indoor glass partitions

Our windows are entirely designed and handmade in our workshop on the south shore of Montreal.

Our design and production process is deeply linked to the importance of the relationship between light and materials, which is reflected in the architectural quality of our Costal divisions.

To make your canopy fit perfectly into your home, we suggest that you explore the possibilities in terms of color, handles, type of glass and types of openings available.

Our added value

COSTAL divisions give interior environments a refined presence and an exceptional atmosphere. Both robust and minimalist in design, the glass and profiled steel structure integrates advantageously into spaces where abundant natural light circulates.
