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.

Wales has its own Approved Documents, including its own Part L for energy efficiency, and building control is handled by the local authority or a registered approver.

How delivery works in Caernarfon

• With roughly 7h 32m of daylight in Caernarfon around the shortest day, morning deliveries leave more working light for the job.

• Tell us the best drop point, such as a driveway, front garden or the kerb, and whether a lorry can park close to it.

Your questions answered

Is there a minimum order for delivery to Caernarfon?

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.

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.

How soon can PIR insulation boards be delivered in Caernarfon?

We confirm the delivery date when we price your order, before you commit. It depends on the product, the quantity and whether it is a stock line or made to order.
