Celotex is renowned for its high-quality insulation solutions, providing a range of products to suit various applications in both residential and commercial buildings. Their insulation boards are designed to offer enhanced thermal efficiency, contributing to the energy efficiency of buildings and helping to reduce heating costs.

General Purpose PIR Insulation Boards

Celotex GA4000 series are versatile general-purpose PIR insulation boards suitable for floors, walls, and roofs. These come in standard dimensions of 2.4m x 1.2m, catering to a wide range of thicknesses to fit different insulation requirements.

Insulated Plasterboard

The PL4000 series combines insulation with plasterboard, ideal for dry lining applications. This two-in-one product simplifies installation while providing thermal insulation and a ready-to-decorate surface.

Thermal Bridging Boards

Celotex TB4000 series address thermal bridging, offering a solution to prevent heat loss where different building elements meet. These boards can be used in various applications to enhance the thermal performance of the building envelope.

High-Performance Insulation Boards

The XR4000 series is designed for situations requiring high-performance insulation with greater thicknesses. These boards are suitable for projects demanding a lower U-value and can be used in multiple building areas, including challenging spaces.

Cavity Wall Insulation

Celotex offers products specifically designed for cavity walls, such as the CW4000 and Thermaclass Cavity Wall 21, providing an effective way to insulate new and existing cavity walls to improve thermal performance.

Choosing the Right Celotex Insulation

Selecting the appropriate Celotex product depends on the specific use case:

  • For general applications: GA4000 series is a flexible choice.
  • For dry lining: PL4000 series is the best option.
  • To combat thermal bridging: TB4000 series is recommended.
  • For high-performance needs: XR4000 series is ideal.
  • For cavity walls: CW4000 or Thermaclass Cavity Wall 21 will serve well.

     

Remember to consider the specific dimensions and thicknesses required for your project, as these will impact the insulation's thermal efficiency and how it fits within your building's structure.

Installation and Environmental Considerations

All Celotex products are designed for ease of installation. However, it's crucial to follow the manufacturer's guidelines to ensure optimal performance. Additionally, Celotex is committed to sustainability, with products designed to reduce carbon footprints and enhance energy efficiency in buildings.
