There's a key six inches of space around the perimeter of every glass building. A transition space that was poorly detailed. Until Now. The Mull-It-Over Mullion Cap stems from our understanding of buidling construction. Adjacent to a building's interior and integral to the exterior curtain wall is a grid of hollow aluminum tubes that hold the glass in place. And these tubes serve as open air gaps that conduct noise and cannot stop fires. If affects productivity, privacy and safety. White noise devices aren't sufficient and a more comprehensive solution is needed. Mull-It-Over provides the solution.
