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.

Planning the drop in Chichester

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

• If the drop point is block paving or soft ground, say so; heavy pallets and bulk bags can mark or sink.
• In summer Chichester gets around 16h 31m 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.

Common questions from Chichester

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

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

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.

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.

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

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.
