Before you order 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.

Estimating your PIR insulation boards

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 Bishop's Stortford delivery arrives

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

• Mention any overhead cables, low branches or narrow gateways, because they decide whether a crane offload is possible.
• Clear a level area for pallets, ideally on boards, so materials stay out of standing water.
• With roughly 7h 46m of daylight in Bishop's Stortford around the shortest day, morning deliveries leave more working light for the job.

Common questions from Bishop's Stortford

Is there a minimum order for delivery to Bishop's Stortford?

There is no fixed minimum. For very small orders we will tell you honestly if the delivery cost outweighs the materials, so you can decide.

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 Bishop's Stortford?

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.
