PIR Insulation Boards: choosing well

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.

Quantities: a worked example

Insulating 24 m² of rafters, floor or wall takes 9 boards of 2400 × 1200 mm including offcuts. The thickness depends on the U-value you need, so check it before you order. Try the insulation calculator

Ordering PIR insulation boards for Hemel Hempstead: FAQs

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

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

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.

How soon can PIR insulation boards be delivered in Hemel Hempstead?

We confirm the delivery date when we price your order, before you commit. It depends on the product, the quantity and whether it is a stock line or made to order.

Is PIR better than mineral wool?

PIR insulates more per millimetre, so it suits tight spaces. Mineral wool is non-combustible, cheaper per square metre and better for sound.
