120mm Unilin XO/PR Pitched Roof Insulation Board

Discover the 120mm Unilin XO/PR Pitched Roof Insulation solution designed for sloped roofs. This advanced system delivers outstanding thermal performance whilst preserving your usable interior space. Roofs are critical to any building's thermal envelope, and heat loss through them can be substantial. Installing 120mm XO/PR Pitched Roof Board effectively reduces heat escape and provides excellent thermal bridging control.

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 structure closer to internal temperatures, reducing thermal stress and condensation problems.

What constitutes Thermal Bridging?

Thermal Bridging occurs in specific areas where insulation performance drops noticeably compared to the rest of the building envelope. These can be classified as 'Repeating,' 'Random,' or 'Non-Repeating' types.

How is Thermal Bridging Quantified?

Thermal bridges are measured using linear thermal transmittance, expressed as PSI (Ψ) in W/mK. The SAP software programme calculates a building's energy performance and includes thermal bridging assessment at junctions, shown as a 'Y-Value.'

Good detailing delivers benefits

1. Lower risk of condensation and mould at poorly designed junctions.
2. More efficient buildings with reduced energy bills.
3. Cost-effective approach to achieving low-energy building standards.

Handling, Cutting, and Storage Guidelines

1. Keep 120mm Unilin pitched roof insulation on a dry, level surface above ground, protected from weather.
2. The polythene wrapping provides limited protection against outdoor conditions.
3. Protect insulation during storage and on-site construction work.
4. Always use appropriate Personal Protective Equipment (PPE) when handling insulation materials.
