Celotex Insulation

Celotex provides a range of safe, reliable and high-quality insulation materials that are used to insulate countless homes and buildings all over the UK. Thousands of professionals choose Celotex to create environments that save energy every day. Insulation can help buildings reduce heat loss, which minimises the need for heating the building and therefore has less strain on the planet. In addition to this, Celotex manufactures its products with zero Ozone Depletion Potential. This is because they are environmentally conscious and provide innovative ways to help prevent global warming. As an approved supplier of insulation, we can offer our best possible prices. Why pay more when you can use Trade Insulations?

Builders love using Celotex as it is easy to install and cheap without sacrificing performance. Celotex saw its first big boost in popularity after WW2 when building materials were scarce. Since then, the products have improved and the brand has grown into the powerhouse that it is today. There are not many (if any) builders or property developers who have not heard of Celotex.

Most Celotex Insulation products are easy to cut to suit the application. In addition to this, Celotex installation is simple and can be achieved in multiple ways. The method of installation depends on the product or application. The insulation board may be mechanically fixed or installed using the dot and dab method. Insulation should be installed by a professional, however, Saint Gobain do provide handy installation guides. We suggest that you wear appropriate PPE and conduct risk assessments in order to minimise any potential health and safety risks.

Celotex by Saint Gobain

Celotex is an insulation brand by Saint Gobain. They manufacture a wide range of insulation products, which are suitable for a variety of applications. You may hear people refer to “Celotex” as a product rather than a brand. More often than not, when people ask for “Celotex”, they are requesting the general purpose PIR board range. This range consists of GA4000, XR4000 and TB4000 products. GA4000 boards are multi-purpose and therefore very popular. The 100mm variation of GA4000, which has the product code GA4100 is the most sold Celotex product. In addition to this, Celotex also manufactures cavity wall boards and insulated plasterboard.

The brand constantly provides new and innovative ways to insulate homes. They are constantly adapting to provide safer and more environmentally focused products. Every product has a handy product code assigned to it, which can help you to identify or search for the product you need. Celotex is affordable and provides excellent thermal performance.

Who Are Saint-Gobain?

Celotex Insulation is a brand of the company Saint-Gobain. Saint-Gobain is a company that designs and creates materials and distributes products. With Saint-Gobain dating back to over 350 years, it now has 180,000 employees in over 100 countries. Saint-Gobain is everywhere when it comes to our living spaces, transportation, and buildings. It can be found in many industrial applications and provides safe and reliable products meanwhile addressing climate change and supporting sustainable construction and resource efficiency.

Saint Gobain has partnered with Volvo, a leading automotive manufacturer. This partnership ensured a fleet of Saint-Gobain's delivery vehicles that deliver Celotex products throughout the UK were updated to help save up to 1,300 tonnes of carbon emission each year.

The new vehicles use a system called high-pressure direct ignition (HPDI), which allows them to reduce carbon emissions whilst maintaining performance. Volvo’s HPDI technology uses less fuel than a gas-only spark ignition system by creating an ignition cycle. This creates up to 20% fewer emissions than a standard diesel system. LNG engines emit significantly less CO2 per mile than the diesel equivalent. The vehicles are fuelled with bio-methane-based LNG from renewable sources making.

Celotex Insulated Plasterboard

PL4000

PL4000 is an innovative product, which merges PIR insulation with plasterboard. This can cut down install times as plasterboard and insulation is available in a single board.

The PL4000 insulated plasterboard can be used for use in roofs as well as internal wall lining applications.
