RevoCell®
Our custom shaped windows feature a solid microcellular PVC construction that offers the window extra strength and insulation. This technology allows manufacturing windows that are more energy-efficient, brighter, and stronger.

More Efficient.
We build our windows for maximum indoor comfort, year-round. Our RevoCell custom shaped windows lead national charts with the highest Energy Rating (ER) with both double and triple-pane glass – in standard configuration!
Energy Rating (ER)

Stronger.
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 4½” deep frame, 38% more than the industry standard of 3¼”. This makes them more rigid and help seal the wall opening better.
As a result, our custom shaped windows achieve a whopping Performance Grade of 85, levels above the nearest competitors.

Brighter.
The extra strength of microcellular PVC allows manufacturing our custom shaped windows with slimmer frames and sashes. This adds an extra 1½” of glass in each dimension compared to ordinary PVC windows. Our internal mullions are only 4½” 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?

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 looks have 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.

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

Rectangular
This classic divided-lite look offers a traditional Old-World aesthetic. Works equally well on traditional and newer homes, adding a timeless elegance.

Partial Covering
Our grilles can be aplied to a portion of the window only. Combined with an SDL profile, you can also reproduce a hung sash appearance on a casement window.

Contour
Contour grilles go around the perimeter of the sash. Often associated with the Prairie School style, they add a artsy touch that’s distinctively North American.

Diamond Patterned
The diamond pattern can add an artistic touch to a traditional home. The understated charm of thin grilles adds extra interest from up close.

Divided Lites
Our grilles can be aplied to a portion of the window only. Combined with an SDL profile, you can also reproduce a hung sash appearance on a casement window.
Speciality Glass
We also offer some alternatives to clear glass in your windows. Tinted glass can be used to lower light levels, or to alter the colour balance indoors. Textured glass adds a degree of privacy as well as decorative interest, while letting natural light inside.
