Single-frame partitions on Siniat's Resilient Acoustic Stud for higher sound insulation without going to a twin frame. Max height is Siniat's EN fire-state height (the figure Siniat say to use unless otherwise specified); the cold-state (mechanical, L/240 at 200Pa) height is shown alongside. Use the filter to narrow by performance or board.
