interior glass partitions

Our partitions are entirely designed and handmade in our workshop on the South Shore of Montreal. Our design and production process is rooted in the relationship between light and materials, and that shows in the architectural quality of every COSTAL partition. So that your partition sits perfectly in your interior, we invite you to explore the options available: colour, handles, glass type and opening system.

Custom glass partitions: our projects

Kitchen, living room, home office, bedroom: our glass partitions adapt to every room in your home.

The glass

We offer 11 types of glasses carefully selected according to current trends to create the required atmosphere and meet the desired level of privacy. Other options can also be offered upon request.

The opening

Partially divide a space with a fixed canopy or completely partition a room with our systems on hinges or pivots. Create agile interiors and benefit from all the flexibility that our sliding or accordion systems offer.

The color

Baked paint is applied to all of our windows in order to ensure their longevity. We offer a range of defined colors that can be expanded according to the needs of the project.

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.
