Choosing PIR insulation boards

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.

How delivery works in East Grinstead

Boards are light but bulky; they travel in wrapped packs and should be stored flat and dry. East Grinstead 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.
• With roughly 7h 53m of daylight in East Grinstead around the shortest day, morning deliveries leave more working light for the job.
• For a phased build we can split the order so materials arrive as each stage starts, which keeps the site clear.

Common questions from East Grinstead

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.

How many PIR boards do I need?

Divide the area by 2.88 m² (one 2400 × 1200 board) and add about 5 to 10 percent for cutting.

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

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.

Can I add other materials to my East Grinstead delivery?

Yes. Put everything on one list, from PIR insulation boards to fixings and PPE, and we will price it as one delivery where the products can travel together.
