Replacing your windows with ’soundproof’ windows will help performance.
If your wall has both a window and a door, then the window should be treated first since it is likely the weakest of the two (usually 10 STC points less than a door). Doors and windows are typically in the STC 20-30 range, much too low when compared to the average exterior wall. Either way, if your exterior wall has a door or window, then it needs to be addressed. A door or window that takes up most of the wall is more of an issue than a door or window that takes up 10% of the wall surface. The size of the door or window in relation to the size of the wall is important. The STC rating of your exterior wall will vary somewhere between STC 35 to 45 depending on the exterior finish with an OITC rating of approximately 35. However, without addressing the weakest points, the wall will be one expensive, and still pretty noisy, exterior assembly.Ī typical exterior wall consists of a layer of drywall, 2×4 framing, R-13 insulation, a layer of OSB sheathing, and either siding, stucco, or brick with the occasional window or door. Several products and wall assemblies will help with exterior noise reduction.
