Picking the right product

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.

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.

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.

• Clear a level area for pallets, ideally on boards, so materials stay out of standing water.
• For a phased build we can split the order so materials arrive as each stage starts, which keeps the site clear.
• Weight limits on bridges or private roads near the site matter for larger lorries, so mention any you know of.

Ordering PIR insulation boards for Letchworth Garden City: FAQs

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.

Is PIR better than mineral wool?

PIR insulates more per millimetre, so it suits tight spaces. Mineral wool is non-combustible, cheaper per square metre and better for sound.

Can you deliver PIR insulation boards to a site with restricted access in Letchworth Garden City?

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.

How soon can PIR insulation boards be delivered in Letchworth Garden City?

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.
