Nordik Casement Windows

Our RevoCell™ casement windows are the most energy efficient designs on the market today. The revolutionary mPVC construction yields a slimmer yet stronger frame, with more glass and natural light. Our casement windows feature triple-seal compression weather-stripping ensuring an airtight fit that prevents drafts – even during high winds. That’s why they offer triple-pane energy efficiency in a convenient dual-pane format, without the extra bulk and stress on the frame and hardware that can lead to failures. Opening outwards using a fold-away crank handle, our casement windows use top quality hardware for an easy and trouble-free operation for decades to come.

RevoCell® Casement Window Features

Convenient, easy to clean, durable and energy efficient, our RevoCell™ casement windows have been specifically designed to withstand the Canadian climate extremes.

Solid microcellular PVC insulated frames, sashes, and mullions.

RevoCell™ is designed with a revolutionary microcellular PVC structure which is superior to the hollow-chambered frame used in traditional PVC windows. This alows you to get the solidity and the performance of wood without the maintenance.

Modern exterior with up to 20% more glass than traditional PVC windows.

The strength of the RevoCell™ microcellullar PVC construction alows for leaner frames, sashes, and mullions, which in turn allows for larger glazing. Namely, 1-1/2’’ more glass on both height and width. On a double-sash window, that’s up to 20% more glazing. Isn’t that what you want from a window in the first place?

One-piece structural construction.

Most multi-paneled windows are built-in modules where each section is glued or screwed together. Our windows are engineered on one solid frame which results in a stronger, more durable window. This advanced technology results in better protection against air and water leakage. Additionally, the strength of the frame allows for a leaner design, which results in more glass and light for your window.

4-1/2” mPVC fusion welded frame.

Our 4-1/2″ deep mPVC frame is stronger and more durable than the standard 3-1/4″ frame available from most other window manufacturers. Our larger frame allows us to put the thermal pane closer to the inside of the house resulting in better thermal protection and a stronger window.

Any sash with a width of 22″ or greater comes with a standard dual arm Truth Maxim® operator which provides maximum performance to open and close larger windows with 33% less effort than other operators of its kind. These operators feature a sealable housing to reduce water and air infiltration, without the use of caulk or additional sealant.
