The system can be controlled by a simple on/off switch,or it can be fully automatic(snow melt detector)
Building codes
GFRC is covered in Section 1903.11 of the Uniform Building Code and in
ICBO’s Evaluation Report ER-4359, Section 1406.3 of the National
Building Code, Section 1910 of the Standard Building Code, and Table
719.1 (2) items 15-1.10 and 15-1.11 of the International Building Codes.
Fire Endurance
GFRC made of cement, glass fibers, sand and water is non-combustible
and meets the requirements of ASTM E136. When used as a surface
material, its flame spread is zero. In addition, tests for
non-combustibility, ignitibility, and fire propagation have been
conducted in England in accordance with the appropriate British
Standard on “Fire Tests on Building Materials and Structures”. BS 476.
GFRC made with polymer curing admixtures will meet the requirements of NFPA Class A and UBC Class I when tested according to ASTM E84, resulting in a “0” Flame Spread Rating and less than 5 smoke density.
GFRC can be designed to provide one and two hour fire rating. The rating is defined in ASTM E119.
