Triple-Pane, Low-E, Argon-Filled Energy Efficient Windows in Edmonton.
Cut heating bills and condensation.
Energy Efficient Windows Edmonton | Triple Pane, Low-E & Argon Gas
Edmonton gets down to -40°C. Your windows are either working for you or bleeding heat and money every day of winter. Rally Glass installs energy efficient windows engineered for our climate — triple pane glass, Low-E coatings, and argon gas fills that dramatically reduce heat loss, condensation, and energy bills.
What Makes a Window Energy Efficient?
It’s not one thing — it’s the combination of glass layers, gas fills, and coatings working together. Here’s what goes into every energy efficient window we install:
Triple Pane Glass
Three panes of glass with two sealed air spaces between them. This is the single biggest factor in a window’s insulation value. Triple pane is the Edmonton standard — double pane is fine in Vancouver, but it’s not enough here.
Two insulating chambers vs. one (double pane)
Reduces heat loss by up to 50% compared to double pane
Virtually eliminates interior condensation in winter
Significantly reduces outside noise transfer
Argon Gas Fill
The space between each pane isn’t just air — it’s filled with argon gas. Argon is denser than air, which means it conducts less heat. It’s invisible, odourless, non-toxic, and it stays sealed inside the glass unit for the life of the window. Every window we install comes with argon gas fill standard.
Low-E Coating
Low-E (low emissivity) is a microscopic metallic coating applied to the glass surface. It reflects radiant heat back into your home in winter while blocking UV rays and solar heat gain in summer. You can’t see it, but your heating bill can feel it.
Reflects heat back inside during Edmonton’s 6-month winter
Blocks 95%+ of UV rays that fade furniture and flooring
Available in multiple configurations (Hard-coat, Soft-coat, Solar Control)
Double Pane vs. Triple Pane — Which Do You Need?
For Edmonton, our honest recommendation is triple pane in every case. Here’s why:
Double pane: R-value ~2.0. Adequate in moderate climates. Will still condensate in Edmonton’s coldest months.
Triple pane: R-value ~5.0+. Designed for extreme cold. Eliminates condensation and cuts heating costs dramatically.
The price difference between double and triple pane is typically $50–$150 per window. Over 15–20 years of Edmonton winters, triple pane pays for the upgrade many times over.
We will never upsell you on something you don’t need. But in this climate, triple pane genuinely is the right call.
Energy Rebates & Incentives
Alberta and federal energy programs periodically offer rebates for energy efficient window upgrades. Eligibility and amounts change, so ask us about current programs during your quote. We’ll help you understand what’s available and what documentation you need.

Window Styles Available in Energy Efficient Configurations
Every window style we offer is available in triple pane with Low-E and argon:
Casement windows — best air seal of any operable window
Bay & bow windows — custom-built, triple pane standard
Double hung — tilt-in for easy cleaning
Sliders — horizontal and vertical
Picture windows — fixed glass, maximum efficiency
Basement / egress windows
Energy Efficient Doors
Windows aren’t the only weak point. Entry doors and patio doors with poor insulation or single-pane glass are major heat loss sources. We install energy efficient entry doors with insulated cores and patio doors with triple pane glass.
Entry & exterior doors
Frequently Asked Questions
How much do triple pane windows cost?
Most homeowners spend $500–$1,200 per window installed, depending on size and style. Triple pane adds roughly $50–$150 over double pane per unit.
Is argon gas safe?
Yes. Argon is an inert, non-toxic gas that makes up about 1% of the air you breathe. If a seal fails and argon escapes, it simply dissipates harmlessly. You’d never notice.
How do I know if my current windows are energy efficient?
Look for condensation between panes (seal failure), frost on the inside of the glass in winter (poor insulation), or drafts near the frame. If your windows are more than 15–20 years old, they’re almost certainly not triple pane and are costing you money.
Do you offer an energy assessment?
During every free quote, we assess your current windows and explain what upgrading to energy efficient units would look like for your specific home. No charge, no obligation.
