after inside window installed, It’s much much better than before. It blocks noise at least 80%, I don’t hear anything from outside almost. Really appreciate you and your company solving my pain point.Posted on Google![]()

What a wonderful administrative team in Ontario and installation team in BC. Professional, responsive and...real people. The magnetite inserts themselves are a fantastic solution for our needs. Excellent sound and thermal protection.Posted on 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 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 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 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 Google![]()
