Choosing 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.

Planning the drop in Bentley

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

• In summer Bentley gets around 17h 03m of daylight, but early deliveries still beat the traffic and give the longest working day.
• With roughly 7h 28m of daylight in Bentley around the shortest day, morning deliveries leave more working light for the job.
• Keep cement, plaster and boards dry: have a tarpaulin or a garage space ready before they arrive.

PIR Insulation Boards 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.

Can you deliver PIR insulation boards to a site with restricted access in Bentley?

Usually, yes. Tell us about the access when you ask for a price and we will plan the vehicle and offload, or say if a smaller vehicle is needed.

What is the foil for?

The foil facing reflects heat, protects the foam and, when joints are taped, can act as a vapour control layer.
