WoodClad windows and doors offer the best of both worlds; the durability of a fiberglass frame with the warmth of a clear, vertical-grain Douglas Fir on the interior. Milgard’s WoodClad series of windows and doors suits not only the architectural purist, but the architectural realist as well. Thanks to some ingenious engineering, WoodClad doors have no unsightly staples or nail holes that are so common in ordinary wood doors.
