SuperRoom®Extended Season RoomGalleryWarranty

A bright and cheerful room for any lifestyle you choose can be yours. The SuperRoom® can be a family fun room, recreational room, exercise room, game room or hot tub room. But most of all, a room where you can simply relax!

Crown's Exclusive Composite Wall Structure

Crown has separated itself from the competition with our new composite wall. We have been nationally recognized for this product innovation. The exclusive composite is a mix of wood and vinyl which gives the super room greater thermal efficiency and increased structural integrity. To enhance the beauty of the room we have also added an internal bracket system that eliminates bulky screw heads. All these attributes combined give you a strong, efficient and beautiful addition to your home.

Insulated Snap-N-Lock Roof System

Snow loads are always a concern in Michigan, but with our roof we eliminate those concerns. Crown uses a a sytem comprised of metal skins that are rolled to form a unique, patented locking system that easily snaps together, and an energy efficient continuous polystyrene foam core interface. The internal locking system eliminates the need for additional fastening methods at the joint. Sealant is encased in the joint, protecting it from ultraviolet destruction and forming a waterproof seal.

The panel adapts easily to a variety of floor plans and offers a wide range of design flexibility and usages including outdoor malls, restaurants, in-plant offices, small or large scale freestanding units, canopies, and single or multi-family homes. Available in 3”, 4”and 6” thick and up to 32’ in length.

Earthwise Vinyl Windows


Earthwise windows are manufactured in our 65,000 sq. ft. factory. The window design is built specifically for sunroom walls. They have a hefty support system allowing them to support the large spans typical in a SuperRoom®. The Earthwise window is available with the HR-4 Energy Package (which includes the “Super Spacer”, Solarban® 65 Low-E Glass, argon gas between the panes and our foam-filled frames.)

Non-Dent Vinyl Insulated Panels

Our factory manufactures all roof and wall panels used in our rooms. Vinyl panels are used as filler above, below and around the windows for strength and premium insulation. The vinyl skin gives you the benefit of a non-dent panel so you can be worry free while entertaining the children, moving furniture or mowing the lawn.


Six-Inch Poly Deck

Our poly deck consists of panels with 5” of insulation sandwiched between two 1/2” Oriented Strand Boards. Poly Decks eliminate costly foundation work and the finishing surface can be carpet, tile or almost any type of flooring.
