Before you order 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.

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.

Getting PIR insulation boards onto your Newtown site

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

• If neighbours share the access, it helps to let them know a lorry is coming.
• If the site is up a shared drive or behind other houses, tell us the distance from the road.
• With roughly 7h 39m of daylight in Newtown around the shortest day, morning deliveries leave more working light for the job.

Your questions answered

How soon can PIR insulation boards be delivered in Newtown?

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.

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.

Can I add other materials to my Newtown delivery?

Yes. Put everything on one list, from PIR insulation boards to fixings and PPE, and we will price it as one delivery where the products can travel together.

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.
