Acrylic
Acrylic window inserts are a lightweight and cost-effective option for custom window inserts, making it easy to install, remove, and retrofit. When paired with a proper air gap and airtight seal, acrylic provides effective sound reduction, improved energy efficiency, and UV protection, helping create a quieter and more comfortable indoor space.
Acrylic inserts are well suited for budget-conscious projects where weight, removability, and overall value matter most. While laminated glass offers higher sound control in demanding environments, acrylic remains a practical and proven solution for many homes and buildings.

Laminated Glass
Laminated glass provides the highest level of sound control for custom window inserts. Made from two layers of glass bonded with a clear interlayer, laminated glass absorbs vibration rather than transmitting it, which significantly reduces both high-frequency and low-frequency noise.
In addition to superior sound reduction, laminated glass offers strong UV protection, improved security, and long-term durability. This makes it the preferred option for homes and buildings where maximum performance and comfort are required.

Tempered Glass
Tempered glass is a strong, durable option for custom window inserts and is commonly selected for safety, clarity, and building code compliance. The heat-treated glass offers excellent impact resistance and long-term durability, making it a reliable choice for both residential and commercial applications.
Tempered glass provides moderate sound reduction and performs well in everyday noise conditions. While it does not offer the same level of acoustic damping as laminated glass, it remains an effective solution when strength, safety, and structural performance are the primary considerations.

EXCELLENT Based on 72 reviews Posted on Steve ColeTrustindex 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.Posted on Patrick DuncanTrustindex 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.Posted on Steffen STrustindex verifies that the original source of the review is Google. Works better than expected, it is indeed sound proofingPosted on Terry He (何天宇)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!Posted on Larissa KatzTrustindex 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.Posted on Teresa BernaudoTrustindex verifies that the original source of the review is Google. Martin and Rashad did a great job, measuring and installing, the head office staff were very professional in coordinating the work and we are very happy with the noise reduction results! Highly recommended!! Thank you Magnetite!!!Posted on Adhiraj SinghTrustindex verifies that the original source of the review is Google. Great product! We got these for our floor to ceiling windows in our condo downtown, to get rid of the hum from the highway that our stock windows just didn't do a very good job of cutting out. Was a bit unsure how much of a difference they'd make, but it sure was significant and has brought a ton of calm & quiet to the room, haha. Alfredo & Martin were excellent through the process - precise communication and were on time for measurements & installation. Even though initially they had said it might be a couple of weeks, I think they had them ready and installed in pretty much a weeks time.Posted on Terry TaylorTrustindex verifies that the original source of the review is Google. Martin did a great job making sure the measurements were accurate and installation was performed with care. He explained how to maintain the inserts and made sure everything was cleaned up after install. And Alfredo, thank you for the early delivery! We are very happy with the inserts… yes, they work!!Posted on Carmen L.Trustindex verifies that the original source of the review is Google. I live on a major street and my daughter was complaining about the noise of the cars passing by during the nighttime when she was trying to sleep. Alfredo responded promptly via email and Martin, their installer, came on the same day that I confirmed to take measurements of my windows. The window inserts were ready the following week. Martin did a fantastic job on the installation and it only took him about 30-45mins. Although Alfredo mentioned a 70% reduction in noise, I’ve noticed it to be much more. I cannot hear cars passing by anymore unless they have a loud exhaust or it’s a big truck. The most important thing is my daughter now sleeps well and has not mentioned even a single time about hearing the cars since we’ve installed the inserts. I am grateful to Magnetite, Alfredo, and Martin for their service and customer care. Thank you!

FAQs
What are patio door inserts?
Patio door inserts are custom interior panels designed to fit over existing sliding or patio doors. They create an added insulating layer that improves comfort, reduces noise, and enhances energy efficiency without replacing the original door.
How do patio door window inserts help reduce noise?
Patio door window inserts reduce noise by adding an additional barrier and increasing the air space between the insert and the existing glass. This design helps block outside sound and is especially effective for patios facing busy streets or shared outdoor spaces.
Are patio door inserts available for sliding doors?
Yes. Patio door inserts are commonly used on sliding doors and function similarly to sliding window inserts. They are custom made to ensure a tight fit that minimizes drafts, vibration, and sound transfer.
What materials are patio door inserts made from?
Patio door inserts are available in several material options, including acrylic window inserts and glass. Acrylic options, sometimes referred to as plexiglass door inserts, are lightweight and impact resistant, while glass options offer a more traditional feel.
Can patio door inserts improve energy efficiency?
Yes. By sealing air gaps and adding an extra insulating layer, patio door inserts help reduce heat loss in winter and heat gain in summer. This can lead to more stable indoor temperatures and lower energy costs.
Will patio door inserts affect how my door operates?
Patio door inserts are designed to work alongside your existing door system. They install on the interior side and do not interfere with normal door operation when properly measured and installed.
Are specialized inserts available for large or unique patio doors?
Yes. Specialized inserts are available for oversized doors, multi panel patio doors, and unique configurations. Each insert is custom measured to ensure proper fit, performance, and ease of use.
Are patio door inserts removable?
Yes. Patio door inserts are fully removable, making them easy to clean or remove seasonally if needed. This provides flexibility for homeowners who want a non permanent upgrade.
