Getting the right PIR insulation boards

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.

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.

How delivery works in Bristol

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

• Deliveries are to the kerb, drive or within crane reach; ask if materials need to go further.
• Keep cement, plaster and boards dry: have a tarpaulin or a garage space ready before they arrive.
• If the site is up a shared drive or behind other houses, tell us the distance from the road.

How much will you need?

Insulating 12 m² of rafters, floor or wall takes 5 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

Common questions from Bristol

How soon can PIR insulation boards be delivered in Bristol?

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 you deliver PIR insulation boards to a site with restricted access in Bristol?

Usually, yes. Tell us about the access when you ask for a price and we will plan the vehicle and offload, or say if a smaller vehicle is needed.

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.
