What is the difference between double and triple-pane windows?

Double-pane windows have two glass layers and one insulating gas chamber; triple-pane windows add a third layer and a second chamber, which significantly reduces winter heat loss and outside noise. For Ontario's climate, triple-pane delivers the best comfort and energy savings, while double-pane is a strong, cost-effective option for sheltered or interior exposures.

Should I choose a steel or fiberglass door?

Steel entry doors offer excellent security and a clean, bold look at a lower price point, while fiberglass doors match that security with better insulation, higher dent resistance, and realistic wood-grain finishes that won't warp or rot. Both are excellent — we'll help you choose the right fit for your home's security needs, style, and budget.

What areas do you serve?

Trust Build is headquartered in Concord with locations in Grimsby, East Gwillimbury, and Barrie, serving Toronto, Vaughan, Mississauga, Markham, Oakville, Burlington, Richmond Hill, and communities across the GTA and Ontario.

How long does a window or door installation take?

Most single-window or single-door installations are completed in a day, and full-home window replacements typically take one to three days depending on the number of openings and any masonry or trim work involved. We confirm the exact timeline in your written quote so there are no surprises.

Can I get a rebate on new windows, doors, or attic insulation?

You may qualify for the Home Renovation Savings™ program — up to $100 per rough opening for ENERGY STAR® certified windows and doors (a home energy assessment is required before work begins), and up to $1,250 for standalone attic insulation or up to $1,500 when bundled. Our team will confirm how it applies to your home. Full details at homerenovationsavings.ca.

Know Before You Buy

Not Sure Which Product Is Right For You?

Choosing between double and triple-pane windows — or steel versus fiberglass doors — is one of the most common questions Ontario homeowners face. Here's what actually matters.

Double-Pane vs Triple-Pane Windows

Feature	Double-Pane	Triple-Pane
Glass Layers	2	3
Insulation (R-Value)	Good	Excellent
Noise Reduction	Moderate	Superior
Best For	Mild climates, budgets	Ontario winters, comfort
Energy Savings	✓	✓✓

Triple-pane windows are the gold standard for Ontario homes. With an additional glass layer and two insulating gas chambers, they dramatically reduce heat loss in winter and keep cooling costs down in summer. Double-pane remains a solid, cost-effective upgrade from single-pane — especially for interior or sheltered exposures.

For Ontario's climate, triple-pane is the standard we recommend for maximum comfort and energy savings.

Full double vs. triple-pane comparison

Steel Doors vs Fiberglass Doors

Feature	Steel Doors	Fiberglass Doors
Strength & Security	Excellent	Very Good
Dent Resistance	Moderate	High
Insulation Value	Good	Excellent
Maintenance	Low	Very Low
Appearance	Classic, bold	Wood-grain or smooth options
Best For	Security-focused homes	All-round performance

Steel doors offer outstanding security and a clean, modern look at a lower price point. Fiberglass doors match that security level while adding superior insulation, better dent resistance, and the ability to mimic the warmth of real wood grain — with none of the warping or rotting.

Both are excellent choices, and we'll help you select the right fit for your home, security needs, and budget.

Engineered For Ontario

Triple-Pane Glass Unit

Ontario winters are unforgiving, so we supply window systems selected to perform in this climate. Our triple-pane glass option uses three panes of glass, two insulating chambers, and the cold-climate engineering that keeps your home warm in January and comfortable in July.

Triple-Pane Construction

Three layers of glass with two sealed chambers dramatically slow heat loss compared to standard double-pane.

Argon Gas Fill

Each chamber is filled with argon — a dense, non-toxic insulating gas that resists heat transfer far better than air.

Dual Low-E Coating

Microscopic coatings reflect indoor heat back inside during winter and deflect solar heat in summer.

Super Spacer®

We use Super Spacer® — a premium, foam-based warm edge spacer system from Edgetech, trusted in high-performance residential and commercial glazing worldwide and tested to the highest industry standards. By replacing the conventional metal spacer at the edge of the glass, Super Spacer® minimizes the cold bridge where heat is most easily lost — reducing condensation, improving the overall energy efficiency of the sealed unit, and helping your windows perform better through Ontario's coldest months.

The result can be fewer drafts and better year-round comfort. ENERGY STAR® certified options are available and installed by our own crews. Double-pane configurations are available where triple-pane isn't required.

Ontario Rebates

You May Qualify for the Home Renovation Savings™ Program

The Home Renovation Savings™ program — administered by Enbridge Gas and Save on Energy (IESO) — helps eligible Ontario homeowners offset the cost of energy-efficient upgrades. Two of the upgrades we install most often may qualify, and we can pair your rebate with 0% financing for 12 months through Financeit.

ENERGY STAR® Windows & Doors

You may receive up to $100 per rough opening when you upgrade to ENERGY STAR® certified windows or doors. A home energy assessment is required before any work begins, and rebates apply when you bundle eligible upgrades (for example, a minimum of three window rough openings, or one qualifying door, skylight, or sliding door).

Attic Blown-In Insulation

You may receive up to $1,250 for standalone attic blown-in insulation with no assessment required, or up to $1,500 when bundled with other eligible upgrades through the assessment stream. Better insulation lowers heating bills and helps stop ice dams.

Eligibility, amounts, and requirements are set by the program — our team will confirm how it applies to your home and handle the details with you. Full details at homerenovationsavings.ca.
