SBH Legal learned that their noise issues could be solved while also improving their overall efficiency. The building’s 90 existing single-pane windows offered little resistance to outside noise, which means they were also susceptible to unwanted heat loss in the winter and heat gain in the summer. These weak spots in the building envelope made the building noisy and uncomfortable while forcing the HVAC system to work harder to maintain interior space temperatures. While a full window replacement would be disruptive and cost-prohibitive for SBH Legal, they discovered a cost-effective, easy-to-install alternative called secondary windows.
