What is Celotex insulation used for?

Celotex insulation boards are a versatile product that can be used in a variety of applications. Celotex products come in different sizes and thicknesses. Celotex is one of the most popular names in insulation. Below are some of the most frequently asked questions about Celotex:

What is celotex?

Celotex ltd is a leading manufacturer multi-purpose insulation boards that provides solutions for cold spots in walls, floors, roofs, cavities and many more areas. 

Though Celotex can be used by some people as a generic term for certain types of insulation boards, it is in fact a brand name for the manufacturer of the same name. It should come as no surprise then to learn that Celotex is one of the biggest names in the industry, and has been producing high quality insulation products for over 90 years.

Celotex boards are often PIR boards with foil facings to improve insulation levels.

Is Celotex polyisocyanurate (PIR)?

Buildings need insulation so they are not too hot or too cold. Polyisocyanurate is a type of plastic that is usually made into foam and used for insulation. Boards made out of plastic foam keep the heat in and the cold out. There are 3 kinds: Polyisocyanurate (PIR), phenolic foam, and extruded polystyrene.

Celotex insulation boards are manufactured from polyisocyanurate, and have low emissivity foil facings to aid with reducing heat transfer. The R-value denotes the resistance to heat flow – the higher the R-value the more insulating the product is.

A ‘standard’ large-format board - usually 2.4m in length by 1.2m in width - is extremely versatile. For applications where a large area needs to be insulated, like a floor, boards can be easily laid in a staggered pattern covering the majority of the surface area quickly. Being easy to cut, a larger board can be divided to neatly finish off a row of boards.

How effective is Celotex?

Celotex PIR insulation can withstand high humidity levels without deterioration. Celotex products are highly reflective and reflect more than 90% of radiant energy to outperform traditional insulation in high moisture locations.

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. Celotex is one of the few manufacturers that supply products to each of the UK building control specifications, as well as those from other countries.

Is Celotex GA4000 suitable for underfloor heating?

Celotex is a good choice for underfloor heating applications because it has excellent thermal insulation properties and Celotex does not absorb moisture. Celotex insulation can be used in heated or cooled areas, Celotex will maintain its efficiency to meet the changing demands of modern buildings.

What environmentally friendly insulation to replace celotex?

The most environmentally friendly insulation is probably something like sheep's wool or recycled denim. But they are not that practical in all situations. You need a much higher volume of material to provide the same level of insulation as a rigid foam board like celotex.

Is celotex environmentally friendly and what is celotex made from?

Celotex PIR insulation has been tested by BRE Global and has received an A+ rating in the BRE Green Guide, according to independent testing. In addition, Celotex's environmental impact is lower than that of other typical PIR manufacturers, according to the findings.

The BRE’s ‘Green Guide to Specification’  rates building materials according to their overall impact on the environment.

The Green Guide ratings are seen as a useful tool for comparing insulation materials since they are based on attaining a specified thermal value, which takes into account the fact that some insulation materials work differently and need greater thicknesses to achieve the same temperature. The Green Guide grades also take into consideration a comprehensive range of environmental impacts rather than just one or two issues

The Green Guide ratings do not always take the thickness of insulation into account, as one material may need to be thicker than another to achieve the set thermal value, which might necessitate other materials being thicker as well, increasing the overall construction's environmental impact.

Celotex PIR insulation is subjected to high temperatures throughout production, resulting in a greater U value and fire resistance. It's reusable, recyclable, water, vermin and rot-resistant.

At the same time, these rigid insulation boards are manufactured from petrochemicals, therefore they contain certain pollution threats as well as toxic emissions to water and air hazardous waste streams that must be kept within limits set by relevant laws.

The Celotex GA4000 boards are manufactured without any environmentally hazardous blowing agents.

Celotex is non toxic.  Celotex insulation contains no asbestos or formaldehyde and is not considered carcinogenic.

That said, Small particles of anything in your lungs can't be good and you can never be too careful. It is recommended that you use a mask when cutting. If you cut boards in a confined space, it is also good to use an air filter to avoid problems with the dust.

In conclusion, Celotex is a British company that produces high-quality building materials from sustainable resources for the construction industry around the world. Celotex distributes its products to over 70 countries worldwide. Celotex insulation boards are a safe, recyclable and environmentally friendly.
