Before your Leyland delivery arrives

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

• Give us the full postcode for the drop point; deliveries around PR25 are priced to the exact address.
• Pallets left on a pavement can block the footway, so plan a drop point inside your boundary where you can.
• For a phased build we can split the order so materials arrive as each stage starts, which keeps the site clear.

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.

Common questions from Leyland

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 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.

How soon can PIR insulation boards be delivered in Leyland?

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 there a minimum order for delivery to Leyland?
