FUSION-WELDED STRENGTH
Great Lakes vinyl replacement windows are designed and manufactured to be the strongest replacement windows you can find - and they're guaranteed to last a lifetime. Unlike ordinary windows with screwed or stapled corners that weaken and come loose with time, every sash of the Great Lakes window is fusion-welded to ensure an airtight seal. This means a stronger, better insulated corner that won't let air or water penetrate.

Great Lakes offers all popular window styles: Double-Hung, Bay, Bow, Casement, Awning and Slider, as well as Sliding and Hinged Patio Doors.

GUARANTEED FOR LIFE
Great Lakes Window believes so strongly in the durability of its products, it offers a Lifetime-Plus Warranty on the entire window. That means your windows are protected under warranty for as long as you live in your home. The "Plus" means your warranty is transferable to a second property owner if you move - protecting and increasing the resale value of your home.

SPECIALTY SHAPES & FINISHES
Specialty shaped windows allow you endless design options. At Great Lakes, our specialty shapes and sizes are limited only by your imagination. A variety of colors are available including White, Camel, Earthtone, Golden Oak, Natural Oak & Colonial Cherry interior finished to give you the look you want.

Colonial grids, diamond grids, beveled-leaded glass, or Regal v-groove hand-cut glass options are also available to customize your windows.

Low maintenance Easy-Clean™ Glass is also available on all Great Lakes Windows. Easy-Clean Glass works the same on glass as Teflon does on cookware. It is a higher quality of window glass that protects it from contaminants and drastically reduces the need and difficulty of repeated cleaning. In fact, Easy-Clean glass requires washing half as often as ordinary glass.

With the Great Lakes advanced 7-point locking system, home security has taken a giant step forward. The seven separate concealed locks are all activated simultaneously by one solid brass sculptured handle.
The result: the most secure patio door available today.

Sliding patio doors are also available. Choose from White, Camel, Earthtone, Golden Oak, Natural Oak and Colonial Cherry finishes to complement and enhance your home.
