Estimating your PIR insulation boards

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

Picking the right product

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.

Delivering PIR insulation boards in Blackheath

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

• If neighbours share the access, it helps to let them know a lorry is coming.
• If the site is up a shared drive or behind other houses, tell us the distance from the road.
• Clear a level area for pallets, ideally on boards, so materials stay out of standing water.

Your questions answered

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

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

Is there a minimum order for delivery to Blackheath?

There is no fixed minimum. For very small orders we will tell you honestly if the delivery cost outweighs the materials, so you can decide.

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.

What is the foil for?

The foil facing reflects heat, protects the foam and, when joints are taped, can act as a vapour control layer.
