Celotex provides a wide range of insulation boards for both commercial and domestic use, and it aids in the insulating of your structure, ensuring that heat loss is kept to a minimum while also maximizing energy efficiency. Celotex, a manufacturer of high-performing and high-quality insulation boards with over 90 years of expertise, seeks to not only create items that are highly insulating but also to satisfy present and future building codes as well as other carbon reduction programs. Celotex PIR boards are created to be one of the thinnest insulation boards on the market while yet maintaining excellent energy efficiency and U values. General-purpose insulation boards Celotex provides insulation boards for different things. They can be used in an outside wall, a roof, and more. Choose TB4000 for 12mm – 40mm thickness, GA4000 for 50mm – 100mm thickness or XR4000 for 110mm – 200mm thick general purpose insulation boards. Partial fill cavity wall insulation boards CW3000, previously known as CW400, is Celotex insulation board that has been specifically designed for partial fill cavity wall applications. CW3000 has been manufactured from rigid polyisocyanurate (PIR) using a blowing agent with zero ozone depletion potential, and low global warming potential. Underfloor heating insulation boards The Celotex FF4000 is a lightweight, versatile floor insulation board with enhanced strength to give improved stability and resistance to site traffic, as well as a foam structure for better pipe clip retention. Celotex FAQs What is Celotex made from? Celotex is a company that produces polyisocyanurate (PIR) foam board, which is a thermoset plastic in the form of foam. Celotex boards are frequently PIR boards with foil facings to boost insulating properties. Celotex boards are manufactured using a lamination technique, in which aluminum foil facings are flued together in a laminator and then blow injected to cause the glue to expand into foam. The end result is cut into boards. Celotex U-values The thermal performance of a material is determined by its U-value, which measures how well it insulates. The U value of a product varies considerably depending on where the product is utilized, the materials surrounding it, and more. For example, the Celotex 50mm U-value will differ based on the type of Celotex board being utilized and where it is installed. As a result, we utilize the Celotex R-value in our Celotex comparison chart because this parameter represents heat flow resistance. Click here for additional information on Celotex R values. How to cut Celotex It's possible to cut Celotex with a hand saw, but wear safety goggles or glasses while doing it. When cutting Celotex insulation, particles and dust are generated, so don't forget your respiratory protection. How to install Celotex installation boards There are a variety of Celotex installation methods, each with its own set of guidelines. Celotex can be installed between rafters in pitched roofs, as well as to ceilings in flat roofs, cavity walls, floors, and other surfaces. × OK

Celotex boards are frequently PIR boards with foil facings to boost insulating properties. Celotex boards are manufactured using a lamination technique, in which aluminum foil facings are flued together in a laminator and then blow injected to cause the glue to expand into foam. The end result is cut into boards. Celotex U-values The thermal performance of a material is determined by its U-value, which measures how well it insulates. The U value of a product varies considerably depending on where the product is utilized, the materials surrounding it, and more. For example, the Celotex 50mm U-value will differ based on the type of Celotex board being utilized and where it is installed. As a result, we utilize the Celotex R-value in our Celotex comparison chart because this parameter represents heat flow resistance. Click here for additional information on Celotex R values. How to cut Celotex It's possible to cut Celotex with a hand saw, but wear safety goggles or glasses while doing it. When cutting Celotex insulation, particles and dust are generated, so don't forget your respiratory protection. How to install Celotex installation boards There are a variety of Celotex installation methods, each with its own set of guidelines. Celotex can be installed between rafters in pitched roofs, as well as to ceilings in flat roofs, cavity walls, floors, and other surfaces. × OK

