Climate Control & Energy Saver Window Inserts
Save up to 30% on energy bills with energy saver window inserts designed to improve comfort year round. Magnetite helps prevent heat loss through windows and reduces heating and cooling costs without the expense or disruption of window replacement.
Engineered for Energy Efficiency
Magnetite Canada helps homeowners improve comfort and efficiency by upgrading existing windows, not replacing them. Windows are one of the largest sources of heat loss in a home, especially through air gaps, frames, and single pane glass.
Magnetite energy saver window inserts install on the interior to create a sealed insulating layer that reduces drafts and improves thermal performance. This retrofit approach is widely used across energy efficient windows in Canada because it delivers meaningful results while preserving the original windows and architecture.

What Our Customers Are Saying
EXCELLENT Based on 72 reviews Posted on Steve ColeTrustindex verifies that the original source of the review is Google. I work from home and couldn't stand the sound of passing traffic and screaming kids on my street. I got Magnetite windows installed and it cut the noise right down. Of course nothing is 100%, but Magnetite windows made a massive difference. And they cost me next to nothing compared to what brand new soundproof windows would've costed. Alfredo and his team are pros. Highly recommended if you want a more peaceful home for a very reasonable price.Posted on Patrick DuncanTrustindex verifies that the original source of the review is Google. Solid 4.5, thank you to Alfredo and Jaskaran for the setup and installation! There is definitely a noticeable decrease in traffic noise, so it does work. I subtracted 0.5 since there are slight scuffs and marks on new frame, but that’s me being a perfectionist.Posted on Steffen STrustindex verifies that the original source of the review is Google. Works better than expected, it is indeed sound proofingPosted on Terry He (何天宇)Trustindex verifies that the original source of the review is Google. Martin and Rashad did an excellent job installing a custom-fit entire floor-to-ceiling wall of Magnetite window inserts for my guest bedroom in my condo. We were having a common issue of some construction noise in a busy Toronto location. The bedroom has been quiet and serene ever since the installation. For the amount of glass, customized fabrication, and professionalism/friendliness from Martin, I think the price was worth it for our result. I highly recommend Martin and would definitely work with him again. Thank you guys!Posted on Larissa KatzTrustindex verifies that the original source of the review is Google. I was so extremely happy to have found a solution for soundproofing our windows. The level of service provided by Magnetite Canada was exceptional. I had a very tight deadline for the production and installation of the panels, and all my requests were accommodated and treated with utmost care. I am forever grateful for Alfredo for speeding up the production, and for Martin for his excellent and efficient work on the installation. This company is not only professional, but they also treat you with care and attention.Posted on Teresa BernaudoTrustindex verifies that the original source of the review is Google. Martin and Rashad did a great job, measuring and installing, the head office staff were very professional in coordinating the work and we are very happy with the noise reduction results! Highly recommended!! Thank you Magnetite!!!Posted on Adhiraj SinghTrustindex verifies that the original source of the review is Google. Great product! We got these for our floor to ceiling windows in our condo downtown, to get rid of the hum from the highway that our stock windows just didn't do a very good job of cutting out. Was a bit unsure how much of a difference they'd make, but it sure was significant and has brought a ton of calm & quiet to the room, haha. Alfredo & Martin were excellent through the process - precise communication and were on time for measurements & installation. Even though initially they had said it might be a couple of weeks, I think they had them ready and installed in pretty much a weeks time.Posted on Terry TaylorTrustindex verifies that the original source of the review is Google. Martin did a great job making sure the measurements were accurate and installation was performed with care. He explained how to maintain the inserts and made sure everything was cleaned up after install. And Alfredo, thank you for the early delivery! We are very happy with the inserts… yes, they work!!Posted on Carmen L.Trustindex verifies that the original source of the review is Google. I live on a major street and my daughter was complaining about the noise of the cars passing by during the nighttime when she was trying to sleep. Alfredo responded promptly via email and Martin, their installer, came on the same day that I confirmed to take measurements of my windows. The window inserts were ready the following week. Martin did a fantastic job on the installation and it only took him about 30-45mins. Although Alfredo mentioned a 70% reduction in noise, I’ve noticed it to be much more. I cannot hear cars passing by anymore unless they have a loud exhaust or it’s a big truck. The most important thing is my daughter now sleeps well and has not mentioned even a single time about hearing the cars since we’ve installed the inserts. I am grateful to Magnetite, Alfredo, and Martin for their service and customer care. Thank you!

Our Customers Frequently Asked Us
FAQ’s
How do Magnetite energy saver window inserts improve efficiency?
Magnetite energy saver window inserts improve efficiency by sealing air gaps and adding a secondary interior glazing layer to existing windows. This creates an insulating air space that helps prevent heat loss through windows and stabilizes indoor temperatures year round.
Can Magnetite really help prevent heat loss through windows?
Yes. Windows are a major source of heat loss, especially when air leaks are present. Magnetite inserts use a continuous magnetic seal to close gaps around the frame, helping reduce heat loss through windows and limit drafts.
Are all Magnetite insert materials energy efficient?
Yes. Acrylic, tempered glass, and laminated glass inserts all work within the same double glazing retrofit system. Energy performance is influenced by material choice and thickness, but all options are designed to improve insulation compared to a single pane window.
Does thickness matter for energy efficiency?
Yes. Thicker inserts, such as 6mm options, provide greater thermal resistance than thinner panels. Combined with the sealed air space, thicker inserts can further reduce heat transfer and improve comfort in colder climates.
How does Magnetite compare to full window replacement for energy savings?
Magnetite offers many of the benefits of energy efficient windows in Canada at a lower cost and with less disruption. Instead of replacing windows, Magnetite upgrades existing ones, reducing waste and installation time.
Will Magnetite help reduce condensation on windows?
Yes. By improving insulation and stabilizing interior glass temperatures, Magnetite inserts help reduce condensation buildup and moisture issues around window frames and sills.
Are plexiglass window inserts energy efficient?
Plexiglass window inserts, commonly referred to as acrylic inserts, are a popular option for improving insulation. When installed as part of the Magnetite system, they help reduce air leakage and improve overall energy performance.
How much can I save on energy bills with Magnetite?
Energy savings vary based on home type, window condition, and climate. Many homeowners report savings of up to 30 percent on heating and cooling costs after installing Magnetite inserts.
Is Magnetite a good option for older or single pane windows?
Yes. Magnetite is especially effective for older or single pane windows, where heat loss is more common. The retrofit system upgrades performance without altering the original window frames or appearance.
