Getting the right PIR insulation boards

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.

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.

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.

Estimating your PIR insulation boards

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

Planning the drop in Norwich

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

• Mention any overhead cables, low branches or narrow gateways, because they decide whether a crane offload is possible.
• If neighbours share the access, it helps to let them know a lorry is coming.
• Weight limits on bridges or private roads near the site matter for larger lorries, so mention any you know of.

Ordering PIR insulation boards for Norwich: FAQs

Is there a minimum order for delivery to Norwich?

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.

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.

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

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