Celotex GA4000 thermal PIR insulation board (2023)

FAQs

What is the difference between Celotex XR4000 and GA4000? ›

What is the difference between Celotex TB4000, GA4000 and XR4000? There is no difference, they are the same boards, just different thickness groups.

Celotex GA4000 is an easy to install polyisocyanurate (PIR) insulation board with excellent thermal performance, featuring a low emissivity foil facing. Available in thicknesses from 50mm to 100mm, it can be considered for roof, wall and floor applications.

What to do when you can't buy PIR insulation boards. From time to time certain building materials can fall into short supply. This can be for a number of reasons, such as the housing market is booming and factories just have not got the extra capacity to cope with the increase in production.

"Celotex XR4000 is an easy-to-install polyisocyanurate (PIR) insulation board with excellent thermal performance, low emissivity foil facings, and a low global warming impact, suitable for roof, wall, and floor applications." In other words, they are all the same item.

Both Rockwool products and Celotex provide good thermal insulation, however if it is solely thermal which is required then Celotex may be the better option, as it has a better thermal performance. However Rockwool products have much better sound-absorbing and fire-resistant properties.

Celotex is a fairly top-end product in terms of price, but the varying thicknesses and sizes make it difficult to confirm a specific amount. The higher cost is largely due to the foam and difficulty in manufacturing this type of board. Of course, you will need a reliable supplier.

It's essential to create a space between your Celotex boards and the roof itself, to allow air to circulate. This will then help prevent damp and condensation, and in turn, mould. A sensible air gap, we would recommend, is somewhere around 25mm-50mm.

Celotex does need a vapour barrier, as a vapour barrier will help to prevent moisture and air from seeping through the wallboard and into the insulation.

How Long Does Celotex Last? Celotex, if left undisturbed once installed can be expected to last around 60 years.

At the time of writing in mid-2021, PIR insulation has seen a number of price increases linked to the supply of raw materials required to manufacture it. In addition, issues with the transportation of those raw materials have affected the availability of PIR in the UK market.

What is better than PIR insulation? ›

While PIR and PUR have been used for decades, there's another advanced insulation that outshines both in fire protection and thermal performance: Kingspan's QuadCore Technology. With 11 percent better thermal performance than PIR and up to 60 percent improvement over PUR, it is unrivaled in the market.

How long does PIR Insulation (Eurothane GP) last? It doesn't degrade over time so continues to give you the same outstanding insulating performance to last the lifetime of the building. Also because it is a ridged board it will not sag or move once installed, as this can cause insulation voids in the building envelope.

Some of the best PIR thermal insulation board solutions currently on the market come from the likes of Celotex, Recticel, EcoTherm, IKO, Xtratherm and Kingspan. Let's take a closer look at their respective performances. Keep in mind that the higher the R-value of insulation the better its thermal performance.

The subsidiary was formed to manufacture Celotex fiberboard insulation at a facility in Marrero, Louisiana. Celotex Company of Great Britain was founded in 1925, and only this arm of the company still exists today as a brand of Saint-Gobain.

Celotex boards are a top choice for insulation because they offer a superior combination of thermal, acoustic and fire performance. Celotex products have been successfully tested in accordance with UK building regulations.

If you are looking for a thermal insulation that is significantly cheaper than Celotex, you could use EPS Polystyrene. Quinn Therm has an extensive range of PIR insulation products with top-performing thermal conductive properties for use in floors, roofs and walls.

Polyisocyanurate: Known as polyiso for short, polyisocyanurate foam has the highest R-value per inch (R-6.5 to R-6.8) of any rigid insulation.

Aerogel is more expensive, but definitely the best type of insulation. Fiberglass is cheap, but requires careful handling. Mineral wool is effective, but not fire resistant. Cellulose is fire resistant, eco-friendly, and effective, but hard to apply.

Celotex manufactured asbestos insulation and construction materials from the 1920s to the 1980s, and it operated an asbestos mine until 1986. Asbestos litigation forced the company into bankruptcy in 1990.

Can I still use it? Yes, the insulation is open cell meaning that it will allow air movement through it. The product will therefore dry out and can be used as long as it has not been damaged.

Is Celotex harmful to breathe in? ›

Celotex products are considered to be non-hazardous and have no known toxic effects. However, inhaling dust should be avoided. Celotex products should always be handled and used in accordance with good occupational hygiene and safety practices.

Insulation boards by Celotex can be installed in pitched roofs, flat roofs, solid masonry walls and more.

Correct installation of the Celotex board

The Celotex board must be installed as tightly as possible between the joists and secured with screws or nails.

This board is not suitable to walk directly over. Celotex would require a chipboard or OSB board to be placed over the top, which would spread any weight evenly and protect the board from getting damaged.

These boards are available in thicknesses ranging from 25mm (37.5mm) to 65mm (77.5mm) with each insulation board bonded to a 12.5mm thick plasterboard. The PL products are high-performance boards generally applied to wall applications.

