Before you order PIR insulation boards

Fire considerations

PIR is a combustible product. Building regulations restrict combustible materials in some situations, such as external walls of taller buildings; check what applies.

Thickness for the U-value

The thickness you need depends on the U-value the building regulations require and the rest of the build-up. Manufacturers publish U-value tables; your designer or building control will confirm.

In England, building work is checked against the Approved Documents, for example Part A for structure and Part L for energy efficiency, through your council's building control team or a registered building control approver.

The foil facing reflects heat, protects the foam and, when joints are taped, can act as a vapour control layer.

In some situations, but building regulations restrict combustible insulation in external walls of certain buildings. Check the rules for your building.
