Superior Performance PIR Insulation

XO/FB

Applications: Wall / Framing

XO/FB

XO/FB is designed for use in a wide range of construction including steel or timber frame applications up to 18m in height. The framing board can be used between studs or as an insulated sheathing board.

Using XO/FB in this application will reduce the thermal bridging of the steel or timber studs.
