Picking the right product

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.

A quick quantity check

Insulating 30 m² of rafters, floor or wall takes 12 boards of 2400 × 1200 mm including offcuts. The thickness depends on the U-value you need, so check it before you order. Try the insulation calculator

• Have someone on site for the delivery if you can, or agree a safe drop point with us in advance.
• In summer Sevenoaks gets around 16h 36m of daylight, but early deliveries still beat the traffic and give the longest working day.
• On busy streets in Sevenoaks, a parking suspension or a quiet time slot can make offloading safer, so tell us about local restrictions you know of.
