Koch & Co. Doors

koch1 koch2 koch3

Koch & Company patented designer door has taken the best of both worlds and put it into one: first, taking the wood off the exterior and using a durable clad to face the elements of weather; second, leaving real wood on the interior of the home where the beauty and warmth belong, without the problems of a real wood exterior. Finally, the Formanek door insulates a home for energy savings.


Koch & Co., Inc. has a genuine real wood, quality hand-crafted in the USA, interior that comes in oak, maple, cherry, fir,pine, k-pine, alder, k-alder, hickory, and mahogany and requires no special finish or finishing technique. The clad exterior has the strength of steel and is durable and secure, without splitting or being damaged by weather. Painting the exterior is simple, quick, and requires little maintenance. The insulated core is energy efficient and helps to reduce energy loss.


A 10 year (limited) manufacturer's warranty is offered on all Koch & Co. Doors
