Energy Rating (ER)

A composite score combining solar heat gain, heat loss and air leakage. Higher ER values generally indicate better overall energy performance in Canadian climates.

U-Value

Measures heat transfer through the window assembly. Lower U-Values indicate better insulation performance and warmer interior glass surfaces in winter.

SHGC

Measures how much solar heat enters through the glass. Different SHGC levels may be beneficial depending on orientation and climate — higher for passive winter warmth, lower for summer heat control.

Why Triple-Pane

Compared with double-pane, triple-pane assemblies typically improve:

  • Thermal comfort near the window
  • Interior glass temperature during winter
  • Condensation resistance in cold weather
  • Overall energy efficiency
  • Whole-building thermal performance
  • Acoustic performance in mid frequencies

Performance ratings shown are based on testing recognized by Natural Resources Canada (NRCan) and include Energy Rating (ER), U-Value, and Solar Heat Gain Coefficient (SHGC) — the industry-standard metrics used by NRCan and ENERGY STAR® Canada. Values are derived from certified product testing of Trust Build window systems and may vary by size, configuration and glass package.

Not sure whether double or triple-pane is right for your home? Trust Build's specialists give you an accurate, side-by-side breakdown of the certified performance numbers for your exact windows and exposure — so you choose with full confidence, backed by data rather than guesswork.

Installation Methods

How Trust Build installs your windows

Installation quality is as important as glass performance, Energy Rating (ER), U-Value and SHGC. A premium window installed poorly will underperform a mid-tier window installed correctly. Trust Build is an installation-first company focused on proper building-envelope integration — here are the four methods we use and when each one is the right choice.

Brick-to-Brick Installation

Trust Build Premium Method

Trust Build's most common premium installation. The existing window is removed to the brick opening and the old frame is taken out. The opening and existing insulation are inspected, additional insulation is added where required, the new window is set into the original brick opening, the exterior perimeter is sealed and protected, and new aluminum capping is installed. Interior finishes are preserved where possible — this is not the same as a North American full-tear-out 'full-frame replacement'.

  • Larger glass area than retrofit installation
  • Better air sealing and perimeter insulation
  • Allows inspection of the opening condition
  • Maintains the original window size
  • Preserves interior finishes where possible

Best for: Homeowners who want maximum performance and proper envelope sealing without major interior reconstruction.

Stud-to-Stud Installation

Full Reconstruction

The most extensive installation method. The window and surrounding construction materials are removed and the opening is exposed to the structural framing. Damaged materials can be repaired or replaced, openings can be modified or resized, and new insulation and waterproofing are installed before the new window or door is set into the rebuilt opening.

  • Allows structural repairs
  • Allows resizing of openings
  • Allows window-to-door conversions
  • Provides complete access to the building envelope
  • Ideal for egress and major renovation projects

Best for: Enlarging windows, window-to-door conversions, structural repairs, egress window projects and major remodeling projects.

Learn more

Retrofit Installation

Insert Installation

The existing frame remains in place and the new window is installed within it. Interior and exterior finishes stay largely untouched — a faster, lower-cost option when the existing frame is in excellent structural condition. There is a slight reduction in glass area, and full inspection of the rough opening isn't possible.

  • Faster installation
  • Lower installation cost
  • Minimal disruption
  • Preserves existing interior and exterior finishes

Best for: Homes where the existing frame is structurally sound and free of water damage.

Learn more

Split-Frame Installation

Trust Build Specialty Method

A specialized method commonly used with vinyl windows. The exterior portion of the existing frame is removed while the interior frame components remain intact — existing interior casing and trim are preserved, and the new window is integrated into the existing interior frame structure. Provides more glass area than most retrofits and allows exterior weatherproofing upgrades.

  • Preserves interior finishes and existing trim
  • Minimizes drywall and repainting work
  • More glass area than most retrofits
  • Allows exterior waterproofing and capping upgrades

Best for: Homes with premium interior wood trim, recently renovated interiors, and vinyl window replacement projects where preserving interior finishes matters.

Not every home qualifies for retrofit or split-frame

Before recommending an installation method, Trust Build evaluates existing frame condition, moisture exposure, structural integrity, air leakage and the overall condition of the opening. The right method is determined after on-site inspection to ensure long-term performance and durability — not chosen on price alone.

Installation quality is equally important as glass performance, Energy Rating (ER), U-Value and SHGC values.

FAQ

Window Replacement — Frequently Asked Questions

There's no single answer — the best style depends on the room, exposure, and your priorities. Casement and tilt-and-turn windows provide the tightest energy seal and maximum ventilation. Picture windows offer the best thermal performance with no moving parts. Slider and hung windows suit traditional or heritage-style homes. Our specialists recommend the right style for every room and back the recommendation with the certified performance numbers when they quote your project.
Double-pane windows have two glass layers with one insulating gas chamber — a solid cost-effective upgrade for most Ontario homes. Triple-pane windows add a third glass layer and second gas chamber for superior insulation, noise reduction, and energy savings — the gold standard for Ontario winters. We provide the certified ER, U-Value and SHGC figures for both packages so you can compare them on data, not guesswork.
Yes — every window we install is Energy Star certified for Ontario's climate zone. This ensures the window meets minimum thermal performance requirements for our region and may qualify you for rebates through Ontario's Home Renovation Savings Program.
Most standard window replacements are completed in a single day. A full-home replacement of 10 to 15 windows typically takes one to two days. Our crew handles everything — removal, installation, cleanup, and disposal — and you receive a written warranty certificate before we leave.
Yes — old window removal and responsible disposal is included in every Trust Build installation at no extra charge. You do not need to arrange anything separately.
