RevoCell® Custom Shaped Window Features

Fixed windows can be custom-shaped in virtually any form, from arches to sharp corners; if it can be designed, we’ll build it! Architectural windows are great for transoms, sidelites, or together with venting units in bay, bow, or other configurations. With our microcellular PVC frame, they offer a coordinated sightline with our casement and awning windows. With a weather-tight but bright construction and great insulation, our fixed windows are rated Energy Star Most Efficient.

Custom Shaped Windows - Microcellular PVC Construction

Microcellular PVC Construction

Our RevoCell® window frames, brickmoulds, and sashes are insulated with billions of closed microscopic cells for superior energy efficiency. They are fusion-welded as a single unit, impervious to the elements. The microcellular PVC structure has better screw holding power for hardware, and distributes stress better than hollow window frames, for extra durability.

Custom Shaped Windows - Contemporary Design

Contemporary Design

Our RevoCell® custom shaped windows feature a minimalist, slim profile that goes equally well with traditional and contemporary home designs.

Custom Shaped Windows - 4½” Fusion-welded Frame

4½” Fusion-welded Frame

Our custom shaped windows come standard on a 4-1/2” deep frame, which is stronger and more durable than the standard 3-1/4” sold elsewhere. The deeper frames give extra dimensional stability and strength. It also allows for a lower sash profiles to maximize the glass surface.

Custom Shaped Windows - Structural Construction

Structural Construction

Our RevoCell® multi-lite custom shaped windows feature structurally strong, seamless one-piece frames with integrated cross-mullions, as opposed to the more common modular construction where each lite is a separate window. Our single frame will transfer loads better through the wall, will deflect stronger winds, and have fewer points at risk of water ingress or air leaks. It will also allow for a larger glass surface for more natural light.

Custom Shaped Windows - Dual and Triple-pane Insulated Glass Units

Dual and Triple-pane Insulated Glass Units

Two or more layers of glass are joined together to create sealed hollow chambers that act as a thermal buffer. This drastically reduces direct heat transfer through the glass, as well as helps prevent condensation and ice build-up. It also helps soundproof the interior, especially in conjunction with a high-quality cellular spacer.

Custom Shaped Windows - Low-emissivity Coated Glass

Low-emissivity Coated Glass

An invisibly thin coating is applied onto one or more of the glass surfaces, reflecting most of the heat in the form of infrared radiation back inside the home during winter and outside during summer, while letting most visible light pass through.

Custom Shaped Windows - Argon Gas Filling

Argon Gas Filling

The air between the glass panes inside a thermal glass unit is replaced with argon. This inert, odourless gas is heavier than air, reducing convection between the panes. Its lower specific heat capacity reduces direct heat transfer. The argon fill hence reduces heat loss, and offsets water vapour to prevent condensation between the panes.

Custom Shaped Windows - Ener-Edge® Warm-edge Spacer

Ener-Edge® Warm-edge Spacer

Our insulated glass units use a cellular silicone warm-edge spacer with the lowest thermal conductivity on the market, minimizing heat transfer between the interior and the exterior. It also allows for the natural expansion and compression of glass due to environmental temperature changes without failing the seal between them.

Custom Shaped Windows - Triple Weatherstripping

Triple Weatherstripping

Our RevoCell® window sashes use three continuous seals at the interface with the window frame and mullions. This stops drafts and the associated heat leaks through the window. The thermal glass unit is also sealed to the sash from both the inside and the outside.

Custom Shaped Windows - PVC-cladded Interior Wood Extension

PVC-cladded Interior Wood Extension

Our custom shaped windows use an interior wood extension that can be manufactured in any depth. This extension is cladded with maintenance-free PVC, providing a finish that does not need sealing or painting. It also allows for the installation of blinds or other window treatments, and adds to the window strength and durability.

Custom Shaped Windows - High-gloss Finish

High-gloss Finish

We use the highest-grade PVC powder and fabrication techniques which result in a high-gloss PVC finish. As a result, our custom shaped windows are easier to clean, more durable, and won’t fade or yellow over time.

Custom Shaped Windows - Integrated Brickmould Option

Integrated Brickmould Option

A brickmould that is part of the window frame creates a superior window assembly. The microcellular PVC construction adds insulation and window strength. It also means less chance of water and air leakage.

Custom Shaped Windows - Durable Standard Colours

Durable Standard Colours

Our RevoCell® windows come in several standard colours that are engineered during the profile extrusion. Lighter tones are made with cap stock, meaning a layer of tinted PVC covering all exterior-facing surfaces. The darker tones are architectural-grade laminates that are UV reflective and extremely colourfast. Our standard colours are extremely UV and weather-resistant, and won’t peel, flake, or scratch like paint finishes.
