Insulation4Less proudly presents an extensive range of Celotex Floor Insulation products, curated meticulously to meet the diverse needs of our clientele. Famed for its stellar reputation in providing high-quality Polyisocyanurate (PIR) insulation boards, Celotex offers a versatile collection ensuring top-tier thermal performance across a spectrum of floor insulation applications.

General Purpose PIR Insulation Boards

The Celotex GA4000 Series, encompassing various thickness options like 25mm, 50mm, 60mm, 70mm, 75mm, 80mm, 90mm, and 100mm, serves as a one-stop solution for multiple applications, including roof, wall, and floor insulation. These general-purpose boards are well-regarded for their:

  • Versatility: Capable of meeting U-value requirements when used singularly or in combination.
  • Thermal Efficacy: High performance in varied temperature scenarios.
  • Ease of Installation: Lightweight and simple to fit.

Utilise GA4000 series for floating floors, solid floors, and timber floors, ensuring an envelope of energy-efficient insulation across your build.

Premium Performance PIR Insulation

The Celotex XR4000 Series, available in substantial thicknesses like 110mm, 120mm, 130mm, 140mm, 150mm, 165mm, and up to 200mm, might just be your go to. Its robustness and premium thermal efficiency make it apt for:

  • Hefty Applications: Particularly suitable for projects demanding high thicknesses without compromising on performance.
  • Specialised Uses: Ideal for heavy-duty floor insulation applications where higher thermal resistance is paramount.

These boards, due to their thickness and thermal capabilities, stand out for applications in larger construction or industrial spaces.

High Performance Thin Insulation

The Celotex TB4000 Series, available in slender profiles like 12mm, 20mm, 25mm, 30mm, and 40mm, provide exceptional solutions when minimal intrusion into floor space is crucial. Some characteristics and uses include:

  • Space Efficiency: Optimal for situations where installation space is restricted.
  • Enhanced Thermal Bridging: Assists in reducing thermal bridges due to its slim profile.

This series adeptly complements applications where space conservation and enhanced thermal bridging are crucial, such as underfloor heating systems or upper floor levels in residential settings.

How to Choose the Right Celotex Insulation

Selecting the optimal Celotex insulation entails considering various factors:

  • U-Value Requirements: Ensure your choice meets the U-value requirements set by building regulations.
  • Application Type: Differentiate whether the application is for a new build, retrofit, or a specific installation like underfloor heating.
  • Floor Type: Consider whether the floor is solid, suspended, or a different type, as this influences the insulation method.
