WHY RETROFIT VS REPLACE?
Minimal Disruption
Installed from the interior with quick turnarounds and after-hours options — ideal for occupied buildings and hotels.
Noise Reduction
Interior air cavity and acoustic-grade acrylic reduce outside noise — ideal for heritage urban cores near traffic or transit.
Energy Efficiency & Comfort
Sealed air cavities and non-vibrating acrylic panels can reduce outside noise dramatically and improve
Budget & Sustainability
Lower capex vs. replacement and fewer materials to landfill; leverage existing frames to reach performance targets faster.
Low Impact & Compliant
Installs from the inside, avoids exterior alteration, and remains fully reversible — aligning with conservation standards.
Preserve Exterior Façade
Maintain the building’s look and any heritage requirements while improving performance from within.
key advantages
Warm Homes. Lower Bills. Better Living.
In many Canadian homes, windows are one of the biggest sources of both sound transfer and heat loss. Continuous exposure to outside noise and cold drafts can lead to poor sleep, stress, headaches, and higher energy bills.
Magnetite energy saver window inserts are designed to tackle both problems at once. By creating an additional insulating air gap, our glass and plexiglass window inserts help prevent heat loss through windows while dramatically reducing outside noise. The result is a quieter, warmer, and more comfortable space that supports better sleep, improved focus, and lower heating costs.
As a smart upgrade for energy efficient windows in Canada, Magnetite inserts are a practical way to reduce heat loss through windows without replacing your existing frames. Better acoustics and better insulation equal better living.

Our Customers Frequently Asked Us
 FAQ’s
What are energy saver window inserts?
Energy saver window inserts are interior panels installed over existing windows to improve insulation. They help create a sealed air space that reduces drafts and improves overall comfort without replacing the original windows.
How do window inserts help prevent heat loss through windows?
Window inserts add an insulating layer that limits air movement and heat transfer. By sealing gaps and trapping still air, they help prevent heat loss through windows, especially during colder months.
Can window inserts reduce heat loss through windows in winter?
Yes. One of the main benefits of window inserts is their ability to reduce heat loss through windows by improving the thermal performance of older or less efficient window systems.
Are plexiglass window inserts energy efficient?
Plexiglass window inserts are lightweight and provide strong insulating performance. They are commonly used to improve energy efficiency while maintaining clarity and durability over time.
How do window inserts compare to energy efficient windows in Canada?
Window inserts offer many of the benefits associated with energy efficient windows Canada homeowners look for, such as reduced drafts and improved insulation, without the cost or disruption of full window replacement.
Do energy saver window inserts work in all climates?
Yes. Energy saver window inserts are designed to perform well in a range of climates, including regions with cold winters and seasonal temperature changes, by improving indoor thermal comfort.
Can window inserts help lower heating and cooling costs?
By reducing drafts and improving insulation, window inserts can help stabilize indoor temperatures, which may lead to lower heating and cooling demands over time.
Are window inserts suitable for older or existing windows?
Yes. Window inserts are often used to upgrade the performance of existing windows, making them a practical solution for improving efficiency without altering the original window structure.
