- On busy streets in Falmouth, a parking suspension or a quiet time slot can make offloading safer, so tell us about local restrictions you know of.
- Mention any overhead cables, low branches or narrow gateways, because they decide whether a crane offload is possible.
- Weight limits on bridges or private roads near the site matter for larger lorries, so mention any you know of.
Working out quantities for your Falmouth job
Insulating 16 m² of rafters, floor or wall takes 6 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 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 England, building work is checked against the Approved Documents, for example Part A for structure and Part L for energy efficiency, through your council's building control team or a registered building control approver.
Common questions from Falmouth
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.
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.
Can I add other materials to my Falmouth 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 soon can PIR insulation boards be delivered in Falmouth?
We confirm the delivery date when we price your order, before you commit. It depends on the product, the quantity and whether it is a stock line or made to order.
