Planning the drop in Belfast

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.

• For a phased build we can split the order so materials arrive as each stage starts, which keeps the site clear.
• Keep cement, plaster and boards dry: have a tarpaulin or a garage space ready before they arrive.
• If the drop point is block paving or soft ground, say so; heavy pallets and bulk bags can mark or sink.

How much will you need?

Insulating 30 m² of rafters, floor or wall takes 12 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

Choosing PIR insulation boards

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.

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 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.

Ordering PIR insulation boards for Belfast: FAQs

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.

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.

Do you deliver PIR insulation boards to trades and homeowners in Belfast?
