the cleaning and repair instructions so staff can maintain the surface without compromising joints or core protection.