Underfloor heating insulation boards The Celotex FF4000 is a lightweight, versatile floor insulation board with enhanced strength to give improved stability and resistance to site traffic, as well as a foam structure for better pipe clip retention. Celotex FAQs What is Celotex made from? Celotex is a company that produces polyisocyanurate (PIR) foam board, which is a thermoset plastic in the form of foam. Celotex boards are frequently PIR boards with foil facings to boost insulating properties. Celotex boards are manufactured using a lamination technique, in which aluminum foil facings are flued together in a laminator and then blow injected to cause the glue to expand into foam. The end result is cut into boards. Celotex U-values The thermal performance of a material is determined by its U-value, which measures how well it insulates. The U value of a product varies considerably depending on where the product is utilized, the materials surrounding it, and more. For example, the Celotex 50mm U-value will differ based on the type of Celotex board being utilized and where it is installed. As a result, we utilize the Celotex R-value in our Celotex comparison chart because this parameter represents heat flow resistance. Click here for additional information on Celotex R values. How to cut Celotex It's possible to cut Celotex with a hand saw, but wear safety goggles or glasses while doing it. When cutting Celotex insulation, particles and dust are generated, so don't forget your respiratory protection. How to install Celotex installation boards There are a variety of Celotex installation methods, each with its own set of guidelines. Celotex can be installed between rafters in pitched roofs, as well as to ceilings in flat roofs, cavity walls, floors, and other surfaces. × OK

Celotex insulation boards have a long history of continuous product development and technical advancement in order to provide the best possible thermal performance. Celotex provides a wide range of insulation boards for both commercial and domestic use, and it aids in the insulating of your structure, ensuring that heat loss is kept to a minimum while also maximizing energy efficiency. Celotex, a manufacturer of high-performing and high-quality insulation boards with over 90 years of expertise, seeks to not only create items that are highly insulating but also to satisfy present and future building codes as well as other carbon reduction programs. Celotex PIR boards are created to be one of the thinnest insulation boards on the market while yet maintaining excellent energy efficiency and U values. General-purpose insulation boards Celotex provides insulation boards for different things. They can be used in an outside wall, a roof, and more. Choose TB4000 for 12mm – 40mm thickness, GA4000 for 50mm – 100mm thickness or XR4000 for 110mm – 200mm thick general purpose insulation boards. Partial fill cavity wall insulation boards CW3000, previously known as CW400, is Celotex insulation board that has been specifically designed for partial fill cavity wall applications. CW3000 has been manufactured from rigid polyisocyanurate (PIR) using a blowing agent with zero ozone depletion potential, and low global warming potential. Underfloor heating insulation boards The Celotex FF4000 is a lightweight, versatile floor insulation board with enhanced strength to give improved stability and resistance to site traffic, as well as a foam structure for better pipe clip retention. Celotex FAQs What is Celotex made from? Celotex is a company that produces polyisocyanurate (PIR) foam board, which is a thermoset plastic in the form of foam. Celotex boards are frequently PIR boards with foil facings to boost insulating properties. Celotex boards are manufactured using a lamination technique, in which aluminum foil facings are flued together in a laminator and then blow injected to cause the glue to expand into foam. The end result is cut into boards. Celotex U-values The thermal performance of a material is determined by its U-value, which measures how well it insulates. The U value of a product varies considerably depending on where the product is utilized, the materials surrounding it, and more. For example, the Celotex 50mm U-value will differ based on the type of Celotex board being utilized and where it is installed. As a result, we utilize the Celotex R-value in our Celotex comparison chart because this parameter represents heat flow resistance. Click here for additional information on Celotex R values.

