UPDATE: Fire and Sound Manual Released
New Fire and Sound Manual released to increase ease of access by architects.
The Fire and Sound Manual
When designing UL assemblies, it’s important to maintain a balance between acoustic isolation and fire protection. Both are essential for safety and comfort. Our designs all conform to the limits specified in the UL Design. This includes variables like insulation thickness, where and how it’s placed in the cavity, and resilient channel spacing, and much more.
