Nana Wall



After 30 years in business, Nana Wall has become the most-trusted supplier of window walls for architects, builders, designers and homeowners, with over 20 different unique systems available. Nana Walls transcend the physical hardware from which they are built– glass, metal, and plastic – to offer something truly unique; the ability to bring the outdoors inside, allowing owners to enjoy a seamless transition between outdoor escape and indoor comfort. For people living in a harsh climate like Toronto, maximizing the enjoyment from each and every warm (or warmish) day is vital to getting the most out of our all-too-short GTA summers.

Nana Wall pioneered the category of operable glass wall systems. If you want the real thing, and not just a generic copy, there is only one authentic Nana Wall – a name that continues to lead the market in performance, beauty, and durability.

Nana Wall systems come in a selection of products for both residential and commercial application. With over 50 standard colours they are sure to fit your home. From frameless all glass systems to all wood doors you can customize your opening. There are also many configurations and stacking options to ensure it will with your home.

It was a pleasure dealing with Gem Windows right from the start. The salesman was pleasant and helpful and the installer was professional and courteous. Very happy and I’ve already recommended Gem Windows to my friends and family!

At GEM Windows & Doors, we don’t have the big box store doors; we have high quality, sturdy doors. Our 2-1/4” frame doors give that extra stability that those other doors can not provide. Our models include Colonial, Victoria and full glass to match your front door and home.

With the self-storing screen, you can have a glass only view while your screen is tucked away. When you need to let in some air, do so with confidence and unobstructed views.
