born from our original climate seal™ thermal series, the climate seal™ acoustic series storm window insert specifically focuses on sound abatement across all frequency levels with exceptional performance while maintaining its discreet look and superior thermal properties. while the climate seal™ thermal series window inserts abate sound by up to 60% from pre-existing levels, the acoustic series storm window inserts boasts up to 80% sound reduction with an stc rating as high as 49, which rivals or exceeds the performance of many other competitive products and does so at a significantly reduced cost and aesthetic impact.

九线拉王怎么能赢钱the climate seal™ acoustic series model of noise reduction window inserts is an ideal choice for many residential, commercial and historical applications. whether you live on a busy street, airplane flight path or wish to maintain the comfort level of your hotel guests, the climate seal™ acoustic series storm window insert will perform extremely well, regardless of the application. other acoustical window products have you call for a secondary and permanent window layer, which we feel is excessive, bulky and unattractive without an appreciable improvement above and beyond our climate seal™ acoustic series system. the climate seal™ acoustic series storm window insert is easily removed in seconds for access to the primary window for cleaning or maintenance and is just as easily re-applied to protect you from irritating and excessive decibel levels.

below is a comprehensive breakdown of our soundproof window treatment performance ratings and results. we’ve also included a “before & after” scenario on (3) different primary window applications to illustrate how effective the climate seal™ acoustic series soundproof window inserts can be when applied over your primary window. and, just like all of our other climate seal™ family of products, the acoustic series storm window insert is fully customizable. custom paint colors and glazing options, wood veneers as well as custom shapes and sizes are all available to ensure performance and aesthetics are not compromised.
