Delivery to Penarth: what helps

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

• Deliveries are to the kerb, drive or within crane reach; ask if materials need to go further.
• Have someone on site for the delivery if you can, or agree a safe drop point with us in advance.
• If the site is up a shared drive or behind other houses, tell us the distance from the road.

Choosing 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.

Common questions from Penarth

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.

Can I add other materials to my Penarth 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.

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

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.
