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 is significantly reduced compared to the surrounding structure. These situations 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 used to calculate a building's energy performance rating. Within this system, the effect of Thermal Bridging at junctions is shown by a 'Y-Value.'

Note

50mm Unilin XO/UF offers one of the most effective floor insulation solutions available. It delivers the strength and thermal characteristics needed to achieve the high-performance U-Values required by Building Regulations.
