Celotex PIR Insulation Delivered to Wrexham and North Wales
We deliver Celotex PIR insulation boards (now being rebranded as Sopratherm) to Wrexham and across north Wales, from Flintshire and Deeside along the coast to Rhyl, Llandudno and Bangor. North Wales jobs include older stone cottages, bungalows, barn and outbuilding conversions and new extensions, and many are on rural sites, so this guide covers access as well as the right boards.

Typical north Wales projects and which Celotex boards to use
Stone cottages and solid walls
Older cottages across north Wales often have thick solid stone walls. Insulated plasterboard can improve them from the inside, but solid stone needs care with moisture, so get advice on the right build-up first:
- Celotex PL4000 Insulated Plasterboard 2400 × 1200mm – 37.5mm (25mm + 12.5mm, now Sopratherm PL4025, 2.88m² sheet) – £40.21 a sheet ex VAT
- Celotex PL4000 Insulated Plasterboard 2400 × 1200mm – 52.5mm (40mm + 12.5mm, now Sopratherm PL4040, 2.88m² sheet) – £50.07 a sheet ex VAT
Bungalows, lofts and roofs
For insulating a pitched roof at rafter level, or a room-in-roof, GA4000 boards are a common choice. The full-size boards are 2400 × 1200mm (2.88m²) with a declared thermal conductivity of 0.022 W/mK:
- Celotex GA4000 PIR Insulation Board 2400 × 1200mm – 75mm (now Sopratherm GA4075, 2.88m² sheet) – £28.24 a sheet ex VAT
- Celotex GA4000 PIR Insulation Board 2400 × 1200mm – 80mm (now Sopratherm GA4080, 2.88m² sheet) – £32.35 a sheet ex VAT
- Celotex GA4000 PIR Insulation Board 2400 × 1200mm – 100mm (now Sopratherm GA4100, 2.88m² sheet) – £34.30 a sheet ex VAT
Barn and outbuilding conversions, extensions and floors
Conversions and extensions usually need thicker boards for floors and roofs:
- Celotex XR4000 PIR Insulation Board 2400 × 1200mm – 120mm (now Sopratherm XR4120, 2.88m² sheet) – £44.17 a sheet ex VAT
- Celotex XR4000 PIR Insulation Board 2400 × 1200mm – 150mm (now Sopratherm XR4150, 2.88m² sheet) – £51.66 a sheet ex VAT
See our warm flat roof PIR guide and use the PIR U-value calculator to compare build-ups.
Prices are the live website prices at the time of writing (10 November 2026), per sheet, ex VAT. Prices can change, so check the product page for the current price. Celotex boards are being rebranded as Sopratherm, so you will see both names on our product pages.
Getting your north Wales delivery right
- Tell us about rural access. Single-track lanes, steep drives, farm tracks, weight limits or low bridges all affect delivery. Let us know when you order so we can plan it.
- Order the whole job at once. Delivery is £40 + VAT per order, so one larger order keeps the cost down.
- Store boards flat and dry, off the ground and covered.
Frequently asked questions
What does delivery to Wrexham cost?
£40 + VAT (£48 inc VAT) on every Celotex order to mainland Wales, with a £400 ex VAT minimum. There is no free-delivery threshold for Wales orders.
I have a CH postcode. Which delivery rules apply?
CH postcodes cover both Flintshire in Wales and Chester and the Wirral in England. Welsh addresses follow the Wales rules above.

Can I get next-day delivery?
No. We confirm the delivery date when your order is placed and do not offer next-day delivery.

Mainland addresses in Eryri are in our Wales delivery area. Rural access can be tricky, so tell us about the site when you order.
