Celotex is renowned for its range of reliable and high-quality insulation solutions, and their Floor Insulation category is no exception. The selection primarily includes the GA4000, TB4000, and XR4000 series, available in various thicknesses to cater to different insulation needs.

GA4000 Series

The GA4000 General Purpose PIR Insulation Boards are versatile, suitable for a variety of flooring applications, and come in dimensions of 2.4m x 1.2m. With options from 50mm to 100mm, they are ideal for projects that require robust insulation with minimal thermal bridges.

TB4000 Series

Celotex's TB4000 Thermal Bridging Boards are designed to target thermal bridging areas, with thicknesses ranging from 12mm to 40mm. These boards are perfect for enhancing the thermal performance of your floor system, especially in junctions and hard-to-insulate spots.

XR4000 Series

The XR4000 Insulation Board series offers a solution for higher load-bearing requirements, available in thicknesses up to 200mm. These are particularly well-suited for floors that need to support heavier loads while providing superior insulation.

Specialty Options

For specialised applications, Celotex offers the CW4000 and PL4000 series, which come in various thicknesses and are tailored for cavity walls and plaster-laminated insulation needs, respectively. These products can complement floor insulation systems in more comprehensive building insulation strategies.

When selecting the appropriate Celotex insulation for your flooring, consider the thermal requirements, load-bearing capacity, and whether the insulation will encounter significant thermal bridging. Celotex's range in the Floor Insulation category ensures that whether you're insulating a residential property or a commercial building, you'll find the right fit for your project.
