Getting PIR insulation boards onto your Leatherhead site

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

• Weight limits on bridges or private roads near the site matter for larger lorries, so mention any you know of.
• In summer Leatherhead gets around 16h 36m of daylight, but early deliveries still beat the traffic and give the longest working day.
• Have someone on site for the delivery if you can, or agree a safe drop point with us in advance.

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.
