Choose your priority—we’ll route you to the right Magnetite page. Full proof and FAQs live on each solution page.

Reduce outside noise

Traffic, aircraft, construction, and street noise through the window area—up to 70% noise reduction under suitable conditions. Not a guarantee of complete soundproofing.

Improve climate & drafts

Extra sealed air space to support more stable indoor temperatures and fewer drafts. Energy outcomes vary (advertised up to 30% heating/cooling savings under suitable conditions).

UV protection & privacy

Options intended to reduce UV exposure and add privacy while keeping daylight.

Condensation control

Better insulation at the glass can support condensation control. Results depend on humidity, ventilation, and building conditions—Magnetite does not guarantee elimination of moisture.

 Trustindex verifies that the original source of the review is Google. 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.

The magnetite inserts themselves are a fantastic solution for our needs.  Excellent sound and thermal protection.

 Trustindex 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.

 Trustindex 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.

 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!

 Trustindex 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.
