Our standard exterior wood doors are 1 3/4” thick, with insulated glass and extra thick “Energy Guard” panels in most models. We stock our exterior doors with wider stiles so that a broader spectrum of hardware will fit, and to improve sturdiness of the lock area. We work with manufacturers so that the doors we carry are built with the best technology available to ensure maximum strength and resistance to the elements. Custom exterior doors can be built up to 4 feet wide, 10 feet tall, and 2 1/4” thick in almost any wood.
