80mm Unilin Xtroliner XO/UF PIR Floor Insulation

80mm Unilin Xtroliner XO/UF PIR Floor Insulation Board delivers outstanding thermal performance for underfloor applications. With a thermal conductivity of just 0.021 W/mK, this floor insulation solution effectively reduces heat loss through the floor structure.

Installing 80mm XO/UF Underfloor insulation significantly improves U-Values in both new and existing floor systems. The product combines lightweight construction with easy installation, whilst maintaining excellent compressive strength and minimal thermal conductivity. This makes it an ideal choice for meeting floor insulation requirements.

Fabric Energy Efficiency is based on 3 main principles:

1. U-Values
2. Thermal Bridging
3. Air tightness

What is Thermal Bridging?

Thermal Bridging occurs in localised areas where insulation levels drop significantly compared to the surrounding structure. These instances can be categorised as 'Repeating,' 'Random,' or 'Non-Repeating.'

How is Thermal Bridging quantified?

Thermal bridges are measured using linear thermal transmittance, known as PSI (Ψ), measured in W/mK. SAP is the software tool used to calculate a building's energy performance rating. Within this system, thermal bridging effects at junctions are represented by a 'Y-Value.'

Note

80mm Unilin XO/UF offers one of the most effective floor insulation solutions available. It provides the strength and thermal performance needed to achieve the high-performance U-Values required by Building Regulations.
