PIR Insulation Boards: choosing well

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.

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.

Sizing your order

Insulating 16 m² of rafters, floor or wall takes 6 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 Greenwich delivery arrives

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

• Have someone on site for the delivery if you can, or agree a safe drop point with us in advance.
• 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.

Questions about PIR insulation boards delivery in Greenwich

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

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.

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 Greenwich?

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

How thick should PIR insulation be?

It depends on where it goes and the U-value required. Pitched roofs often need 100 mm or more between and under rafters; floors and walls vary. Use the maker's U-value tables or ask your designer.
