Comfort Smart Patio Doors for Michigan Homeowners

Save on energy costs.

Patio doors make it easy to connect your indoor and outdoor living spaces and can be configured to meet ENERGY STAR® performance requirements for Version 6.0 to keep the elements outside. We also combine a sturdy fusion-welded frame, reinforcement in operating and fixed sashes, heavy-duty weatherstripping and full one-inch thick insulated glass to create a tight, energy efficient sliding patio door.

Open your door to color.

We offer a full spectrum of interior and exterior colors to complement your siding and trim. Choose from our standard palette of solid vinyl colors or new heat-reflective paint in dark colors. On the interior, choose from neutral colors to coordinate with painted trim or you can add woodgrains, an attractive option on select product lines.

Distinctive glass design.

Our glass designs offer an elegant passage to the outdoors. From distinctive to dramatic, the style you choose will bring out the best in your home’s personality. Even better, our decorative grilles can be placed within the insulated glass unit, making them easy to clean. Or select simulated divided lite grilles, which are on the outside of the glass for a more traditional look.

Seamlessly safe and secure.

For greater protection against forced entry, our patio doors lock along the jamb at the three most critical points. Locks and handles come standard in White, Beige and Bronze, with an option to upgrade to an elegantly finished handle or keyed lock in White, Beige, Bronze, Satin Nickel or Brass. Want to match your décor inside and out? Select our two-tone option to color coordinate your interior and exterior patio door handlesets.
