Getting PIR insulation boards onto your Eltham site

Boards are light but bulky; they travel in wrapped packs and should be stored flat and dry. Eltham is inside our standard mainland delivery area.

• Mention any overhead cables, low branches or narrow gateways, because they decide whether a crane offload is possible.
• Have someone on site for the delivery if you can, or agree a safe drop point with us in advance.
• On busy streets in Eltham, a parking suspension or a quiet time slot can make offloading safer, so tell us about local restrictions you know of.

Getting the right 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.

Common questions from Eltham

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

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

Can PIR be used in external walls?

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

Can you deliver PIR insulation boards to a site with restricted access in Eltham?

Usually, yes. Tell us about the access when you ask for a price and we will plan the vehicle and offload, or say if a smaller vehicle is needed.

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.
