Delivery to East Sussex: what helps
Boards are light but bulky; they travel in wrapped packs and should be stored flat and dry. Our standard mainland delivery area covers East Sussex.
- If the site is up a shared drive or behind other houses, tell us the distance from the road.
- Tell us the best drop point, such as a driveway, front garden or the kerb, and whether a lorry can park close to it.
- If neighbours share the access, it helps to let them know a lorry is coming.
Getting the right PIR insulation boards
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.
PIR Insulation Boards in East Sussex: questions
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 East Sussex 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.
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 East Sussex?
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.
