PrivacyShield® Speech Privacy Without the Noise!

Our PrivacyShield® Window Seal Kit is the perfect solution to provide a thermal and acoustic sound seal to existing windows. This acoustical window insert specifically focuses on sound abatement across all frequency levels with exceptional performance while maintaining its discreet look and superior thermal properties. The PrivacyShield® Window Seal boasts up to 80% sound reduction with an STC rating as high as 49. This rivals or exceeds the performance of other competitive products at a significantly reduced cost.

The PrivacyShield® Window Seal Kit is an ideal choice for residential, commercial or any application requiring sound and noise control. Whether you live on a busy street, airplane flight path or wish to maintain the comfort level of your hotel guests, the PrivacyShield® Window Seal Kit window insert will perform extremely well, regardless of the application. Soundproofing your windows has never been easier. In addition to reducing exterior noise, these acoustic window seals also provide thermal insulation, saving money on heating and cooling.

The seal mounts on the interior side of the window. Since the seal is installed using a magnetic mount, the PrivacyShield® window insert easily removes in seconds. This allows for access to the primary window for cleaning or maintenance.  The acoustic seal is just as easily re-applied to protect you from irritating and excessive decibel levels. The window seal frames are available in white and brown. Other custom options include acrylic glazing and custom shapes.

Cleaning and Maintenance:

PrivacyShield® Window Seal Kit may be washed with mild dish washing liquid mixed with lukewarm water. It is strongly recommended that anti-static cleaner/polish solutions be used.

  • Use a soft cloth or chamois (we recommend WypAll®) and as much solution as possible.
  • It is recommended that you wipe in a vertical and horizontal direction. Try not to wipe in a circular motion, because should there be any grit on the acrylic, you will be running it over the surface many times.
  • Always wipe and polish until completely dry and the surface feels as “smooth as ice”.
  • DO NOT use paper towels because they are naturally abrasive.
  • DO NOT use ammonia-based cleaning fluids (such as WINDEX), scouring compounds, gritty cloths, leaded or ethyl gasoline, or strong solvents such as alcohol, acetone, carbon tetra chloride, etc.
  • To remove minor scratches, apply a thin coat of a good grade of automobile paste wax (not a cleaner/wax combination) with a soft, clean cloth to protect the surface of the acrylic sheet and maintain its luster.
  • To remove grease, tar or paint, use good quality naphtha.

Storing when not in use

It is preferable that the windows be inserted in poly bags and stored horizontally on their side. This helps prevent scratching from dirt particles that may be present on the surface when the windows are stored flat. In storing horizontally on its side, you ensure the PrivacyShield® Window Seal will maintain its original shape, as it is a flexible product.
