Product Application

Timber and steel frame insulating board

Kingspans premium performance lower-lambda value phenolic foam board, Kooltherm K112, is suitable for use in timber and steel frame wall lining applications.

Product Make-up

Core: The core of Kingspan Kooltherm K112 Framing Board is a premium performance rigid thermoset modified resin 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.
