Reduce Outside Noise by Up to 70% Through Your Existing Windows in Ontario
How does noise travel through your windows?
Outside noise enters a space when sound vibrations pass through glass and air leaks around window frames. Gaps, poor seals, and thin glazing allow noise and drafts to move freely indoors, reducing comfort and energy efficiency.
To limit noise transfer, a window system needs an airtight seal, an insulating air space, and materials that help dampen sound vibration.
Magnetite Canada’s Solution for Ontario
Magnetite provides custom window inserts in Ontario that install on the interior of your existing windows to create a sealed air cavity. This system functions as a modern alternative to traditional storm windows, helping reduce noise, block drafts, and improve insulation without replacing your windows.
Our soundproof window inserts, available in acrylic or glass, are also suitable for larger openings such as patio door inserts. Each insert is custom measured to support energy efficiency, making them a reliable option for energy saver window inserts in homes and buildings throughout Ontario.
Magnetite systems are tested to achieve extremely low air infiltration, helping maintain quieter, more comfortable indoor spaces year round.

Testimonials
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!
