Unilin Xtroliner XO/UF 100mm PIR Floor Insulation

100mm Unilin Xtroliner XO/UF PIR Floor Insulation Board delivers outstanding performance for underfloor applications. With a thermal conductivity of just 0.021 W/mK, this floor insulation solution significantly reduces heat loss through your floors. Most buildings lose considerable warmth at ground level without proper insulation protection.

Installing 100mm XO/UF Underfloor insulation dramatically improves U-Values in both new and existing floor systems. Combining lightweight construction with easy fitting, this product offers excellent compressive strength and minimal heat transfer. The result is a premium floor insulation choice that meets modern building standards.

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 specific areas where insulation levels drop significantly compared to adjacent sections. These situations can be described 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 shown as a 'Y-Value.'

Note

100mm Unilin XO/UF represents one of the most effective floor insulation solutions available. It delivers the strength and thermal performance needed to achieve the demanding U-Values required by current Building Regulations.
