140mm Unilin Hyfloor XT/HYF Floor PIR Board

140mm Unilin Hyfloor XT/HYF insulation delivers an efficient solution for reducing downward heat loss in residential and commercial buildings. Floor insulation is critical to building performance, as uninsulated areas contribute substantially to thermal losses. This 140mm board achieves lower U-Values through optimised thickness and performance characteristics.

The 140mm XT/HYF Hyfloor excels with its outstanding thickness-to-performance ratio. This design allows you to meet Building Regulations' lower thermal targets whilst maintaining minimal board depth, delivering an efficient and reliable floor insulation solution.

Superior Thermal Performance and Reliable Installation:

The 140mm Hyfloor (T&G) represents a high-performance thermal insulation solution with an exceptional thickness-to-performance ratio. This board not only satisfies but exceeds the stringent thermal targets set by Building Regulations. The 140mm Unilin XT/HYF tongue and groove insulation board jointing system provides straightforward installation on-site, creating a robust and continuous insulation layer that effectively eliminates thermal bridging concerns.

Understanding Thermal Bridging:

Thermal Bridging occurs in small areas where the insulation level is reduced significantly, compared with the remainder of the element. They may be 'Repeating,' 'Random,' or 'Non-Repeating.'

Benefits of Proper Detailing:

1. Reduced risk of condensation and mould formation at poorly detailed junctions.
2. Enhanced energy efficiency with lower operational costs.
3. Cost-effective approach to achieving low energy building standards.
