75mm Unilin Safe-R SR/PR Phenolic Roof Insulation Board

Discover the 75mm Unilin Safe-R SR/PR Phenolic Roof Insulation Board – an excellent choice for sloped roofs in ventilated, hybrid, or warm configurations. This premium solution delivers outstanding thermal performance with minimal impact on your interior space. Roof Insulation is essential for controlling heat loss, as roofs represent one of the most vulnerable areas in any building. The 75mm SR/PR specification effectively reduces thermal loss whilst providing superior thermal bridging control.

Warm Roof construction proves particularly valuable for complex roof geometries. When insulation is positioned above or between the roof timbers, the building envelope stays aligned with internal conditions. This strategy substantially decreases thermal stress and condensation risks.

Integral vapour control layer

1. For conventional ventilated roof designs, maintain a 50mm clear ventilation gap between the insulation and roofing felt. Where a vapor-permeable roof membrane is specified, this gap may be reduced or removed entirely. Always consult the membrane manufacturer's technical guidance for specific requirements.
2. Standard ceiling layouts typically position fiberglass insulation between and over joists, which obscures the upper joist sections and creates access difficulties. Applying SR/PR to the underside before fitting plasterboard addresses thermal bridging whilst keeping joists visible and accessible. Alternatively, Safe-R SR/TB Drylining boards offer a practical solution, enabling safe roof space access and storage capability.

Handling, Cutting, and Storage:

1. Store Unilin pitched roof insulation on a clean, level, raised surface and protect it with a weatherproof cover.
2. Polythene wrapping alone cannot provide adequate weather protection.
3. Prevent damage during storage and on-site handling.
4. Always use appropriate personal protective equipment (PPE) when working with insulation.

Certification and Standards:

1. BBA Certification Number: 10/4803.
2. Compliance with BS EN ISO 9001 Quality Management System.
3. Adherence to BS EN ISO 14001 Environmental Management System.
4. Conformance with BS EN 13166 standards.
