PIR Insulation Boards: choosing well

Sealing joints

Tape the joints with foil tape so the foil layer works as a continuous vapour control layer where the design relies on it.

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.

Getting PIR insulation boards onto your Hanworth site

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

• Keep cement, plaster and boards dry: have a tarpaulin or a garage space ready before they arrive.
• For a phased build we can split the order so materials arrive as each stage starts, which keeps the site clear.
• In summer Hanworth gets around 16h 38m of daylight, but early deliveries still beat the traffic and give the longest working day.

Estimating your PIR insulation boards
