Things to check before you order

Sealing joints

Tape the joints with foil tape so the foil layer works as a continuous vapour control layer where the design relies on it.

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.

Planning the drop in Kendal

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

• Give us the full postcode for the drop point; deliveries around LA9 are priced to the exact address.
• On busy streets in Kendal, a parking suspension or a quiet time slot can make offloading safer, so tell us about local restrictions you know of.
• If the site is up a shared drive or behind other houses, tell us the distance from the road.

Common questions from Kendal

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.

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.

Can I add other materials to my Kendal delivery?

Yes. Put everything on one list, from PIR insulation boards to fixings and PPE, and we will price it as one delivery where the products can travel together.

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

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