ISOterra® CGF insulation is a biosourced rigid polyisocyanurate foam board, providing exceptional thermal performance for use on residential, commercial, and industrial construction projects.

This PIR foam board has been formulated to be environmentally friendly and provide thermal resistance of over R6.4 per inch. Enerlab’s particular understanding of cold temperature performance continually outperforms and leads the way in thermal technology.

Factory coated with a fiberglass facer on both sides, ISOterra® CGF remains lightweight for easy handling and cutting. ISOterra® CGF is versatile, making it ideal for insulating interior and exterior walls, masonry cavity walls, roof decks, and other higher density applications.
