Things to check before you order

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.

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.

Getting PIR insulation boards onto your Longton site

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

• Weight limits on bridges or private roads near the site matter for larger lorries, so mention any you know of.
• Pallets left on a pavement can block the footway, so plan a drop point inside your boundary where you can.
• Give us the full postcode for the drop point; deliveries around ST3 are priced to the exact address.

Quantities: a worked example

Insulating 30 m² of rafters, floor or wall takes 12 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

Ordering PIR insulation boards for Longton: FAQs

Is there a minimum order for delivery to Longton?

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 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.

Do you deliver PIR insulation boards to trades and homeowners in Longton?

Both. Trades can apply for a trade account; homeowners and self-builders can order on a delivered quote.

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.
