Insulation Delivery Norwich: Celotex, PIR and Plasterboard Delivered Across Norfolk

Norfolk is a county of contrasts: Victorian terraces and 1930s semis across Norwich, flint-faced cottages in the villages, converted barns in the countryside, and steady new-build growth around Wymondham, Dereham and the edges of the city. We deliver insulation, plasterboard, drylining and suspended ceiling materials direct to sites and homes across Norwich and Norfolk, with Celotex PIR boards at some of our sharpest trade prices. This guide covers what Norfolk projects usually need, how our delivery terms work and how to plan delivery to a rural or city site.

Celotex and PIR insulation in Norwich and Norfolk

PIR boards are the workhorse for floors, pitched roofs, flat roofs and walls, and Celotex insulation boards (now sold under the Sopratherm name, same boards) are our strongest price line. Popular sizes include:

• Celotex GA4000 100mm at £34.65 a sheet, the go-to for between rafters, floors and stud walls.
• Celotex GA4000 50mm at £21.03 a sheet, often used under rafters or as an over-layer.
• Celotex XR4000 150mm at £51.88 a sheet for deeper floor and roof build-ups.
• Celotex TB4000 25mm at £13.61 a sheet for thin layers and reveals.

Prices are ex VAT and correct at the time of writing; the product page always shows the current price. For other brands and thicknesses, browse all PIR insulation boards, including Kingspan, and use our PIR U-value calculator to check the thickness you need.

Common Norfolk projects and what to order

Period cottages and flint or solid walls

Many older Norfolk homes, from flint and brick cottages to Victorian terraces in Norwich, have solid walls with no cavity. Insulating on the inside with insulated plasterboard boards and insulates in one go: Celotex PL4000 37.5mm (25mm PIR + 12.5mm board) is £40.21 a sheet, and the full thermal insulated plasterboard range covers thicker options. Old solid walls often need to manage moisture, so deal with any damp first, take advice on vapour control and breathability for traditional construction, and check with your local authority if the building is listed or in a conservation area. See how to fit insulated plasterboard to a solid wall.

Barn conversions

Barn conversions usually mean insulating a large roof, new floors and walls from scratch, so PIR is the usual choice. Celotex GA4000 and XR4000 between and under rafters, and PIR boards over or under a floor insulation build-up, are typical. Your building control officer or designer will confirm the U-values the conversion must reach.

Lofts

For a straightforward loft top-up in a Norwich semi or a bungalow on the coast, loft insulation rolls laid to around 270mm are hard to beat. Knauf Loft Roll 44 Combi-Cut 200mm is £31.29 a roll. Read why 270mm is the usual target, and see the wider loft, roof and ceiling insulation range.

Cavity walls and new builds

For extensions and new builds around Wymondham, Dereham, Attleborough and the Norwich fringe, we stock full-fill mineral wool batts such as Knauf Insulation DriTherm 32 as well as PIR partial-fill boards. Browse the cavity wall insulation range and read our cavity wall insulation guide.

Plasterboard, drylining and ceilings

We supply plasterboard in standard, moisture resistant, fire resistant and acoustic grades, for example 12.5mm tapered edge plasterboard at £9.16 a sheet, plus drylining and metal framing. For offices, shops and commercial units in Norwich, Great Yarmouth or King's Lynn, we supply suspended ceiling tiles and grid. Our plasterboard calculator and suspended ceiling calculator work out quantities.

Building Regulations Part L

Approved Document L sets the energy efficiency standards for new work in England, including minimum U-values for walls, floors and roofs on extensions, conversions and new builds, and when you renovate or replace elements of an existing home. The thickness you need depends on the product, the construction and the type of work, so confirm the target with your designer or building control before ordering. Our insulation calculator helps with quantities.

Planning delivery in Norfolk

We deliver direct to your site or home by lorry, usually with a truck-mounted forklift to offload. We'll call you to arrange a delivery day.

• Rural lanes and farm sites: narrow lanes, soft verges, low bridges and gravel or grass drives are common in Norfolk. Tell us about access, weight limits and ground conditions when you order. The forklift needs firm, level ground.
• Norwich city streets: let us know about parking restrictions, permits or tight turns in older parts of the city.
• Storage: have a flat, dry, covered area ready, especially for plasterboard. Our delivery and storage checklist has the details.
• Someone must be there to receive the delivery, and we need a phone number for the driver.
