ESIONX magnetic seals provide one of the lowest air infiltration rates of any operational window. Our slim extruded framing allows us to maximize the air gap for all window types. Furthermore, ESIONX uses acrylic glazing, which is safer and lighter than glass. Window seal is able to use safer, more manageable acrylic with a larger air cavity. Acoustical window seals inserts are non-operable, add-on window inserts designed to reduce noise through your existing window. Our noise reducing window seals use an insert track that is designed to accommodate a W¨ thickness glass or acrylic.
The more distance you have between the existing window and our acoustical window seal insert the better the insulating and noise dampening results. The window seal track is factory cut to custom sizes with mitered corners, and mounting screws (provided) to secure the system to or around your existing window frame.
The performance of the window seal is brilliant. Window seals reduce the amount of the noise pollution from 400Hz to 20,000Hz. This solution is optimal for reducing noise from busy roads, commuter trains, and noisy neighbours.

* STC is the Sound Transmission Class of the window and is measured over a range of frequencies. The STC represents the corrected, average reduction in decibels (dB) measured at 500Hz.
