Getting the right 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.

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.

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.

Delivery to Widnes: what helps

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

• Have someone on site for the delivery if you can, or agree a safe drop point with us in advance.
• Weight limits on bridges or private roads near the site matter for larger lorries, so mention any you know of.
• With roughly 7h 30m of daylight in Widnes around the shortest day, morning deliveries leave more working light for the job.

Your questions answered

Can PIR be used in external walls?

In some situations, but building regulations restrict combustible insulation in external walls of certain buildings. Check the rules for your building.

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.

Can I add other materials to my Widnes 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.

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

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.
