Who we are

An Innovative
Canadian Company

Accurate Dorwin has been providing general contractors, custom home builders and discerning homeowners with the highest quality fiberglass windows and doors since we first pioneered them in 1983. Our quality and exact fit-n-finish details sets us apart.

While we pride ourselves in our ability to exceed the needs of both commercial and residential customers across Canada and the US. Are products being ideal for Net Zero projects and are Passive House ready due to our use of low conductivity materials and triple pane glass selection.

From new builds to historical buildings, we bring quality and experience to the table, so keep your standards high, and trust Accurate Dorwin windows and doors to stand the test of time in your building.

High Performance Is Our Minimum Standard

Whether we’re talking about windows and doors or our talented team, high performance is Accurate Dorwin’s bare minimum. Our total team approach has our experienced account managers, estimators, project managers and our production and logistics group joining together to ensure a more personalized experience from start to finish.


Pultruded Fiberglass window frames combined with high efficiency insulating glass can help reduce the world’s energy consumption. Fiberglass is made from silica sand — an abundant natural resource, so there is less embodied energy in fiberglass as compared to PVC, aluminum, and wood, which require gas and petrol-chemicals, electricity, and slow growing trees to make, respectively.

Accurate Dorwin is a certified LEED (Leadership in Energy and Environmental Design) company.

LEED is an internationally recognized third party green building certification system that encourages and accelerates the adaptation of sustainable green building practices. When you’re designing a space and specify Accurate Dorwin FIberglass windows, you can earn LEED points in the following key areas:

Energy Efficiency

Indoor Environmental Quality

Material Selection

Pultruded fiberglass is our material of choice for windows, meaning they have a much lower thermal conductivity than other materials. This combined with our insulated frames and sashes, results in some of the most energy efficient windows in the world.
