Our mission is to make windows that are exceptional in appearance, security, and strength.

Our fields of expertise range from construction management to architecture, issued from the merging of two companies: Qualum International and Ovvio Architectural.

Together Qualum International and Ovvio Architectural create windows for your project that provide a unique level of aesthetics, comfort and security with energy efficiency, durability, easy maintenance.

This combination of knowledge and experience sets us apart and we work with all clients in developing every detail of their project from design, through the structural requirements, to installation.

Our strength makes us competitive in offering superior quality windows in a variety of collections and customization options and allows us the ability to bid on projects of all sizes: residential, commercial, or institutional.


Based in Rawdon, Quebec, Ovvio Architectural is a leader in window manufacturing, sustained by production and engineering teams with over 25 years of experience and a history of partnership with some the biggest aluminum companies in North America.


Established over 60 years ago, Qualum, formerly a division of Alsco, Alcan and Genteck, specializes in manufacturing aluminum windows and related products. Recently acquired by Ovvio Architectural and renamed Qualum International, the company has been relocated in Montreal, Quebec and will continue to provide quality aluminum windows and develop new products and technologies.

Together our companies offer you years of experience, combined strengths, and innovative production technologies.
