Sizing your order

Insulating 36 m² of rafters, floor or wall takes 14 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 Hertfordshire delivery arrives

Boards are light but bulky; they travel in wrapped packs and should be stored flat and dry. Our standard mainland delivery area covers Hertfordshire.

• Pallets left on a pavement can block the footway, so plan a drop point inside your boundary where you can.
• On busy streets in Hertfordshire, a parking suspension or a quiet time slot can make offloading safer, so tell us about local restrictions you know of.
• Mention any overhead cables, low branches or narrow gateways, because they decide whether a crane offload is possible.

Choosing 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.

Questions about PIR insulation boards delivery in Hertfordshire

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.

Can I add other materials to my Hertfordshire 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.

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

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

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.
