Mull-It-Over believes that people in glass buildings should not hear their neighbors. White noise devices are not sufficient; a more comprehensive solution is needed. And now there is one!

There's a key six inches of space around the perimeter of every glass building. And no one owned it. Until now.

The Mull-It-Over Mullion Trim Cap design stems from our understanding of building construction. Glass curtain wall facades are popular for bringing natural light into a room while providing many options for shape and color. The main purpose of the curtain wall is to protect the interior of a building from rain, snow and wind. Interior partition walls have been developed to be easy to install and to prevent noise transfer between rooms. The exterior curtain wall was not designed to prevent noise transfer and has been a weak link in the design of all glass buildings.

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 fire rated Mullion Trim Cap option meets UL2079/S115 requirements.
  • 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.
  • The Mull-It-Over Mullion Trim Cap has become the standard design detail for many leading architectural firms.
