What is a Triple Pane Window?

Triple pane windows (also called triple glazed windows) are the most energy-efficient windows on the market today. Their Energy Rating (ER) is up to 48, while double pane windows have an ER of 26-34.

Buildmart works with the #1 manufacturer in Canada, STAGE Windows, to supply premium quality triple pane windows that will last you a lifetime. 

All STAGE Windows are ENERGY STAR® and NAFS-11® certified. The company is among an elite group of manufacturers earning these certifications for high standards of work. 

Triple pane windows have a high ER because they are exceptionally well-made. They deliver the highest quality of insulation and guarantee a comfortable temperature in your home year-round thanks to special features that protect your home against heat loss, cold weather, and condensation. Plus, they come in 12+ colours and are made custom to order, every time. 

Visit our Ottawa East and Kanata (by appointment only) showrooms to see the windows in person and check out the thickness of the glass, the hardware for opening and closing the window, and how simple it is to pop out the screen.


Double Pane Windows vs Triple Pane Windows

The biggest difference between double pane windows and triple pane windows is the extra pane of glass — thanks to this, triple glazed windows are more insulating, heavier and more durable. The extra compartment is filled with argon and krypton gases that conduct up to 50% less heat than air. When you have three panes of glass, the window conducts less heat and stops the cold from getting in.

A triple pane window will give you the highest energy savings — ER of a double pane window is between 26 and 34, while it is up to 48 for a triple pane window. Better Energy Ratings and insulation capacity mean energy cost savings and a lower hydro bill for you, year-round. 

Triple pane windows also improve your home’s value thanks to their reinforced structural integrity and additional security.

Our team loves installing triple pane windows in our clients’ homes because of the positive feedback we receive after installations — the windows’ functional design and thoughtful features make clients more comfortable, for decades to come. 

As with all Buildmart products, our triple pane windows are custom-made for each order which means you can choose the colour, style, design, and hardware to match your home perfectly. 


Are Triple Pane Windows for Me?

Since triple pane windows provide superior insulation, we recommend this type of window for your home if you live in a city with very cold winters, such as in the Ottawa Valley!

Triple pane windows are your best bet to minimize heat loss when temperatures drop. Conversely, with our heatwaves in the summer, triple pane windows will keep your coveted AC temperatures inside and reduce unnecessary heating of your home from the stark sunlight.

We also highly recommend triple glazed windows if you live in a noisy area, like near a highway, or at a busy intersection — it can be hard to sleep or work in peace and quiet if you are constantly hearing traffic or honking.

With the best noise reduction performance on the market, triple glazed windows are your ticket to peace of mind, for decades to come.


Triple Glazed Windows Cost

Triple glazed windows require more glass, plastic, and insulating gas to manufacture than double glazed windows and thus are about 20% more expensive than double pane which is reflected in the superior insulating and energy efficiency powers. 

The final cost of your triple glazed windows depends on your design choices, from the colour of the window to the interior and exterior finishes, and hardware. Every window is custom-made to order to ensure it is perfect for your home.

What Our Clients Say

Overall, the biggest feedback we receive form our happy clients after installation is how much more comfortable the home became thanks to the reduction in noise and superior heat & cold temperature insulation. Are you ready to enjoy your house to the fullest?

And, did you see that you can upgrade your custom order of double pane windows to triple pane for free for a limited time?!


Are triple pane windows really saving you the bills, if so, by how much?


While your energy bills depend on your wall structure, the condition of your home, what temperature you heat or cool your home to and other lifestyle factors, triple pane windows help you save at least 2-3% on your energy bills per year. You could be saving more if you live in a cold climate — like the Ottawa Valley — since you will be losing much less heat through your triple pane windows when you need to warm up your home when it’s -20 outside. Plus, you will feel more comfortable in your home and not need to do any maintenance for years.

Do triple pane windows fog up?


When there is a big contrast between cold and hot air, your windows may fog up on the outside. However, thanks to triple pane windows’ superior insulation and two pockets of insulating gases, you won’t see condensation or fog on the interior, or in the glass unit itself thanks to airtight seals and weather stripping features. Triple pane windows are one of the only options to combat windows often fogging up.

Are triple pane windows quieter?


Thanks to another pane of glass, triple glazed windows offer an extra barrier to loud noise like highway traffic which can be irritating when you are trying to sleep or work. Our clients always note how much quieter and more comfortable their home became after installing triple pane windows with Buildmart. While we won’t guarantee that your triple pane windows will be completely soundproof, we can say that you will feel more comfortable in your (quiet) house for decades to come.

What's the warranty?


Our windows come with maximum protection:
Lifetime warranty on frames & installation
20-year warranty on glass
15-year warranty on hardware
15-year warranty on paint
Fully transferable warranty

Will they ever pay off?


New windows for your home are a valuable investment. While triple pane windows are currently the best product on the market and will reduce your energy bills every month, we are transparent in sharing it may take 20-35 years to pay them off with the utility savings. By ordering your custom new windows from Buildmart, you can expect not only comfort but also a real chance for your windows to pay for themselves since they will serve you for a lifetime.

How long do triple pane windows last?


Triple pane windows are generally considered a luxury product. They are carefully constructed and last relatively longer than other types of windows. However, they may still need to be serviced after a few years. Overall, triple pane windows are known for lasting up to 25-30 years, offering fantastic longevity.
