• Pallets left on a pavement can block the footway, so plan a drop point inside your boundary where you can.
• If the site is up a shared drive or behind other houses, tell us the distance from the road.
• For a phased build we can split the order so materials arrive as each stage starts, which keeps the site clear.

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.

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.

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 South Glamorgan

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 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.

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

Both. Trades can apply for a trade account; homeowners and self-builders can order on a delivered quote.

How soon can PIR insulation boards be delivered in South Glamorgan?
