Frame Construction

  • Head, seat and side jambs are constructed of 1-1/4” furniture-grade hardwood oak veneer.
  • The finest hand-selected veneer in the industry provides a frame that is 67% thicker and stronger than those used by many window companies.
  • Frames are assembled utilizing 5” hardened steel screws, rather than the “stapled” construction that is common in the industry.


Competition’s ¾” Shop-Grade Veneer


Castle’s 1¼” Furniture-Grade Veneer


  • Deluxe Super-Seat features a unique layered design combining 1” high-density polyisocyanurate (Dow Tuff R)
    insulator board and 3/4” exterior-grade plywood exterior surface.
  • Deluxe insulated seats are 3 inches thick and provide a superior R9 insulating value.

Heavy-duty PVC exterior and interior mullion profiles snap into place and are reinforced using threaded steel rods and high-density polyurethane foam.
