40mm Unilin XO/PR Pitched Roof Insulation Board

Discover the 40mm Unilin XO/PR Pitched Roof Insulation solution, engineered for sloped roofs. This advanced system delivers outstanding thermal performance whilst preserving your home's usable space. Roofs are critical to building integrity, yet they're a major source of heat loss. Installing 40mm XO/PR Pitched Roof Board significantly reduces heat escape and provides excellent thermal bridging solutions.

For complex roof designs with multiple slopes, the Warm Roof construction method is highly effective. This technique involves placing insulation above, or both above and between, the roof timbers. This keeps your building's structure aligned with interior conditions, reducing thermal stress and condensation problems.

Understanding Thermal Bridging

Thermal Bridging occurs in specific areas where insulation performance drops noticeably compared to the rest of the structure. These are classified as 'Repeating,' 'Random,' or 'Non-Repeating' occurrences.

Measuring Thermal Bridging

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

Why Good Detailing Matters

1. Prevents condensation and mould at poorly detailed junctions.
2. Creates more energy efficient buildings with lower running costs.
3. Offers a cost-effective route to achieving low energy standards.

Storage, Handling, and Cutting

1. Keep 40mm Unilin pitched roof insulation on a clean, level surface above ground and protected from weather.
2. Polythene wrapping alone won't protect against outdoor conditions.
3. Safeguard insulation during storage and construction work.
4. Always wear appropriate Personal Protective Equipment (PPE) when handling insulation.
