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