A common owner project requirement (OPR) for mechanical insulation installed in the air stream, production, and/or occupant spaces is that it be free of fibers (natural or man-made synthetic).
This requirement contributes to the health of all building occupants by preventing the inhalation of airborne fibers. For high-tech clean room applications, fiber-free insulation and exposed finishes also contribute to the requirement for pristine air quality.
Aeroflex USA’s Aeroflex® brand of EPDM closed-cell elastomeric foam insulation is a fiber-free product. Aeroflex® EPDM does not contain any natural or synthetic fibers.
