Our window frames, sashes, mullions, and brickmoulds are solid inside, which makes then stronger than the typical hollow chambers used in PVC replacement windows. All of our windows come standard with a 4.5” deep frame, 38% more than the industry standard of 3.25”. This makes them more rigid and help seal the wall opening better.

As a result, our casement windows achieve a whopping Performance Grade of 85, levels above the nearest competitors.

The extra strength of microcellular PVC allows manufacturing our casement windows with slimmer frames and sashes. This adds an extra 1.5” of glass in each dimension compared to ordinary PVC windows. Our internal mullions are only 4.5” wide, as opposed to the usual 6-7”. And our glass is clearer. As a result, you get more glass, and more natural light inside your home.

Isn’t that what you put windows in your wall for?

Take a look at this gallery to see what our Casement windows can look like installed in a home.

Custom Is The New Norm

Gone are the days when window companies dictated what your home should look like. Every single window we build is as unique as you want it. From factory finishes to custom paint, decorative grilles or simulated divided lites, textured or tinted glass, the combinations available are virtually endless.

Add some colour

Most homeowners get their replacement windows in stock white, which is a great all-around colour. But you don’t have to: our comprehensive palette of exterior factory finishes will match any home style and help elevate its look.

Standard colours

Our windows’ interior colour is white, but exterior colours are also available in several affordable factory finishes. Our standard colours are engineered in cap stock (coloured PVC) for lighter tones and durable, architectural-grade laminate for the darker tones. They are extremely colourfast and and more durable than paint. We also offer a full-black (exterior and exterior) on select windows. Please contact us to inquire about the availability of custom-painted colours.

RevoCell Casement, Awning, and Bay mPVC windows are offered in a variety of colours.

Grilles Patterns and Styles

In the old days, large panes of glass could not be manufactured cost-efficiently, so windows were filled with many smaller pieces of glass held in the sash by bars called muntins. These divided lite look has become a sought-after architectural element, especially on traditional home styles. Take advantage of our window customization expertise to elevate the look of your new windows

Internal grilles are installed between the panes of glass, inside the the insulated glass unit. This allows for the easiest window cleaning. Our internal grilles are available in a variety of profiles, sizes, and finishes.

An example of a diamond patterned grille in a Nordik Window.

Simulated divided lites (SDL) are external grilles. They are applied on the exterior of the insulated glass unit and give a more realistic muntin appearance. Like internal grilles, our SDL’s are available in multiple profiles and finishes.

Grille Patterns

We offer a variety of patterns for window grilles. Here are a few of the most popular ones. You can mix and match internal and external grilles to get the exact style your require.
