Delivering PIR insulation boards in Dunoon

Boards are light but bulky; they travel in wrapped packs and should be stored flat and dry. Dunoon is in an area where deliveries are priced individually because of the distance and access, so we quote each order separately.

• With roughly 6h 57m of daylight in Dunoon around the shortest day, morning deliveries leave more working light for the job.
• If neighbours share the access, it helps to let them know a lorry is coming.
• In summer Dunoon gets around 17h 36m of daylight, but early deliveries still beat the traffic and give the longest working day.

Sizing your order

Insulating 24 m² of rafters, floor or wall takes 9 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

Before you order 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 the council's building standards service 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 Scotland most building work needs a building warrant from the local authority, assessed against the Building Standards Technical Handbooks.

PIR Insulation Boards questions

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.

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 Dunoon?

Both. Trades can apply for a trade account; homeowners and self-builders can order on a delivered quote.

Is there a minimum order for delivery to Dunoon?

There is no fixed minimum. For very small orders we will tell you honestly if the delivery cost outweighs the materials, so you can decide.
