Highly efficient windows

At our facility, we have our own weather testing lab. We ensure that our products respond to the realities of our harsh Quebec climate. We also manufacture our windows with 3 black or grey weatherstrips to avoid discolouration, which are placed on the shutter to offer maximal airtightness.

Customizable options

Whether they are casement, contemporary or colonial, sliding, architectural or awning windows, you are sure to find the best windows to showcase your home. We have so many options! Our advisors and our window selection tool will help you choose the model that best suits your project.
