Deluxe door frames mean quality and durability. We always emphasize long-term performance, and our systems have achieved the highest air tightness and energy ratings. The fiberglass foam-filled frame accommodates standard size steel, fiberglass and wood doors. The tough resilient fiberglass frame affords security similar to steel but will not corrode. With our state of the art technology and extensive testing, the doors will not bow, warp, crack, scratch, splinter, dent or rust as with wood or steel doors.
