The Problem: Noisy Glass Buildings
Glass buildings can be beautiful, but they often have noise problems. Gaps in the mullions can let sound leak through, reducing a building’s ability to block out unwanted noise.
The Solution: Mull-It-Over®
Mull-It-Over® Mullion Trim Caps are designed to fix this problem by improving sound insulation in glass buildings. Keep reading to find out more about how Mull-It-Over can help you create a quieter indoor environment.
Understanding Mullions and Sound Transmission
What are Mullions?
Mullions are those vertical aluminum tubes that hold the glass in curtain wall systems. They’re structural components, but they can also be weak spots when it comes to sound.
Gaps in standard mullions let sound pass right through, which lowers the wall’s overall STC (Sound Transmission Class) rating.
The STC Rating
STC, or Sound Transmission Class, is a rating that tells you how good something is at blocking airborne sound. A standard mullion usually has an STC rating of around 28, which isn’t great for sound insulation.
Mull-It-Over® Mullion Trim Caps: Features and Benefits
Mull-It-Over® Mullion Trim Caps offer some unique features that can make a big difference in your next construction project.
Soundproofing Capabilities
Mull-It-Over® caps can significantly increase the Sound Transmission Class (STC) rating of the mullion, which reduces sound flanking. Options for STC 55 and STC 60 are available. The caps have an extruded aluminum surface and an interior made of upcycled expanding foam.
Installation and Compatibility
These caps are designed to be easy to install, whether you’re working on a new building or a retrofit project. They’re also compatible with most curtain wall systems.
