SOUND TRANSMISSION

An STC (Sound Transmission Control) rating is a measure of how well a building product reduces sound transmission.  

​

The higher the number, the better job a product does at keeping sound out.

​

Many factors impact sound transmission.  In windows, varying the thickness of the two panes of glass or utilizing laminated glass are ways to reduce sound transmission.

​

The Coeur d'Alene Window Company offers a standard "sound control" glass package that incorporates 3.7mm glass with 3.0mm glass as an economical way to reduce some sound transmission.
