Unilin Xtroliner XO/UF 25mm PIR Floor Insulation

25mm Unilin Xtroliner XO/UF PIR Floor Insulation Board offers outstanding performance when installed beneath flooring. With a PIR composition, this product delivers superior floor insulation with an impressive thermal conductivity rating of just 0.021 W/mK. Floors are typically responsible for significant heat loss, which makes proper insulation essential for any building.

Installing 25mm XO/UF Underfloor insulation dramatically improves the U-Value performance of both new and existing floor systems. Combining lightweight construction with simple fitting procedures, this product also features excellent compressive strength and low thermal conductivity. The result is a premium solution for all your floor insulation needs.

Fabric Energy Efficiency is based on 3 main principles:

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

What is Thermal Bridging?

Thermal Bridging takes place within limited zones where insulation is notably diminished in comparison to the surrounding element. These occurrences can be classified as 'Repeating,' 'Random,' or 'Non-Repeating.

How is Thermal Bridging quantified?

Thermal bridges are evaluated using a linear thermal transmittance measurement known as PSI (Ψ), expressed in W/mK. SAP serves as the software application employed to determine a building's energy rating. Within this software, the impact of Thermal Bridging at intersections is represented by a 'Y-Value.

Note

The 25mm Unilin XO/UF represents one of the most efficient approaches to floor insulation. It delivers the strength and thermal performance needed to achieve the high-performance U-Values required by current Building Regulations.
