RAFTERLOC

Variable Width Pitched Roof Board

Unilin Insulation’s Rafterloc Pitched Roof insulation has a unique width variation feature offering a 20-30mm adjustment margin to ensure a tight fitting, high performance insulation locked between rafters.

Used in conjunction with a layer of Unilin XT/TL or XT/PR_UF below the Rafterloc system provides a robust, cost effective solution to insulating sloped rafters to the most efficient standards with minimal wastage and reduce fitting time.

The improvement in energy efficiency standards required by the recent revision of Building Regulations in Ireland has demanded better insulation U-Values to be achieved with better detailing to ensure improved performance.
