Sound Proof Glass
Even using just one pane of laminated glass within an insulated glass unit will enhance the noise blocking benefits by several decibels.
Sound proof glass. Benefits of soundproof glass. Soundproof glass while perhaps somewhat of an oxymoron is glass that prevents sound from penetrating from one side to the other. There are a number of different ways to make glass soundproof glass. In most cases people who use this type of glass are those who live near noisy environments such as airports of busy roads.
More cost effective than new replacement windows soundproof glass will act as a sound barrier and eliminate your noise problem without replacing the existing window frames. Such material can block between 90 to 95 of most sounds with only a few frequencies as an exception. One insulated glass unit with 2 pieces of 1 4 laminated glass plus an air cavity and an additional pane of 3 8 laminated glass 6 3 8 aluminum frame acoustically treated frames seals angled flat glass for maximum acoustical performance. This is why laminated glass is commonly used as a type of soundproof glass.
In such cases sound is naturally reduced. The first involves simply making the glass thicker. Solves your noise problems an effective sound barrier. It takes on the mechanical energy of the sound wave and captures it.