Choose TB4000 for 12mm – 40mm thickness, GA4000 for 50mm – 100mm thickness or XR4000 for 110mm – 200mm thick general purpose insulation boards. Partial fill cavity wall insulation boards CW3000, previously known as CW400, is Celotex insulation board that has been specifically designed for partial fill cavity wall applications. CW3000 has been manufactured from rigid polyisocyanurate (PIR) using a blowing agent with zero ozone depletion potential, and low global warming potential. Underfloor heating insulation boards The Celotex FF4000 is a lightweight, versatile floor insulation board with enhanced strength to give improved stability and resistance to site traffic, as well as a foam structure for better pipe clip retention. Celotex FAQs What is Celotex made from? Celotex is a company that produces polyisocyanurate (PIR) foam board, which is a thermoset plastic in the form of foam. Celotex boards are frequently PIR boards with foil facings to boost insulating properties. Celotex boards are manufactured using a lamination technique, in which aluminum foil facings are flued together in a laminator and then blow injected to cause the glue to expand into foam. The end result is cut into boards. Celotex U-values The thermal performance of a material is determined by its U-value, which measures how well it insulates. The U value of a product varies considerably depending on where the product is utilized, the materials surrounding it, and more. For example, the Celotex 50mm U-value will differ based on the type of Celotex board being utilized and where it is installed. As a result, we utilize the Celotex R-value in our Celotex comparison chart because this parameter represents heat flow resistance. Click here for additional information on Celotex R values. How to cut Celotex It's possible to cut Celotex with a hand saw, but wear safety goggles or glasses while doing it. When cutting Celotex insulation, particles and dust are generated, so don't forget your respiratory protection. How to install Celotex installation boards There are a variety of Celotex installation methods, each with its own set of guidelines. Celotex can be installed between rafters in pitched roofs, as well as to ceilings in flat roofs, cavity walls, floors, and other surfaces. × OK

Partial fill cavity wall insulation boards CW3000, previously known as CW400, is Celotex insulation board that has been specifically designed for partial fill cavity wall applications. CW3000 has been manufactured from rigid polyisocyanurate (PIR) using a blowing agent with zero ozone depletion potential, and low global warming potential. Underfloor heating insulation boards The Celotex FF4000 is a lightweight, versatile floor insulation board with enhanced strength to give improved stability and resistance to site traffic, as well as a foam structure for better pipe clip retention. Celotex FAQs What is Celotex made from? Celotex is a company that produces polyisocyanurate (PIR) foam board, which is a thermoset plastic in the form of foam. Celotex boards are frequently PIR boards with foil facings to boost insulating properties. Celotex boards are manufactured using a lamination technique, in which aluminum foil facings are flued together in a laminator and then blow injected to cause the glue to expand into foam. The end result is cut into boards. Celotex U-values The thermal performance of a material is determined by its U-value, which measures how well it insulates. The U value of a product varies considerably depending on where the product is utilized, the materials surrounding it, and more. For example, the Celotex 50mm U-value will differ based on the type of Celotex board being utilized and where it is installed. As a result, we utilize the Celotex R-value in our Celotex comparison chart because this parameter represents heat flow resistance. Click here for additional information on Celotex R values. How to cut Celotex It's possible to cut Celotex with a hand saw, but wear safety goggles or glasses while doing it. When cutting Celotex insulation, particles and dust are generated, so don't forget your respiratory protection. How to install Celotex installation boards There are a variety of Celotex installation methods, each with its own set of guidelines. Celotex can be installed between rafters in pitched roofs, as well as to ceilings in flat roofs, cavity walls, floors, and other surfaces. × OK

Celotex FAQs What is Celotex made from? Celotex is a company that produces polyisocyanurate (PIR) foam board, which is a thermoset plastic in the form of foam. Celotex boards are frequently PIR boards with foil facings to boost insulating properties. Celotex boards are manufactured using a lamination technique, in which aluminum foil facings are flued together in a laminator and then blow injected to cause the glue to expand into foam. The end result is cut into boards. Celotex U-values The thermal performance of a material is determined by its U-value, which measures how well it insulates. The U value of a product varies considerably depending on where the product is utilized, the materials surrounding it, and more. For example, the Celotex 50mm U-value will differ based on the type of Celotex board being utilized and where it is installed. As a result, we utilize the Celotex R-value in our Celotex comparison chart because this parameter represents heat flow resistance. Click here for additional information on Celotex R values. How to cut Celotex It's possible to cut Celotex with a hand saw, but wear safety goggles or glasses while doing it. When cutting Celotex insulation, particles and dust are generated, so don't forget your respiratory protection. How to install Celotex installation boards There are a variety of Celotex installation methods, each with its own set of guidelines.

