Exact-O-Board Rugged Fiberglass Board Insulation for Applications Focusing on Reducing Thermal Transfers and Reducing Sound Transmissions

Fiberglass insulation is the most widely used insulation because of its excellent thermal and acoustical properties. As a Select Master Fabricator for Johns Manville, Pacor has access to the broadest line of industrial fiberglass insulation products in the industry. Exact-O-Board® can be bought as boards or can be cut into a variety of customer specified parts. Contact a Pacor insulation specialist today to find out if Exact-O-Board ® is the solution to your fiberglass insulation needs.


Exact-O-Board® is a rugged type of fiberglass board faced on one side with a smooth, durable, non-woven, treated mat. This fiberglass insulation provides high acoustical values in the high and low frequency ranges normally encountered in air handling equipment. It is ideal for use in equipment applications requiring strength and durability, high thermal and acoustical values, space adaptability and attractive appearance.


Exact-O-Board® is well-suited for use in air conditioners, furnaces and HVAC equipment in an effort to reduce thermal transfer and reduce sound transmission. This fiberglass insulation can be manufactured to extremely close thickness tolerances so it is ideal for applications in which the restriction of air flow is critical.

This strong resilient fiberglass board insulation resists damage and withstands the effects of high air velocities. It is available as thin as ¼″ (6mm) for limited space applications.


Exact-O-Board® fiberglass boards are formed to close thickness tolerance with smooth uniform surfaces. Their porosity and inherent structure results in a highly effective thermal and acoustical control in a minimum space.

This product is best equipped for smooth surfaces requiring excellent performance with regards to resistance to high velocity and limited thickness tolerances. The standard product is furnished in black with a choice of thicknesses and densities.
