Celbar RL
Celbar RL, or Celbar Fire and Sound, is a system with one, two,
and three-hour UL rated Firewall Assemblies. One of the most
outstanding features is the record-setting weight load design at
1,415 pounds per stud. These wall assemblies can be constructed
using 2x4 inch or 2x6 inch wood studs. We are proudest of the
sound test results that these three assemblies received with an
STC of 56 with one layer of gypsum board on each side, to the
highest tested STC of 64.

Architects, contractors, and code officials will find this system

affordable, able to meet and exceed all code requirements for
fire and sound control, and easy to install. We have hundreds
of applicators worldwide that have been trained to install our
products.
