Getting PIR insulation boards onto your Litherland site

• 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 L21 are priced to the exact address.
• If the drop point is block paving or soft ground, say so; heavy pallets and bulk bags can mark or sink.

Choosing 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.

PIR Insulation Boards in Litherland: questions

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.

Is there a minimum order for delivery to Litherland?

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 Litherland?

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.
