Our Achievements

Located in Bromont, Maison Saltbox is much more than just a residence, it is a living example of sustainability and innovation. Its design and construction were so exceptional that they were the subject of a five-part web micro-series, broadcast in the fall of 2020 by Écohabitation.


This construction in Eastman is an example of elegant architecture where the windows are perfectly integrated into the corners of the roof. This architectural harmony creates a captivating aesthetic, marrying innovation and design for a unique residential experience.

Cathy Davidson Grant

“I just wanted to tell you that we are so impressed with our windows and doors! Everyone around me is talking about them, especially the front door! That’s a world changer for passive house design! Most ppl believe it is wood till I tell them, even right up close feeling the surface. Thank you for all your patience and time with me. We are overjoyed with our choice and we have not even lived in the house yet. I’ll keep you updated!. You were an absolute pleasure to deal with in the middle of a very difficult journey.”

Marc-André Gauthier

“I recently had the pleasure of working with NZP Fenestration for my home renovation project, and I couldn’t be happier with the outcome. I opted for their Passive House windows, given the high acclaim these windows receive for energy efficiency and comfort. They truly lived up to the hype! From the onset, NZP Fenestration showcased their expertise in the premium window domain. The quality of their product is undoubtedly top-notch, and the difference in the comfort level of my home is palpable. What truly set them apart, however, was the unparalleled quality of service I received from their team.”

Isabelle Fortin

“The best windows in my life installed in an energy-efficient renovation process, the temperature of the house is stable no matter the season (in addition to improving the insulation of the house from the outside to improve airtightness). The weather is nice in the house 🥰 and we use less energy 👍, not to mention that the windows are beautiful!”
