Unilin Safe-R SR/TB 87.5mm Phenolic Insulated Plasterboard

87.5mm Unilin Safe-R SR/TB Phenolic Insulated Plasterboard combines a high-performance 75mm phenolic insulation core with glass tissue facing, bonded to 12.5mm tapered edge plasterboard using specialist adhesive. Designed for internal applications, this composite panel delivers both thermal performance and wall finishing in one step.

The 87.5mm Unilin SR/TB is engineered to provide excellent thermal insulation alongside drylining in a single installation. Ideal for new builds, extensions, and refurbishment work, this solution helps reduce energy consumption whilst creating a finished internal surface. Upgrading your home's thermal efficiency brings real benefits, from lower heating bills to enhanced comfort throughout the year.

Integral Vapor Control Layer

The composite glass tissue facing on SR/TB acts as a gas and vapor barrier, minimising condensation risk. When joints are properly sealed and taped following standard drylining practices, a complete vapor control layer is created across the wall surface.

Fire Stops

When drylining walls, fire stops must be installed at the top and bottom of each board and around all openings including doors and windows. These consist of continuous lines of adhesive that prevent fire spread behind the insulation layer. The unbroken adhesive lines also help eliminate thermal bridging, improving the overall U-Value performance of the wall assembly.

Handling, Cutting, and Storage

Unilin PIR insulation boards should be kept on a dry, level surface above ground and protected from weather exposure. Polythene wrapping alone does not provide adequate outdoor protection. Take care to protect boards during storage and on site. Always wear appropriate personal protective equipment (PPE) when handling insulation materials.
