• Weight limits on bridges or private roads near the site matter for larger lorries, so mention any you know of.

Before you order PIR insulation boards

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.

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.

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.

Questions about PIR insulation boards delivery in Trowbridge

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.

Is there a minimum order for delivery to Trowbridge?

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.

Can you deliver PIR insulation boards to a site with restricted access in Trowbridge?

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.

Can PIR be used in external walls?

In some situations, but building regulations restrict combustible insulation in external walls of certain buildings. Check the rules for your building.
