Soundproofing a Window

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 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.

• PROS: Inexpensive and removable. Allows light to pass through.
• CONS: May not achieve a specific desired look.

OPTION 4: Soundproof A Window With A Barrier Blanket

The PrivacyShield^® Dual-Sided Absorptive Soundproofing Blanket 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.

• PROS: Removable / temporary solution. Blocks & absorbs sound.
• CONS: Loss of light / vision and use of the window.
