Fire Rated Frames
Fire-Rated Wood Door Frames

Fire Rated Frames are Ferche Millwork’s complete line of fire rated wood door frames certified by Intertek Testing, formerly known as Warnock Hersey, Inc. (WHI). These solid wood and wood veneered firerated door jambs are certified with 20 minute, 45 minute, 60 minute and 90 minute ratings. They are available in most any wood species. These wood, rated door frames are the perfect hollow metal replacement frame for architects and designers to select when a rated jamb is needed and the beauty of real wood is desired. Condominium fire rated door jambs, high end commercial rated door frames and fire-rated garage door entry frames in single family homes are examples of great applications. The FireRatedFrames jambs are the perfect solution to meet fire protection requirements without the institutional look of metal frames.
