Things to check before you order

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.

In England, building work is checked against the Approved Documents, for example Part A for structure and Part L for energy efficiency, through your council's building control team or a registered building control approver.

Quantities: a worked example

Insulating 24 m² of rafters, floor or wall takes 9 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

Getting PIR insulation boards onto your Nailsea site

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

• Give us the full postcode for the drop point; deliveries around BS48 are priced to the exact address.
• In summer Nailsea gets around 16h 38m of daylight, but early deliveries still beat the traffic and give the longest working day.
• Deliveries are to the kerb, drive or within crane reach; ask if materials need to go further.

Questions about PIR insulation boards delivery in Nailsea

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

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

Can I add other materials to my Nailsea 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.

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 many PIR boards do I need?

Divide the area by 2.88 m² (one 2400 × 1200 board) and add about 5 to 10 percent for cutting.
