What is the price difference between vinyl and fiberglass windows in Ottawa?

Vinyl windows typically cost $100-300 less per window than fiberglass in the Ottawa market. You can expect to pay $400-800 for quality vinyl windows installed, while comparable fiberglass windows run $600-1,100 per window.

The price difference comes down to material costs and manufacturing complexity. Vinyl windows are mass-produced using PVC extrusion, making them the most budget-friendly option for Ottawa homeowners. They offer excellent energy efficiency with double or triple-pane glass and perform well in our climate zone. Most vinyl windows come with fusion-welded corners and multi-chamber frames for insulation.

Fiberglass windows cost more because the material is more expensive to produce and requires more specialized manufacturing. However, they offer superior durability and dimensional stability compared to vinyl. Fiberglass expands and contracts at nearly the same rate as glass, reducing seal stress over Ottawa's temperature swings from -30°C to +35°C. They also maintain their appearance longer and can be painted if you want to change colors.

For a typical Ottawa home replacing 12-15 windows, choosing vinyl over fiberglass could save you $2,000-4,000 on your project. Both materials qualify for the Canada Greener Homes Grant (up to $5,000) and Enbridge rebates when you choose ENERGY STAR certified models with U-factors of 1.22 or lower.

The best choice depends on your budget and long-term plans. Vinyl offers excellent value for most homeowners, while fiberglass provides premium durability if you're planning to stay in your home long-term.
