Find the Right Energy-Efficient Windows for Your Home

In Canada, energy-efficient windows usually have an Energy Rating of at least 34 or a U-factor of 1.22 W/m²·K. However, the best windows for your home depend on your location, local climate, how much sun or wind your windows get, and your current heating and cooling costs.

Our experts consider more than just the window label. We review local weather, what homeowners need, common house styles, and which window packages are popular in each area. Check the table below to find the recommended energy specs for your city, compare glass package options, and see a realistic price range before you plan your replacement.

City	Recommended window energy specs	Best fit	Approximate Price per window
Vancouver	U-factor ≤ 1.22 or ER ≥ 34	Sliding vinyl windows with strong drainage, Low-E glass, quality sealing	$1,220 – 1430
Calgary	U-factor ≤ 1.05 or ER ≥ 40	Triple-pane casement or awning windows with durable seals	$1,180 – 1,320
Edmonton	U-factor ≤ 1.05 or ER ≥ 40	Triple-pane vinyl windows, fixed/casement styles	$1,180 – 1,320
Winnipeg	U-factor ≤ 1.05 or ER ≥ 40	Triple-pane windows with excellent air leakage performance	$1,120 – 1,390
Ottawa	U-factor ≤ 1.05 or ER ≥ 40	Triple-pane casement, tilt-and-turn, or fixed windows	$1,240 – 1,490
Halifax	U-factor ≤ 1.22 or ER ≥ 34	Vinyl windows with quality weep holes and exterior sealing; single/double hing windows	$1,180 – 1,320
Regina	U-factor ≤ 1.05 or ER ≥ 40	Triple-pane hung or crank windows	$1,110 – 1,350

Double Pane vs Triple Pane Windows – What’s the Difference?

Nowadays, double pane windows are standard for Canadian homes. Two layers of glass with the Argon gas between them make these units a perfect match for most Canadian homeowners. Thanks to the fantastic thermal performance, you enjoy cool in summer and warm in winter.

As the name suggests, triple pane windows have three layers of glass, which makes them up to 50% more energy efficient than double-glazed units.

With Ecoline, you can install Energy Star triple pane windows or certified double-pane models. Whatever your choice, your home will benefit greatly after replacing your old units.

What Makes Energy Efficient Windows?

To be recognized as energy-efficient, any window must be certified by ENERGY STAR® and meet specific U-factor (measures heat loss), Air leakage, Visible light transmittance (measures light penetration), and Solar heat gain coefficient (measures heat gain), which contribute to the overall window energy rating (ER).

Stop Drafts and Leaks in Your Home

Old windows don’t just lose heat, they also drain money out of your pocket. New ENERGY STAR® rated windows are specifically designed for your location.

Low-E: Warmer in the Winter, Cooler in the Summert

The glass in our windows comes with a Low-E coating.
Rooms that get a lot of direct sunlight can overheat during the day. Low-E glass reflects sun rays away from the house and keeps your home comfortable.
There are different Low-E coatings based on how much sunlight you want to block. The same technology stops heat from escaping your home during the winter, reducing heating costs.

For maximum comfort and efficiency, thermal windows feature key elements in their construction:

High-performance triple-pane or double-pane glass

Argon or Krypton gas to fill the gaps between panes, making the windows even more efficient

Low-E coating during the winter retains heat inside while keeping the cold air out

Energy Efficient Replacement Windows – Options & Features

The benefits of energy efficient windows are endless. But to get the maximum out of your replacement project, you need to install the best-performing models equipped with modern energy-efficiency features.  At Ecoline, we tailor-made your new windows specifically for your home and its conditions, utilising cutting-edge technologies to manufacture high-efficiency windows.

Argon and Krypton Gas

Argon and Krypton gases conduct up to 50% less heat than air. Using these gases to fill the spaces between double and triple pane windows protect against heat loss, condensation and cold weather for increased energy cost savings and overall comfort.

SuperSpacer

Our windows are equipped with Super Spacer – a cutting-edge sealing technology that makes your new units more energy efficient and soundproof. Unlike most metal-based spacers, Super Spacer’s all-foam solution blocks heat flow and drastically reduces the condensation. It endures the 140°F temperatures and 95 – 100% humidity.

Multiple Glazing Options

A variety of glazing options are available for the best possible structural integrity. Traditional double glazing has a 7/8″ overall thickness (OT.) Triple glazing options are 1-3/8″ for awning, casement, casement fixed and picture windows. All triple glazing options for sliders and hung windows are 1-1/4″ with no grill limitations.

True Multi-Chamber Design

To improve structural performance and sound insulation plus reduced warping, all Ecoline window styles utilize a true multi-chamber design.

Up to 10% Thicker PVC Profile Walls

Ecoline incorporates 7% to 10% thicker PVC profile walls than industry average for all awning, casement, casement fixed and picture windows. They are also engineering to comply with heavier, large windows and triple-glazed glasses.

Screen Groove Port Design

Casement and awning windows now incorporate a new screen groove port design for improved push-down screen fit.

FAQ

What are the most energy-efficient windows?

The most energy-efficient windows typically feature triple-pane glass, low-E coatings, vinyl frames and are often filled with argon or krypton gas. Picture and casement windows rank highest in energy efficiency due to their airtight designs.

Which is more energy-efficient: single-hung or double-hung windows?

Single-hung windows are generally more energy-efficient than double-hung windows due to fewer moving parts and better air tightness.

How much do energy-efficient windows cost?

The cost of energy-efficient windows varies widely based on material, glass type, size, and custom options. On average, homeowners can expect to spend around $1100 per standard triple pane casement window. You can use our replacement cost window estimator to find the average price for any window style.

Are casement windows more energy-efficient than sliders?

Yes, casement windows are typically more energy-efficient than sliding windows. The seal on casement windows tightens when closed, which reduces air leakage. However, all Ecoline sliders meet the highest industry standards and provide sufficient energy efficiency for any Canadian home.
