PIR Insulation Boards: choosing well

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 Northern Ireland building work follows the Building Regulations (Northern Ireland), with guidance in the Technical Booklets, and applications go to the council's building control team.

Quantities: a worked example

Insulating 20 m² of rafters, floor or wall takes 8 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

Planning the drop in Derry/Londonderry

Boards are light but bulky; they travel in wrapped packs and should be stored flat and dry. Deliveries to Northern Ireland include a sea crossing, so we quote each order individually.

• Mention any overhead cables, low branches or narrow gateways, because they decide whether a crane offload is possible.
• Have someone on site for the delivery if you can, or agree a safe drop point with us in advance.
• If neighbours share the access, it helps to let them know a lorry is coming.

PIR Insulation Boards questions

Do you deliver PIR insulation boards to Derry/Londonderry?

Yes. We deliver across Derry/Londonderry, including BT47, BT48. Deliveries to Northern Ireland include a sea crossing, so we quote each order individually. Send your list or call 0800 088 6341 and we will price it delivered to your postcode.

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.

Is PIR better than mineral wool?

PIR insulates more per millimetre, so it suits tight spaces. Mineral wool is non-combustible, cheaper per square metre and better for sound.

Can you deliver PIR insulation boards to a site with restricted access in Derry/Londonderry?

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.
