75mm Unilin Xtroliner XO/SK Warm Roof Board

75mm Unilin Xtroliner XO/SK Warm Roof Board (Tongue & Groove) is a thoughtfully engineered external roof insulation solution with robust facings that lock together securely. This product delivers an impressive passive U-value of 0.15 W/m²K. Choosing 75mm XO/SK roof insulation brings noticeable improvements to architectural detail, faster installation times, and a level surface for precise finishing work.

A warm roof design cuts down the number of thermal bridging points across your roof, which means better overall thermal performance. The product carries a Euroclass C Fire Insulation Classification.

What constitutes Thermal Bridging?

Thermal bridging occurs in specific areas where insulation levels drop noticeably compared to the rest of the building. These situations fall into 'Repeating,' 'Random,' or 'Non-Repeating' categories.

How is Thermal Bridging Quantified?

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

Good detailing delivers benefits

1. Less chance of condensation and mould forming at poorly detailed junctions.
2. More energy efficient building with lower running costs.
3. A more cost effective method of achieving a low energy building.

Guidelines for Handling, Cutting, and Storage

1. Store Unilin 75mm PIR insulation board on a clean, level surface away from the ground in a sheltered location.
2. Polythene wrapping alone doesn't provide sufficient protection from weather exposure.
3. Protect the insulation during storage and throughout the build process.
4. Always wear appropriate Personal Protective Equipment (PPE) when handling insulation materials.
