Product Application

Pitched roof insulating board

Kingspans premium performance lower-lambda value phenolic foam board, Kooltherm K107, is suitable for use in above, between or below rafter level applications as well as dwarf walls and loft floors.

Product Make-up

Core: Kingspan Kooltherm K107 Pitched Roof Board is a premium performance fibre-free rigid thermoset phenolic insulant.

Facings: Faced on both sides with a low emissivity composite foil, autohesively bonded to the insulation core during manufacture. This reflective, low emissivity surface improves the thermal resistance of any unventilated cavity adjacent to the board.
