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 health 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

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.

02

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.
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

Welcome to a Moisture-Free Home

Magnetite inserts create an airtight seal and buffer that stops condensation on windows in cold Canadian climates. This protects windows and frames from moisture damage, helps fight mold and mildew, and maintains clear, frost free views throughout the year.


As a retrofit solution, Magnetite installs quickly from the inside, reduces material waste compared to full window replacement, and delivers a cost effective and sustainable upgrade that improves comfort, indoor air quality, and energy performance.
