2 Hour Fire Rating for Curtain Wall!


Adjacent to a building’s interior and integral to the exterior curtain wall is the grid of hollow aluminum tubes that hold the glass in place. And these tubes—six inches of space around the entire perimeter of glass buildings—serve as open air gaps that conduct noise and cannot stop fires. It affects productivity, privacy and safety (including, of course, PIPEDA compliance).

There is now a solution!

Mull It Over acoustic mullion caps were originally designed to complement an acoustically rated demising wall where it meets a curtain wall mullion. The MIO mullion caps can bringing the STC rating of the assembly as high as STC 60. In addition to their acoustic rating the mullion caps are now available with an optional 1 or 2 hour fire rating.
