Mull-It-Over offers a variety of sleek mullion trim caps designed to improve the sound isolation performance where a partition wall meets a window mullion. Without Mull-It-Over, this connection is an acoustically weak path that allows for sound transfer between adjacent rooms. Poor sound isolation can affect productivity, disrupt sleep, erode privacy, and is particularly concerning where HIPAA compliance or confidentiality are required. The Mull-It-Over Mullion Trim Cap is designed to maintain the acoustical performance of the wall without degradation caused by the window mullion.
