Our History

Altex was founded in 1975 in Ville Saint-Laurent by Michel Alepins and his sons, Paul and Gaetan. We specialize in custom window treatments for the residential, commercial and architectural sectors. In 1989, Altex moved to Terrebonne to increase its productivity and better meet the growing demand for our products. In 2012, our family business also acquired SunProjectTM, a Toronto-based company that specializes in light and energy management.

Constantly evolving and innovating, Altex sells its products throughout North America and partners with companies around the world to provide the highest quality in fabrics, mechanisms and control systems, many of which are patented.

Altex is proudly rooted in Canada.

“From the time he founded his first business in 1913, our grandfather was always committed to offering his customers the very best service. My sons and I are so proud to carry on this entrepreneurial legacy that started over 100 years ago! And the reason we’ve lasted is because we’ve never lost sight of our main focus: keeping our customers happy.”

Gaetan Alepins, President of Altex®
