Our Expert Says

Choose 60mm Celotex GA4060 when 50mm leaves you just short of the U-value you are chasing but you still want a slim, easy-to-handle board. Sitting one step up in the general-purpose GA4000 range, it lifts thermal resistance to 2.70 m²K/W while keeping the same rigid polyisocyanurate (PIR) core and low-emissivity foil facings. It is a sensible pick for timber-framed walls, internal dry lining and floor build-ups where a moderate gain in performance is worth the extra 10mm. Light to carry, quick to cut and equally at home on new build or refurbishment. Click for our full review

Product Description

60mm Celotex GA4060 PIR Insulation Board is a rigid polyisocyanurate (PIR) insulation board from the general-purpose GA4000 range, sitting one step above the 50mm board in thermal performance. It is designed for use across walls, floors and roofs, and is a common choice where a 60mm board is specified, or where 50mm falls just short of the required thermal resistance.

Each board measures 2400mm x 1200mm x 60mm and is sold individually, covering 2.88m² per board. It carries a declared thermal conductivity of 0.022 W/mK and a thermal resistance of 2.70 m²K/W, a useful uplift over the 50mm board that still keeps the insulation layer slim while moving a build-up closer to its target U-value.

At the core of the board is a closed-cell PIR foam, faced on both sides with a low-emissivity aluminium foil. That foil does more than protect the core: where it faces a sealed or cavity air space, the reflective surface lifts the thermal performance the build-up can achieve. The straight, square edges let boards sit flush against one another, so joints stay tight and the insulation layer reads as continuous across walls, floors and roofs.

In practice, 60mm GA4060 is specified in timber-framed walls, internal dry lining to masonry, suspended timber and concrete floors, and pitched roofs between or under rafters, with flat-roof build-ups also within the GA4000 range's scope. As with any PIR board, it should be fitted in line with the latest Celotex technical guidance, the project specification and current Building Regulations, including the height restriction on external wall use. That versatility is the point: one board type carries across several elements of a project, on new build and refurbishment alike.

Key Benefits of 60mm Celotex GA4060:

  • 60mm rigid polyisocyanurate (PIR) insulation board from the multi-application GA4000 range, for walls, floors and roofs.
  • Thermal resistance (R-value) of 2.70 m²K/W, a step up from the 50mm board.
  • Declared thermal conductivity of 0.022 W/mK for efficient performance in a slim board.
  • Low-emissivity aluminium foil facings on both sides, lifting performance against sealed and cavity air spaces.
  • Straight, square edges for tight joints and a continuous insulation layer.
  • Rigid yet light, so boards are simple to transport, handle and cut on site with standard tools.
  • Closed-cell PIR core with good resistance to moisture pick-up.
  • Manufactured with a blowing agent of zero Ozone Depletion Potential (ODP) and low Global Warming Potential (GWP), free of CFCs and HCFCs.
  • Supplied as a single 2400mm x 1200mm board covering 2.88m².
  • BBA certified (Certificate 25/7318) for defined pitched roof, dry lining and floor applications.

Good to know:

  • Boards measure 2400mm x 1200mm and are sold individually, each covering 2.88m².
  • The foil facing is printed on one side only: fit the board with the plain face towards the cavity to achieve the rated thermal performance.
  • Where a project needs more than 60mm, GA4060 can be combined with other thicknesses to build up to a target U-value.
  • Celotex GA4000 should not be used in the external walls of buildings over 11 metres in height; check current Building Regulations for your project.
  • PIR is moisture resistant but not waterproof: keep boards dry on site and store them flat, off the ground and out of prolonged sunlight.
  • Insulation UK offers a bespoke cutting service, so boards can be supplied cut to your sizes to reduce waste and on-site mess.
  • The U-value of the finished element depends on the full build-up, not the board alone: confirm the target for your application before ordering.

A measured step up from the entry-level board, 60mm Celotex GA4060 adds useful thermal resistance without adding bulk, keeping specification simple and installation quick across walls, floors and roofs.

