Discover the 25mm Unilin XO/PR Pitched Roof Insulation solution designed for sloped roofs. This advanced system delivers excellent U-Values whilst protecting your usable interior space. Roofs are critical to any building's thermal envelope, and heat loss through this area can be substantial. Installing 25mm XO/PR Pitched Roof Board effectively reduces heat escape and provides outstanding Thermal Bridging performance.
For complex roof designs with multiple slopes, the Warm Roof construction technique is highly effective. This method places insulation above, or both above and between, the roof timbers. This keeps your building's structural elements at temperatures closer to your indoor environment, reducing thermal stress and condensation problems.

Thermal Bridging occurs in specific areas where insulation performance drops noticeably compared to surrounding sections of the building envelope. These can be classified as 'Repeating,' 'Random,' or 'Non-Repeating' thermal bridges.
Thermal bridges are measured using linear thermal transmittance, expressed as PSI (Ψ) in W/mK. The SAP software programme calculates building energy efficiency ratings and includes thermal bridge assessment at junctions, shown as a 'Y-Value.'
