Unison Windows and Doors’ core business is built on working with clear, vertical-grain Douglas Fir, from BC’s Pacific Northwest, and has expanded to incorporate a variety of prestigious wood species. We select only the finest material from forest certified suppliers ensuring that each Unison product originates from sustainably managed forests.

Our projects have featured wood species such as: Black Walnut, Mahogany, Teak, Ipe, Alder, Cherry, White Oak, Pine and Yellow Cedar. Windows & door components are typically milled from one solid piece. We also offer the option of laminating exotic hardwoods over solid block-board cores to provide environmentally friendly and high performing components.
