Johns Manville Exact-O-Mat® and Exact-O-Board® are manufactured using flame-attenuated borosilicate glass fibers bonded with a thermosetting resin. Both products are manufactured to extremely close thickness tolerances suitable for applications with limited-space and where restriction of air-flow is critical.
Exact-O-Mat is a flexible, resilient, blanket-type fiber glass insulation faced on one side with a smooth, durable, nonwoven, treated mat designed for HVAC equipment applications. It is also suitable for other equipment applications that require effective thermal and acoustical control, low air friction and excellent damage resistance.
Exact-O-Board is a rugged, board-type fiber glass insulation designed for use in air conditioning units and other air handling equipment applications. It is also suitable for other equipment applications that require strength and durability, high thermal and acoustical values and excellent space adaptability.