When Celotex is fitted between roof rafters, you need to ensure you leave an air gap of roughly 25mm – 50mm between the Celotex boards and the roof itself. This is to ensure air can circulate freely and to avoid damp or condensation.

The chipboard should be glued with appropriate adhesive and use temporary edges to provide a gap of around 10 to 12mm to allow expansion.

TB4000 can be used for overcoming thermal bridging and for use in two layer build ups including between and under rafters and over stud in timber frame wall lining applications.

Spray Foam (Polyurethane Foam)

Spray foam insulation is one of the most durable, effective, and reliable forms of home insulation. It can last a lifetime or longer. Because it is mold resistant and does not hold moisture, it doesn't move around and typically stays put until physically removed.

Phenolic board would typically provide an R-value of around 5.0. The PIR or PUR board would typically provide an R-value of around 4.5.

Is PIR the best insulation? ›

Polyisocyanurate (PIR) is one of the most efficient insulation material used in construction. PIR insulation provides acoustic and thermal properties, rigidity, durability and excellent compressive strength.

The recommended thickness for PIR insulation in walls is typically around 125mm to achieve the recommended U-value of 0.17 W/m2K. The recommended thickness for PIR insulation in roofs is typically around 140mm to achieve the recommended U-value of 0.16 W/m2K.

Drawbacks or disadvantages of PIR sensor

➨They have lower sensitivity and less coverage compare to microwave sensors. ➨It does not operate greater than 35 degree C. ➨It works effectively in LOS (Line of Sight) and will have problems in the corner regions. ➨It is insensitive to very slow motion of the objects.

Can I walk on Deck-VQ^® vacuum insulation panels? Yes, this is possible due to the protection layers in high density PIR and the compressive strength of 150 kPa (CS(10\Y)150).

Three types of PIR Insulation Boards available in different thicknesses, 12mm-45mm, 50mm-100mm and 110-150mm, all especially designed to eliminate thermal bridges, very easy to cut and shape and energy-efficient.

The maximum operational temperatures for PUR and PIR are +100°C and +150°C respectively.

The temperature must exceed 250°C for a period of time before the occurrence of degradation, which may lead eventually to self-ignition. At this temperature most solid combustible material will exhibit signs of charring, one of the first steps in ignition.

The ability of PUR/PIR insulation to resist water and to quickly revert to former performance after exposure to excess moisture makes it a preferred choice for flood resilient building.

This gap provides ventilation and prevents moisture buildup, which can lead to mould and other problems. Insulation boards are no exception to this rule, and it's important to leave an air gap between them and the surface they're installed on.

Celotex GA4000 insulation boards do not catch fire easily and have a class 1 fire rating. They do not break easily and are apt for tough usage in spite of their lightweight and flexible character.

What is the difference between Rockwool and PIR? ›

Rockwool has a lower thermal insulating power. In other words, one will need more Rockwool to have the same insulation of PUR and PIR foams. What does that mean? It means that one can replace 50mm of PUR or PIR insulation with an 80mm Rockwool sandwich panel.

Note that this product is styrofoam - that is a different material, it is NOT a polyisocyanurate foam board.

Our Celotex PIR insulation is manufactured at two production facilities, Hadleigh in Suffolk and Eggborough in Yorkshire. While our ISOVER mineral wool insulation is manufactured from Runcorn in Cheshire.

The company continues to produce Regular Insulation Sheathing as a 1/2-inch thick insulating board with an R-value of 1.2. Celotex Regular Insulation Sheathing is described in contemporary product literature as: Produced from cellulosic interlaced fiber bond with natural binders.

The best insulation for walls depends on many circumstances. However, for open walls where budget is not a concern, spray-foam insulation typically delivers the highest resistance of heat flow.

Rigid foam board insulation is available in many materials, including polystyrene (R-3.8 to R-5.0), polyurethane (R-5.5 to R-6.5) and polyisocyanurate (R-5.6 to R-8.0). Since it has the highest R-value, rigid foam is typically reserved for foundations and basement walls.

Celotex is also effective in reducing noise pollution and keeping your home cooler in the summer and warmer in the winter. Celotex PIR insulation offers great thermal protection. If you are looking for an acoustic insulation, then Rockwool insulation is excellent at providing that.

Celotex GA4000 insulation boards do not catch fire easily and have a class 1 fire rating. They do not break easily and are apt for tough usage in spite of their lightweight and flexible character.

Is Celotex the best? ›

Celotex boards are a top choice for insulation because they offer a superior combination of thermal, acoustic and fire performance.

When cutting Celotex insulation, dust extraction equipment, eye protection and face masks should be provided. Dust or particles in the eyes should be washed out with liberal quantities of water. If skin is sensitive to fibre irritation, apply a barrier cream to exposed areas before handling.

It achieves a classification of E. In layman's terms, this means it is combustible and will contribute to the overall fire load.

Celotex Asbestos Settlement Trust

Eventually, the amount of money Celotex was expected to pay to asbestos victims overwhelmed the company. It filed for Chapter 11 bankruptcy protection in 1990. It reorganized and emerged in 1996. Celotex Asbestos Settlement Trust.
