PrivacyShield® Window Seal Kit Quite often we get calls about soundproofing a window. Our customers have issues with sound from traffic & highway noise, neighbors, barking dogs, HVAC and other machinery, etc. coming into a residential or commercial space. Typically, the compliant is that sound is coming in through the existing windows. Soundproofing a window helps provide to reduce distracting noise.

So, how do I go about window soundproofing? Below I will outline some ways to block sound from entering an interior window.

OPTION 1: Replace Existing Windows with Soundproof Windows

Soundproof windows will typically have multiple layers of glass with air gaps in between. Milgard and other suppliers carry soundproof lines that can replace your existing windows.

  • PROS: Effective, aesthetically pleasing solution.
  • CONS: Expensive and may require a contractor to install.

Option 2: Soundproof a Window with a Window Seal Kit

The PrivacyShield® Window Seal Kit easily installs over the existing windows. These magnetically mount to the surface of the window trim or install in between the jambs of the window. The kit provides both acoustic and thermal insulation and is removable for access for cleaning or maintenance. The PrivacyShield® Window Seal Kit is compatible with a wide range of window styles.

  • PROS: Inexpensive add on. Easy to remove and you get to keep your existing window style. Reduces noise and lowers heating & cooling costs.
  • CONS: Not having one installed on your window yet!

Option 3: Soundproof a Window with Clear Sound Barrier

A custom sized window panel can be created using our AudioSeal® Clear Sound Barrier. The barrier can be manufactured in a size up to 48″ wide. The clear vinyl panel is then applied using Velcro to the perimeter frame of the window. The clear barrier panel will need to extend past the visible glass and adhere to the perimeter molding to create a good seal and air gap. This option may not work with all styles of windows. See illustrations to the right.

Option 4: Soundproof a Window with a Barrier Blanket

The ABSC25 Sound Combination Blankets is typically manufactured with grommets for hanging and velcro on the vertical edges. This allows blankets to hang temporarily over a window or opening. These can be sized up to 48″ inches by 25′ (some limitations may apply). It may take multiple blankets to cover larger windows. Blankets may be made to overlap with mating Velcro, allowing for a good sound seal and to hold the blanket in place. The blanket panel will need to extend past the visible glass or window frame and adhere to the perimeter molding to create to seal any potential air gaps.
