R-FACTOR - Fiber Mat

BGF’s new R-FACTOR is a breakthrough, award-winning innovation for high temperature insulation that provides consistent, reliable product uniformity and performance surpassing any comparable product on the market today.

R-FACTOR is a process that produces an unprecedented 4.5pcf density mat with physical characteristics that are exceptionally uniform and consistent. A variety of fibers can be used to develop an R-FACTOR mat, such as fiberglass, SilcoSoft®, and other high-performance fibers.

R-FACTOR is an adhesive-free, mechanically bonded mat weighing in at only 4.5 pcf with thicknesses ranging from 0.75 to 1. Proprietary processing methods allow for flexibility of the high-temperature fibers utilized. R-FACTOR is particularly effective where low weight and low density are key design parameters. R-FACTOR also offers excellent thermal and acoustical performance in high-temperature environments.

Partner with BGF to develop a customized solution with R-FACTOR that will meet and exceed the requirements of your engineering design project.
