Getting PIR insulation boards onto your Gwynedd site

Boards are light but bulky; they travel in wrapped packs and should be stored flat and dry. Our standard mainland delivery area covers Gwynedd.

• If the site is up a shared drive or behind other houses, tell us the distance from the road.
• On busy streets in Gwynedd, a parking suspension or a quiet time slot can make offloading safer, so tell us about local restrictions you know of.
• Clear a level area for pallets, ideally on boards, so materials stay out of standing water.

Before you order PIR insulation boards

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.

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.

Your questions answered

Is PIR better than mineral wool?

PIR insulates more per millimetre, so it suits tight spaces. Mineral wool is non-combustible, cheaper per square metre and better for sound.

How soon can PIR insulation boards be delivered in Gwynedd?

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 I add other materials to my Gwynedd 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.
