Stop Condensation on Windows Without Replacement

Stop condensation on windows and create a window moisture barrier with our window and patio door insert solutions. Stop mold growth and create a healthier environment in your home.

why condensation happens

Condensation occurs when warm, moisture-laden indoor air comes into contact with a cold window surface, causing water droplets to form. Designed for Canadian climates, Magnetite creates an effective window moisture barrier that helps regulate surface temperature to stop condensation on windows. This proven approach to glass condensation prevention helps prevent moisture on windows, reduce fogging and dripping, and ultimately stop window condensation while improving overall comfort and energy efficiency year-round.

How Magnetite Stops Condensation

Magnetite inserts add an insulating interior layer that keeps glass warmer, helping stop window condensation and prevent moisture on windows that can lead to mold and damage.

01

Airtight Magnetic Seal

The magnetic perimeter seal creates an airtight closure that blocks drafts and outside air infiltration. This seal acts as a window moisture barrier, preventing cold air from lowering glass temperatures and stopping moisture from entering through gaps around the window frame.
02

Insulating Air Space

Magnetite creates a sealed air space between your existing window and the insert. This insulating layer keeps interior glass surfaces warmer, reducing the temperature difference that causes condensation to form.

03

Interior Humidity Control

By reducing cold spots and drafts around windows, Magnetite helps balance indoor humidity levels. Warmer interior glass stays above the dew point, allowing homes to maintain comfortable humidity without excess moisture collecting on windows. This helps prevent window condensation during winter and shoulder seasons.

key advantages

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.

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.

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!

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.
