How much does soundproof glass cost?
Soundproof glass, also called acoustic glass or soundproof glazing, isn’t cheap and varies in cost depending on the specifications. However, you can expect to spend around $950 for a double-pane laminated glass window, plus the labor needed to install it. In contrast, soundproof polycarbonate panels like DefenseLite typically cost about $30-$75 per square foot to install. All DefenseLite panels are installed by trained and certified dealers and are covered under manufacturer warranty. Depending on the system, warranties range from a minimum of 2 years to up to 15 years.
