What We Do

Fiberglass Windows

Fiberglass is a material created by saturating micro strands of glass fiber with resins, making it strong and durable enough that it’s found in modern aircraft design, turbine windmills, and even bridges.

Fiberglass profiles are carefully engineered so the fiber strands create some of the strongest window framing material on the market. The incredible strength results in thinner frames, which maximizes glass surface and provides spectacular views.

Window buyers in North America— whether residential or commercial— choose fiberglass for strength, stability, energy efficiency, durability, and to limit their environmental footprint.

Accurate Dorwin prides itself in using pultruded fiberglass, allowing us to provide an added layer of quality to our customers. Virtually impervious to moisture, our windows won’t bend, warp, discolour, corrode, rust, fade or deteriorate no matter what Mother Nature throws their way. In fact, Accurate Dorwin fiberglass windows are 8 times stronger than PVC — the material commonly found in our competitors’ products. 

Because the entire window is made from the same material – glass – there is a consistent and unified expansion and contraction that happens with changing weather. This means that unlike other materials like wood or PVC, there is a very low risk of Accurate’s fiberglass windows experiencing seal failure, glass breakage, or frame stress.

Our quality installation, superior materials and selection make Accurate Dorwin the best choice for your new doors.

While traditional window framing materials are dimensionally stable on the shop floor, how they perform in the real world during extremes of humidity, heat, and cold is quite a different story. With metal-clad wood, PVC, and aluminum frames, the varying expansion rates between the glass and frame can result in stressed frames, air leakage, broken glazing seals, condensation, and inoperable hardware. With fiberglass, the window glass and frame materials are the same, allowing the glass and frame to expand and contract at the virtually same rate.

Curtain Walls

Curtain walls can span multiple stories, or be leveraged for a single floor.
A curtain wall system is an outer layer of a building that is non-structural,
meaning it’s utilized solely to keep the weather out and the occupants in, in a
cost-effective, design-forward way.

Residential Fiberglass

Being a Canadian company, we know harsh, unpredictable weather takes a toll on windows and doors, which is why Accurate Dorwin solely works with the strongest material out there — fiberglass.

Fiberglass is such a strong and durable material, that it’s actually found in modern aircraft design, turbine windmills, and even bridges.

Being as strong as it is, it can hold up without bulky frames, meaning you get more glass surface and maximized views.
Strength aside, homeowners in North America choose fiberglass for its durability, energy efficiency, and subsequently, to limit their environmental footprint.

They are virtually impervious to moisture, so they won’t bend, warp, discolour, corrode, rust, fade or deteriorate no matter what Mother Nature throws their way.

Fiberglass allows for a consistent and unified expansion and contraction that happens with changing weather, so unlike wood or PVC, there is a very low risk of our windows experiencing seal failure, glass breakage, or frame stress.

Accurate Dorwin’s fiberglass windows are 8x stronger than PVC — the material commonly found in our competitors’ products.

High quality, beautiful windows and doors can make a significant difference when it comes to your home’s curb appeal. Take a look at our gallery of before and after photos to see for yourself!
