Delivery to Winchester: what helps

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

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

Choosing PIR insulation boards

Fire considerations

PIR is a combustible product. Building regulations restrict combustible materials in some situations, such as external walls of taller buildings; check what applies.

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.

PIR Insulation Boards in Winchester: questions

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.

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.

How soon can PIR insulation boards be delivered in Winchester?
