Mull-It-Over Products provides sound solutions for glass buildings with the simple, yet well-designed, Mull-It-Over Mullion Trim Cap.

The Mull-It-Over Mullion Trim Cap provides the coordinated transition between interior and exterior systems so they perform to their full potential. Noise transfer between rooms is no longer a problem.

Building code requirements, confidentiality, privacy, productivity and HIPAA compliance for buildings with glass facades now have a simple design solution. A standard mullion has an STC rating of 28. If left exposed, sound transfer between rooms will be a problem due to the poor noise deadening performance of the mullion.

The Mull-It-Over Mullion Trim Cap increases the STC rating at the mullion to minimize sound flanking. The product is easy to install during new construction or to add during retrofit, to correct existing sound transfer problems or code violations.

The Mull-It-Over Mullion Trim Cap is manufactured in the USA and has become the standard design detail for many leading architectural firms.
