Delivery to Farnham: what helps

Boards are light but bulky; they travel in wrapped packs and should be stored flat and dry. Farnham is inside our standard mainland delivery area.

• Deliveries are to the kerb, drive or within crane reach; ask if materials need to go further.
• Weight limits on bridges or private roads near the site matter for larger lorries, so mention any you know of.
• Give us the full postcode for the drop point; deliveries around GU9 are priced to the exact address.

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 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 Farnham

Can I add other materials to my Farnham 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.

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.
