Delivery to Ayrshire: what helps
Boards are light but bulky; they travel in wrapped packs and should be stored flat and dry. Our standard mainland delivery area covers Ayrshire.
- If the drop point is block paving or soft ground, say so; heavy pallets and bulk bags can mark or sink.
- Weight limits on bridges or private roads near the site matter for larger lorries, so mention any you know of.
- Have someone on site for the delivery if you can, or agree a safe drop point with us in advance.
PIR Insulation Boards: choosing well
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.
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.
In Scotland most building work needs a building warrant from the local authority, assessed against the Building Standards Technical Handbooks.
Ordering PIR insulation boards for Ayrshire: FAQs
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 I add other materials to my Ayrshire 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 Ayrshire?
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.
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.
