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.

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.

How delivery works in Holywood

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.

• If the site is up a shared drive or behind other houses, tell us the distance from the road.
• If the drop point is block paving or soft ground, say so; heavy pallets and bulk bags can mark or sink.
• On busy streets in Holywood, a parking suspension or a quiet time slot can make offloading safer, so tell us about local restrictions you know of.

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.

Can I add other materials to my Holywood 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.

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 Holywood?

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.
