Based in North Vancouver, Unison has been in the window and door business since 1978.

Unison treats our customers with consideration and care. We listen and take the time to explain why our products are considered to be one of Pacific Northwest’s best window and door manufacturer because we understand that making the right decision can be an overwhelming process.
Our company has built a strong relationship with the respected Wood Science Department at the University of British Columbia and Germany’s Rosenheim Wood Technology Department, providing us access to world-class wood products research and development, resources and expertise. We utilized this relationship when we required a method for gluing the onerous wood species, Ipe, to more common woods such as Douglas Fir. This was an accomplishment that was previously not possible in our industry.
Unison doesn’t limit its innovation to materials; we have developed distinct product designs that include: Hybrid Curtain Wall and Outswing Tilt and Turn Casement Window, which exceeds traditional window design and performance.
By investing in research and development, Unison has been able to develop products that break the stereotypes of wood fenestration products. By following high quality processes and procedures, our wood products can last a lifetime without maintenance. As a result of these high standards we are able to offer one of the best warranties in the industry.
Environmental mission and strategy (ESG)
Unison Windows and Doors selects only the finest material from forest certified suppliers ensuring products originated from sustainably managed forests. To further our commitment to sustainable living, our products exceed the BC Energy Efficiency Act requirements.
Wood is the most sustainable material that can be used for windows and doors: it is renewable, it stores carbon dioxide, it can last a lifetime if properly maintained, and any waste generated doesn’t harm the environment.
In addition to using the most sustainable material, we are a progressive company open to integrated design – we prefer to offer our knowledge early on in a project to minimize mistakes, waste, and cost.
Unison was featured in Western Living (Jan-Feb, 2010), as a prominent component in Allan Peters’ energy-efficient design of a West Vancouver residence. Our latest glazing and “Low-E coating technology” applied to the windows and doors combined with incorporating their use of natural materials provided an essential element for the homes’ sustainable design.
