Celbar RL Two Hour Firewall
Sound control, fire safety
The new Celbar RL system leads the industry with our new one to three hour fire and sound rated assemblies. One of the most outstanding features is the record setting weight load design, which is 1415 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. They were a 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 licensed applicators nation and worldwide that have been trained to install our products.
Celbar RL cellulose insulation is eligible for use in the UL Design Nos. |
