Why buy PIR boards from a PIR specialist?

Builders’ merchants stock hundreds of products and treat insulation as one line among many. We do the opposite. General purpose PIR insulation boards are the only thing we sell, so we hold one specification across every manufacturer we work with and send whichever brand is best stocked for your postcode. Fewer products means better buying, fewer back-orders and a lead time we can actually promise: order before 2:30pm on a working day and your boards arrive in 3 working days on average.

Every board is 2400mm x 1200mm and covers 2.88m². Thermal conductivity is 0.022 W/mK across the range, so the U-value you calculate is the U-value you get, whichever name is on the foil. Use the order form to add several thicknesses at once, see your total coverage as you go, and get free delivery on orders over £450 + VAT.

Questions, answered

Which brand will I receive?

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.

Are the boards new?

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.

Are the boards really the same specification?

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.

How quickly will my order arrive?

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.

How much does delivery cost?

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.

How many boards do I need?

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.

Can I mix thicknesses in one order?

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

Add every thickness you need in one go. Free delivery over £450 + VAT.
