All of our windows have the ENERGY STAR Most Efficient 2022 seal of approval, providing your home with protection from the unpredictable weather.  


Vinyl windows are nearly 100 percent scratch-free. They never have to be painted, scraped, or stained and they’re easily cleaned with soap and water. Because they’re resistant to the elements, they don’t age as fast as other windows.


Vinyl windows offer superior thermal protection. Vinyl windows keep heat in during winter and out during summer. This reduces heating and air conditioning usage for lower energy bills.


Vinyl is the least expensive of all window materials, but this doesn’t mean vinyl windows are low quality. Vinyl is durable, and it won’t rust or corrode.


All windows are backed by a transferable lifetime manufacturer warranty for as long as you own your home, giving you peace of mind in knowing you are covered if you have any issues with your windows


We offer a variety of different colors. Windows can be painted any Gentek color available that year. 


Vinyl windows not only last longer than wood and aluminum windows, but they are also recyclable—making them a very environmentally friendly window choice.


One major benefit to higher having windows with higher R-values is the amount of noise reduction they offer.

Window Styles

There's a variety of window types and styles to choose from and each has their own advantages.

Window Casing

Casings are the trim that goes around your window on the inside of the house. Although they don’t play a part in making your window more or less efficient, window casings are an integral part of creating a specific look for the windows and doors in your house. This is also an area where you can express yourself and customize to make sure you get exactly what you imagined.

In modern custom windows, casings are usually made from vinyl or wood. Because, as we mentioned, casings don’t play an integral part in the performance of your windows, the choice really comes down to what kind of look you’re trying to create inside your house.

For our windows and doors installation in Toronto and Montreal areas, we mostly use the vinyl casing for its clean look and zero maintenance. There is no right and wrong way to choose casings for your home. It really depends on what you envision the final result of your replacement project to be. The vinyl casing is generally more durable and long-lasting while wooden casing allows you to create a custom look to make sure your new windows match your home ideally.


Vinyl Casing 


Vinyl casings are an ideal solution for a modern, complete look in your home. Vinyl is a great material because it does not deteriorate or rot with time. It will also perfectly match your new vinyl windows. There are also numerous options when it comes to selecting rosettes (trim corners), that will add a unique look to your windows. Although clean and polished, most vinyl casings tend to look similar and offer little in the way of customization for a pickier customer.

Wood Casing


Because wooden casings can be stained or painted, and come in a variety of height and width profiles, they can be made to match your baseboards or another moulding in your house. The drawback with wooden casings is that they have a much shorter lifespan than their vinyl counterpart. As moisture levels change in your house during different seasons, the wood expands and contracts, meaning your casings may need to be changed long before it is time to change the window.

There are two common types of exterior finishes used in Canada:

  • aluminum cladding (capping)

  • brickmould.

Key points:​

  • Aluminum capping is used when siding and trimming custom shapes, bay and bow windows, or an older home where PVC may not work so well. 

  • Vinyl brickmould is used in full-frame replacements. Windows with vinyl brickmoulds perform better, look more modern, and have better insulation.

Aluminum Capping

The actual exterior side of the window gets covered with bent aluminum capping on the top. The bending and cutting of aluminum are done manually by the window installer.

Vinyl Brickmoulds

There are several reasons why vinyl brickmoulds are a better choice compared to aluminum capping where possible. For starters, it is all about materials. Unlike a combination of wood and aluminum, vinyl is much better at withstanding contact with moisture and the elements. Vinyl brickmoulds come in a single piece which reduces maintenance and gives moisture fewer places to get in. Aesthetically, it lends the home a richer look.



The cost of the material to trim a house with aluminum is less than buying PVC trim pieces, but the cost of installation using aluminum is higher because of the increased labor. In most cases, the total cost for either is similar.

Regardless of where your home is located, choosing windows that provide you with the highest level of comfort and energy savings year-round is extremely important. And choosing the right glass for your windows is the most important factor in the decision. Go beyond ordinary low-e glass – choose Cardinal LoĒ, the ideal choice for passive solar designs.


When the weather turns frigid, Cardinal LoĒ-180™ glass is the perfect cold remedy. It keeps homes warmer and more comfortable by blocking heat loss to the outside and letting the sun’s heat stream in. With a glass U-Factor of just 0.26 and an SHGC of 0.69, LoĒ-180 is the ideal product for passive solar applications. It extends a warm welcome home while achieving the highest ER values.


Who says you can’t do anything about the weather? Cardinal's LoĒ² coated glass delivers year-round comfort in all types of weather. In summer, it rejects the sun’s heat and damaging UV rays. In winter, it reflects heat back into the room.

When the temperature soars, ordinary window glass just can’t handle the heat. And tinted glass spoils the view. Cardinal LoĒ³-366, however, has been specially formulated to reject the sun’s heat without affecting the view. It lets more light in and keeps more heat out. So your home stays cool and comfortable. Our patented LoĒ³-366 coating provides the ultimate in performance of all our LoĒ products.

There’s no need to go to triple-pane windows to meet the various energy-saving guidelines. No need to invest in redesigning your windows and altering your manufacturing processes either. A double-pane IG unit with LoĒ-i89 can meet the guidelines.
LoĒ-i89 is sputtered onto the indoor lite, thus reflecting escaping heat back into the room and lowering U-factors. Rather than absorbing internal heat, LoĒ-i89 reflects it back into the room, making your living space feel warmer and more comfortable.