Product FAQs

Why does Celotex start with TB GA & XR? What do they mean?

Celotex comes in a range of thicknesses from 20mm to 200mm. These are the same boards made from PIR and foil backed. Celotex have put them into ranges to help you decide what thickness may be more suitable for your application, however you may have been given a specific U value you need to meet or been advised. If you are unsure, please contact our technical team sales@insulationuk.co.uk

TB4000

TB stands for thermal bridging, which is areas prone to cold spots & heat loss. Thickness ranges from 20mm to 40mm, ideal for tight spaces or for a multi layer build up.

GA4000

Is for general applications - ranging from 50mm to 100mm in thickness, these boards are more commonly used in walls, but are suitable for floors and pitched roofs. GA4100 100mm PIR insulation is perhaps the best selling thickness in this range.

XR4000

Stands for extra resistance, ranging from 110mm to 150mm this insulation is idea for when space isn't a restriction and where a superior thermal efficiency is required.

What do the numbers mean in Celotex PIR insulation for example TB4020 or GA4100 or XR4200

The 4000 is the range name given to Celotex PIR - so to differentiate between the thicknesses the coding starts with 4 to tell you the Celotex range then the thickness of the insulation is the preceding number.

4020 - 4000 range 20mm thickness

4075 - 4000 range 75mm thickness

4150 - 4000 range 150mm thickness

Hi do I calculate a U value?

U-values are determined for various building elements, including walls, floors, roofs, windows, and door and calculating U values can be daunting. There are several factors to include, especially where the insulation will be installed. There are calculators available, but our technical team can help call us on 03003 034 578.

What is the R-value of 60mm Celotex?

60mm Celotex GA4060 has a thermal resistance (R-value) of 2.70 m²K/W, based on its 60mm thickness and a declared thermal conductivity of 0.022 W/mK. Use the R-value to compare thicknesses; the U-value of the finished element depends on the full build-up, so check your project specification before ordering.

Is 60mm insulation enough?

It depends on what you are insulating and the U-value you need to hit. At 60mm, GA4060 provides a thermal resistance of 2.70 m²K/W, which can be sufficient on its own where space is tight or where it forms one layer of a larger build-up. Lower U-value targets, for example in many roofs and floors, often call for a thicker board or an additional layer. Confirm the target U-value for your specific element before ordering, and the Insulation UK team can help you size it.

Thermal Performance

Thermal performance helps show how effectively the product reduces heat transfer.

Thermal conductivity measures how readily heat passes through the material, so lower figures generally indicate better insulating performance.

R Value shows the material’s thermal resistance at that thickness, so higher figures generally mean stronger insulation performance.

These figures relate to the insulation product itself and should be considered alongside the full wall, roof or floor build-up when checking project requirements.

Thermal Conductivity:
0.022 W/mK
R Value:
2.7 M²K/W
Physical Properties

Compressive strength shows how well a product resists being squashed under pressure.

The figure is measured in kPa, which stands for kilopascals.

A higher kPa number means stronger resistance to compression. For example, 120 kPa offers more compression resistance than 70 kPa, but less than 150 kPa, 200 kPa or 300 kPa.

This does not mean the product can carry that load on its own. It should always be checked as part of the full floor, wall, roof or system build-up.

Compressive Strength:
140 kPa
Fire Performance

Euroclass reaction to fire is the European EN 13501-1 classification used to show how a construction product behaves when exposed to fire.

The main scale runs from A1 and A2 at the highest end, through B, C, D and E, down to F.

A1 is non-combustible and A2 is limited combustibility, while lower classes indicate a greater contribution to fire.

Euroclass F is the lowest rating on this scale and indicates the weakest reaction-to-fire performance.

This is different from fire resistance, which relates to how long a complete wall, floor or roof build-up can resist fire.

Reaction to Fire:
Euroclass F
