Exact-O-Board® is made from strong, flame-attenuated borosilicate glass fibers bonded with a thermosetting resin. Exact-O-Board liners are formed to close thickness tolerances with smooth uniform surfaces. Their porosity and inherent structure results in highly effective thermal and acoustical control in a minimum amount of space.


Exact-O-Board® is a rugged, board-type fiber glass insulation specifically designed for use in air conditioning units and other air handling equipment applications. It is also suitable for other equipment applications requiring strength and durability, high thermal and acoustical values, space adaptability, and attractive appearance.
