Cascade Wood Products, Inc. expands the Frame Defense brand of lifetime warranty door frames to include Poly-Classic Frame Defense. Cascade has extruded Poly-Classic lifetime warranty window parts for over twenty years and now brings the no rot, wood like material to exterior door frame products.


This Poly-Classic material is bonded to the bottom ends of our Frame Defense products where all frames are most vulnerable, thus preventing water absorption from the bottom of the jamb which previously led to rot and decay.
