Soundproof Window Inserts for Noise Reduction

Cut down outside noise by up to 70 percent with soundproof window inserts, without replacing your existing windows. Magnetite transforms loud spaces into quieter, more comfortable environments while preserving the look and function of your home.

A Smarter Way to Block Noise

Magnetite soundproof window inserts are interior retrofit panels that seal tightly to your existing windows and patio doors using a magnetic mounting system. By adding a secondary interior layer and an airtight seal, Magnetite significantly reduces outside noise without replacing your windows.

Designed as high-performance acoustic window inserts, Magnetite solutions are effective for traffic, trains, aircraft, construction, and other everyday noise sources.

how magnetite works

The Science of Silence

Standard windows and patio doors provide minimal noise protection. When sound waves hit glass, vibration transfers noise directly into your space, especially through small gaps and poor seals.

Magnetite addresses this with soundproof window inserts that add a secondary interior glazing layer. This creates a sealed air cavity between your existing window and the insert, disrupting sound waves before they enter your home.

3 Core Components of the Sound Insulation System

01

The Air Buffer

Magnetite inserts create a controlled air gap between your existing glass and the interior panel. This dead air space absorbs and weakens sound waves, forming the foundation of effective noise reduction.

02

Performance Glazing Layer

Magnetite inserts are available in multiple glazing options selected based on performance needs. The added interior layer helps dampen vibration and reduce sound transmission compared to a single pane window.

03

Magnetic Sealing System

A continuous magnetic seal locks the insert tightly in place, eliminating gaps where sound travels. This airtight perimeter helps block both high-frequency noise like voices and sirens, and low-frequency noise like traffic and aircraft rumble.

Soundproof Window Inserts vs
Other Noise Reduction Options

There are several ways to reduce window noise, but not every option gives the same level of comfort, performance, or long-term value. Some solutions are quick fixes, while others require full window replacement. Magnetite window inserts are designed for homeowners, condo owners, offices, and commercial spaces that want better sound control without removing their existing windows.

Noise Reduction Option Best For Things to Consider
Magnetite Soundproof Window Inserts Reducing outside noise without replacing existing windows Custom-fitted to your window and installed on the inside, creating an added sealed layer and air gap for better noise control
Full Window Replacement Old, damaged, or failing windows that need a complete upgrade Usually costs more, takes longer to install, and may not be necessary if your existing windows are still in good condition
Acoustic Curtains Bedrooms, rental spaces, or temporary noise support Can reduce some sound, but they block natural light and do not seal the window opening
Weatherstripping and Caulking Small gaps, air leaks, and minor drafts Helpful for sealing leaks, but usually not enough for traffic, train, construction, or city noise
DIY Acrylic Panels Low-budget projects or short-term use Performance depends heavily on fit, seal, material quality, and installation accuracy

Enhanced Living Comfort

Proven Acoustic Performance by Window Type

Magnetite soundproof window inserts deliver measurable acoustic improvements across different existing window systems. Depending on the base window type and final configuration, Magnetite can achieve up to STC 43 for single-pane wood windows and up to STC 46 for double-pane aluminum windows. That means stronger noise control without replacing the original windows for homes and buildings affected by traffic, trains, aircraft, and other urban noise.

A smooth-glide PVC guide channel allows the insert to open and close easily, while a vertical handle strip supports effortless use. Magnetite ProCore inserts deliver a quieter, more comfortable space while preserving full window and door functionality.

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.

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.

Frequently Asked Questions

Magnetite window inserts can reduce outside noise by up to 70 percent under suitable conditions, depending on window type, wall construction, noise frequency, insert configuration, cavity depth, and installation. They are commonly used for traffic, trains, aircraft, construction, and urban noise. Results vary; Magnetite does not guarantee a specific reduction for every opening.

Magnetite adds a sealed interior acrylic panel that creates a controlled air gap between your existing window and the insert. That airtight cavity plus added mass helps disrupt sound waves and limit vibration transfer through the window area compared with an unsealed single pane.
No system actively cancels sound electronically at the window. Magnetite uses acoustic principles—spacing, mass, and airtight sealing—to reduce high- and low-frequency noise. Prefer calling them acoustic or noise-reduction inserts.

Yes—Magnetite is commonly used near busy roads, rail lines, flight paths, and construction zones. Effectiveness still depends on the building envelope (walls, flanking paths, open vents) and the insert configuration chosen after assessment.

No. Magnetite is a retrofit secondary-glazing system. Your existing windows stay in place; inserts install from the interior with no exterior change to the façade.
Magnetite inserts use acrylic, typically in 3 mm and 6 mm options, with systems such as ProCore and SlimLine. Selection depends on performance goals, opening size, and installation constraints.
Inserts are custom-measured for a clean, low-profile interior fit. From outside, the original appearance is largely preserved—useful for condos and heritage exteriors where replacement is restricted or undesirable.
The continuous magnetic seal limits air leakage as well as sound paths at the window. That can reduce drafts and support more stable indoor temperatures. Energy outcomes vary; Magnetite’s broader claim of up to 30% heating/cooling energy savings is a qualified first-party claim dependent on building and climate (see climate-control pages for detail).
Many projects are completed in one day after inserts are measured and manufactured. Larger or more complex projects may take longer.
No. No window treatment can guarantee complete soundproofing. Magnetite should be described as a noise-reduction or acoustic retrofit solution. Some sound may still be heard, especially low-frequency rumble or noise entering through walls, floors, vents, or other flanking paths.

Replacement can make sense when windows are failing structurally. If the glass and frames are otherwise sound, interior inserts often deliver strong acoustic improvement without the cost and disruption of full replacement. Magnetite Canada states the system can cost approximately 40–60% less than full replacement; exact pricing depends on openings, thickness, access, and location. Get an estimate.

 

Results depend on: existing window type and condition; wall and building construction; size of the glazed area; air gaps and seals; noise type and frequency (traffic vs voices vs aircraft); insert thickness and system; air-cavity depth; and quality of professional measurement and installation. An on-site or photo-based assessment helps set realistic expectations.
Yes. Inserts are designed to work with existing windows and can be removed for ventilation, cleaning, or maintenance. Exact operation depends on the window and selected insert configuration (including patio-door inserts where applicable).
Often yes—especially when exterior replacement is restricted by the condo board or landlord. Interior inserts improve the window portion of the sound path without changing the exterior. They cannot fix noise that enters primarily through walls, floors, or shared mechanical systems; assess flanking paths before expecting whole-unit silence.
If most noise enters through poorly insulated walls, open vents, patio doors left untreated, or structural flanking—not the window glass—inserts alone will under-deliver. Severe structural window failure may need repair or replacement first. Magnetite can advise after reviewing your openings and noise sources.

No. Magnetite products are interior acrylic secondary-glazing inserts, not traditional exterior storm windows. They add an interior sealed layer for acoustics and comfort while preserving the exterior look. (Storm-vs-insert detail is expanded in Update B on the storm/commercial cluster.)