Underfloor heating insulation boards The Celotex FF4000 is a lightweight, versatile floor insulation board with enhanced strength to give improved stability and resistance to site traffic, as well as a foam structure for better pipe clip retention. Celotex FAQs What is Celotex made from? Celotex is a company that produces polyisocyanurate (PIR) foam board, which is a thermoset plastic in the form of foam. Celotex boards are frequently PIR boards with foil facings to boost insulating properties. Celotex boards are manufactured using a lamination technique, in which aluminum foil facings are flued together in a laminator and then blow injected to cause the glue to expand into foam. The end result is cut into boards. Celotex U-values The thermal performance of a material is determined by its U-value, which measures how well it insulates. The U value of a product varies considerably depending on where the product is utilized, the materials surrounding it, and more. For example, the Celotex 50mm U-value will differ based on the type of Celotex board being utilized and where it is installed. As a result, we utilize the Celotex R-value in our Celotex comparison chart because this parameter represents heat flow resistance. Click here for additional information on Celotex R values. How to cut Celotex It's possible to cut Celotex with a hand saw, but wear safety goggles or glasses while doing it. When cutting Celotex insulation, particles and dust are generated, so don't forget your respiratory protection. How to install Celotex installation boards There are a variety of Celotex installation methods, each with its own set of guidelines. Celotex can be installed between rafters in pitched roofs, as well as to ceilings in flat roofs, cavity walls, floors, and other surfaces. × OK

Celotex FAQs What is Celotex made from? Celotex is a company that produces polyisocyanurate (PIR) foam board, which is a thermoset plastic in the form of foam. Celotex boards are frequently PIR boards with foil facings to boost insulating properties. Celotex boards are manufactured using a lamination technique, in which aluminum foil facings are flued together in a laminator and then blow injected to cause the glue to expand into foam. The end result is cut into boards. Celotex U-values The thermal performance of a material is determined by its U-value, which measures how well it insulates. The U value of a product varies considerably depending on where the product is utilized, the materials surrounding it, and more. For example, the Celotex 50mm U-value will differ based on the type of Celotex board being utilized and where it is installed. As a result, we utilize the Celotex R-value in our Celotex comparison chart because this parameter represents heat flow resistance. Click here for additional information on Celotex R values. How to cut Celotex It's possible to cut Celotex with a hand saw, but wear safety goggles or glasses while doing it. When cutting Celotex insulation, particles and dust are generated, so don't forget your respiratory protection. How to install Celotex installation boards There are a variety of Celotex installation methods, each with its own set of guidelines. Celotex can be installed between rafters in pitched roofs, as well as to ceilings in flat roofs, cavity walls, floors, and other surfaces. × OK

Celotex FAQs What is Celotex made from? Celotex is a company that produces polyisocyanurate (PIR) foam board, which is a thermoset plastic in the form of foam. Celotex boards are frequently PIR boards with foil facings to boost insulating properties. Celotex boards are manufactured using a lamination technique, in which aluminum foil facings are flued together in a laminator and then blow injected to cause the glue to expand into foam. The end result is cut into boards. Celotex U-values The thermal performance of a material is determined by its U-value, which measures how well it insulates. The U value of a product varies considerably depending on where the product is utilized, the materials surrounding it, and more. For example, the Celotex 50mm U-value will differ based on the type of Celotex board being utilized and where it is installed. As a result, we utilize the Celotex R-value in our Celotex comparison chart because this parameter represents heat flow resistance. Click here for additional information on Celotex R values. How to cut Celotex It's possible to cut Celotex with a hand saw, but wear safety goggles or glasses while doing it. When cutting Celotex insulation, particles and dust are generated, so don't forget your respiratory protection.
