Common questions about open-cell spray foam
In many cases, yes. Open-cell is an excellent air seal and a great fit for vented attic floors and interior partition walls, where its lower cost and sound-dampening qualities shine. For unvented (conditioned) roof decks, crawl spaces, or moisture-prone areas, closed-cell is usually the better call. We inspect your attic and recommend the right foam for the job.
Very much so. Open-cell's soft, air-filled structure absorbs sound, making it a popular choice for interior walls, ceilings, and media rooms to dampen both airborne noise between rooms and outside sound. If peace and quiet is part of your goal, we can spec open-cell for the acoustically important areas.
