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.
1-hour and 2-hour fire rated Mullion Trim Cap options.
FGI Guidelines for Health Care Construction and International Building Code for Multi-Family Housing have minimum STC requirements for demising walls. When tested as an assembly, minimum code requirements will not be met if a demising wall terminates at an exposed mullion.
The Mull-It-Over Mullion Trim Cap is a simple and clean trim detail for the exposed end of a partition wall that allows for differential movement between the partition and glass systems.
Easy to install during new construction or added during retrofit to correct existing sound transfer problems or code violations.
