What are soundproof window inserts?
Soundproof Window Inserts are 1/4" thick, laminated glass panels, installed between your existing window and your window treatments (blinds, shades, shutters, curtains, drapes). We do NOT have to replace or modify your existing window in any way.
We have three types of soundproof inserts:
- Operating Insert - This insert operates just like an regular sliding window. The lower sash slides up and down, or side-to-side to match the operation of existing sliding windows. In the case of existing windows that crank outward (casement style) we use the type that slides up from the bottom to provide access to the crank handle. This insert is the best choice for customers who regularly open their windows on the noisy side of the building. This is the most expensive option due to the higher cost of manufacturing.
- Single-piece Insert - This removable panel is the most popular insert. It is the least expensive and most effective insert because it has the least number of places to contribute sound leakage. It removes by pulling to release the magnetic frame from the steel frame. It meets fire code for ingress and egress and has no "cross bars" to interfere with your view. It is the best choice for customers who don't open their windows daily on the noisy side of the building.
- Two-piece Insert - This insert has two panels - an upper and lower. This upper/lower "split" makes it easier for customers to open their existing windows, because they only have to remove the lower panel to access the lock on their existing window. The cross bar is positioned in the same place as the cross bar of the existing window to lessen interference with your view. This insert is a good choice for customers who regularly open their windows on the noisy side of the building, but want to keep costs down. We also accommodate customers who have a left/right sliding configuration.
The frame is two parts: the magnetic/vinyl that fits around the edges of the laminated glass, and the steel L-angle that attaches to the wall. The magnetic half of the frame sticks to the steel half of the frame, creating an "active" seal.The steel frame is made of 26 gauge, coated galvanized steel with a rolled edge. It is brad-nailed to the wall and caulked to form a tight seal. The magnetic frame is vinyl with a UV inhibitor, rated at .9 pounds per linear foot of holding power.
All components are warranted against defect and workmanship for as long as you own your home.
Our windows have been tested by independent laboratories on several aspects of technical performance. The results are below:
U-value of .48 in combination with single pane window, as determined by John M. Yellott Laboratories, Arizona, in tests performed August 5, 1982.
Heat loss reduction of 412.5 BTU/hr/sg ft (from 687.0 to 274.5) when applied to single pane window. 60% net reduction of heat transfer. As determined by Architectural Testing Inc., York, PA, in tests performed January.
Less than .01 cfm/lineal foot crack space, compared to DOE standard for storm windows of 2.0. Tested with 25 mph wind equivalent at The Associated Laboratories , Dallas, using ASTM E-283 test method. Similar results at the John M. Yellott Laboratories, above.
The STC rating of a single pane window is STC 22-25; a double pane window is STC 27-32. Our soundproof window inserts installed with a single pane window obtains an STC rating of 40-44. A soundproof insert installed with a double-paned window obtains an STC of 48-50.
Ultraviolet Light (UV) Control
1/4" laminated glass - UV between 300 and 355 reduced by 99%; 360 and 375 reduced by 97%.
Magnetic Holding Force
12.1.2 lb/lin. ft, commercial grade
.9 lb/lin. ft, residential grade
Sound and Noise Ordinances
Sound Meter Apps for Smartphones
Sound Meter Apps are very helpful to determine differences in noise contribution of your walls and windows. Although, they are not as accurate as dedicated sound meters in terms of decibels, they will give you direct feedback regarding where the biggest sound problems are. Here's a link to a study by the CDC of sound measurement apps.CDC-Evaluation of smartphone sound measurement apps
