Hotel guests want quiet in their rooms. If they hear traffic or pedestrians or noise from a neighboring restaurant, it’s a negative – and they remember it. Fortunately, there’s an easy way to accomplish hotel soundproofing against outside noise without replacing the windows. Indow window inserts reduce noise coming through single-pane windows by up to 70% and can be installed during a room changeover. The inserts have a patented compression tubing and are custom made to each window opening, allowing it to press into place for an airtight seal, which also provides energy efficiency.
