Types of Soundproofing

First, a disclaimer: you can’t completely soundproof a space as long as there is air. Anywhere air goes, sound goes too. Check for air quality solutions while adding soundproofing to a space.

There are two main types of soundproofing:

Sound reduction, which stops sound from entering a space. Sound reduction will help keep your space free of outside noises such as weather, outdoor conversations, and traffic.

Sound absorption, which stops sound already inside a space from echoing and reverberating.

How Our Window Inserts Work
Soundproof window inserts fit onto existing windows to air seal. They are made from high-grade acrylic to both reduce and absorb sound.

Our Standard Grade inserts block sound by 50% and our Acoustic Grade inserts block more than 70% when placed over operable single-pane windows. When placed over operable double-panes, Acoustic Grade inserts reduce noise by up to 12 dBA – that’s more than a 50% reduction in noise and an STC rating of 42 to 45.
