Windows
Below you’ll find a compilation of window soundproofing technologies. The list is arranged by the cost of the solution, from high to low.
Solution: Custom Soundproof Windows
Cost: Expensive
Summary: The best window soundproofing solutions in the marketplace involve the installation of a laminated glass interior window in front of your existing window. Typically there is a 3-5 inch air gap between the two windows which is critical to reducing noise transfer. It is also important to have each window custom manufactured for your space because any gaps or filler materials that you use around the window will reduce your soundproofing levels. Different glass thicknesses are available and thicker glass offers additional soundproofing at a higher cost.
Solution: Semi-Custom Soundproof Windows
Cost: Expensive
Summary: These windows purport to be fully custom soundproof windows, but they don’t involve the full service of a custom designed soundproof window. Window measurements are adjusted so that multiple windows can be manufactured at once, but this means that more filler materials will be used around the glass and soundproofing will be impacted. Thicker levels of glass are also potentially not available because the extra weight would make shipping of these windows difficult.
Solution: Double-paned Windows
Cost: Moderate
Summary: Many modern windows employ a double or triple pane technology. While it is true that additional panes of glass will help reduce noise, the air gap between layers of glass is typically only a centimeter or less which impairs maximum soundproofing.
Solution: Specialty Window Blinds or Curtains
Cost: Moderate
Summary: If you are looking for a quick and inexpensive fix, this can be an option. Thicker fabrics and blinds can offer a certain amount of noise reduction, but you’ll still hear the garbage trucks and sirens.
