One of the brands shown on our site, currently Kingspan, Celotex, Soprema, Unilin, IKO, Ecotherm, Mannok or Recticel. We only sell general purpose PIR boards and every manufacturer we work with makes theirs to the same specification: 2400 x 1200, foil faced both sides, 0.022 W/mK. We send whichever brand is best stocked for your postcode, which is how we offer lower prices and faster delivery. You cannot choose a specific brand.

Yes. Every board we sell is brand new, factory fresh stock from the manufacturer, never seconds, surplus or reclaimed. It arrives in the manufacturer's packaging on a pallet.

Yes. Thermal conductivity, thickness, board size and facings are identical across the brands we supply, so the U-value you achieve is the same whichever one arrives. The only difference is the name printed on the foil.

Order before 2:30pm on a working day and the earliest delivery is 3 working days, on average. Orders after 2:30pm, or at the weekend, take 4 working days on average. Dates can vary by area and availability, and we confirm your date by email once the order is booked. At checkout you can choose ASAP or request a later date.

Delivery is free on orders over £450.00 + VAT to most of the UK mainland. Smaller orders pay a flat delivery charge that is shown at checkout once you enter your postcode. A few postcode areas have their own rates, and we cannot deliver to Northern Ireland, the islands or the far north of Scotland. Full details are on the delivery page.

Each board covers 2.88m². Divide your area by 2.88 and round up, allowing a little extra for cuts. The order form calculator does this for you.

Yes. Use the order form to add several thicknesses at once, or add boards from the individual product pages. Everything ships together.

General purpose PIR boards are used in floors (under screed, between joists, over beam and block), walls (timber frame, internal linings) and roofs (between or over rafters, warm flat roofs). The thickness you need depends on the target U-value and the build-up; the specification tab gives the R-value for this thickness.

For a warm roof or where the foil is acting as a vapour control layer, yes: tape the joints with a foil tape. For floors under screed, lap the joints tightly and use a polythene separating layer over the boards.

Boards arrive on a large curtain-sided lorry, delivered kerbside. Someone must be on site to accept the delivery, check the boards and help offload. If access is tight for an HGV, reply to your order confirmation on the day you order so we can plan the delivery.

Yes. At checkout choose "Request a delivery date" and pick a working day from the earliest available date. We confirm the date by email when the order is booked.

Check the boards before you sign. Note any damage on the delivery paperwork and email us with your order number while the driver is on site, so we can sort a replacement.
