Yes, you can dampen noise pollution by up to 95% depending on the type of window, material of the window, and number of glass panes.
The “STC” or Sound Transmission Class is the rating system used to determine the noise reduction capacity of the window. The higher the STC rating the better the sound proofing. STC ratings typically range from 25 – 55.
Not all windows have an official STC rating as this rating system is a certification process that manufacturers need to undergo. However, this does not mean that that window will not substantially help with noise reduction.
What makes the biggest difference when it comes to sound proofing a window is the of the seal, and number and thickness of glass panes. Applying a laminate layer on the glass, will also further help with this. The optimal operable window type is a Casement that is triple pane with 4mm- 6mm glass that is also laminated.
Most modern vinyl and aluminum windows will drastically reduce sound transmission even if they only have two panes of glass.
Interlink Doors & Windows works with a number of vendors to get the correct solution for your particular soundproofing needs.
Are Soundproof Windows Worth it?
Yes, they are if you have noise pollution issues.
Unless you are facing a busy street, or you have train tracks running near your home, a standard two-pane window will be more than sufficient to help dampen sound transmission.
Are Soundproof Windows Expensive?
Windows that have the highest STC certified value can be costly. However most applications do not require the highest possible STC rating. In most situations simply upgrading to triple pane casement windows will prove above adequate. This will only affect the price of each hwindow by about 10-15%
How Do You Soundproof Windows Without Replacing Them?
You can help dampen sound transmission through existing windows by doing the following:
- Remove the trim around the window and see if you have adequate insulation foam around the window. If not apply more. Be cautious when doing this as applying to much may damage your window.
- Replace the rubber weather seals with heavy duty ones. You can buy these at your local hardware shop or window parts depot. Measure out how much linear feet you need and add 10% to that number just in case.
- Replace the glass on your windows. These are called sealed units. Glass manufacturers can provide you with Argon Filled sealed glass unites with varying thickness of glass. This will require some more advance know-how.
- Laminate your existing glass. There is no such thing as soundproof film however, a clear robust piece of laminate will further help with reducing sound transmission.
- Seal any noticeable voids around the exterior of the window with silicone and/caulking.
