PIR Insulation Boards: choosing well
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.
Sizing your order
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
Before your Neath delivery arrives
Boards are light but bulky; they travel in wrapped packs and should be stored flat and dry. Neath is inside our standard mainland delivery area.
- If the site is up a shared drive or behind other houses, tell us the distance from the road.
- Weight limits on bridges or private roads near the site matter for larger lorries, so mention any you know of.
- With roughly 7h 48m of daylight in Neath around the shortest day, morning deliveries leave more working light for the job.
PIR Insulation Boards questions
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 Neath 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 soon can PIR insulation boards be delivered in Neath?
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.
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.
