Before your Catford delivery arrives

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

• If neighbours share the access, it helps to let them know a lorry is coming.
• Have someone on site for the delivery if you can, or agree a safe drop point with us in advance.
• If the drop point is block paving or soft ground, say so; heavy pallets and bulk bags can mark or sink.

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.

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.

Working out quantities for your Catford job

Insulating 20 m² of rafters, floor or wall takes 8 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

PIR Insulation Boards questions

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.

How soon can PIR insulation boards be delivered in Catford?

We confirm the delivery date when we price your order, before you commit. It depends on the product, the quantity and whether it is a stock line or made to order.

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.
