Before your Cumbria delivery arrives
Boards are light but bulky; they travel in wrapped packs and should be stored flat and dry. Our standard mainland delivery area covers Cumbria.
- Give us the full postcode for the drop point; deliveries around CA are priced to the exact address.
- If the site is up a shared drive or behind other houses, tell us the distance from the road.
- Mention any overhead cables, low branches or narrow gateways, because they decide whether a crane offload is possible.
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.
PIR Insulation Boards in Cumbria: questions
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 there a minimum order for delivery to Cumbria?
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.
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.
How soon can PIR insulation boards be delivered in Cumbria?
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.
