Things to check before you order

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.

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.

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.

Common questions from Ewell

How thick should PIR insulation be?

It depends on where it goes and the U-value required. Pitched roofs often need 100 mm or more between and under rafters; floors and walls vary. Use the maker's U-value tables or ask your designer.

Do you deliver PIR insulation boards to trades and homeowners in Ewell?

Both. Trades can apply for a trade account; homeowners and self-builders can order on a delivered quote.

Is there a minimum order for delivery to Ewell?

There is no fixed minimum. For very small orders we will tell you honestly if the delivery cost outweighs the materials, so you can decide.

What is the foil for?

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