FR and FRLS wires are commonly used in residential and commercial buildings, but many people don’t understand the difference.
FR (Flame Retardant) Wires:
These wires prevent the spread of fire.
FRLS (Flame Retardant Low Smoke) Wires:
These wires not only resist fire but also produce very low smoke during burning, making them safer for closed spaces.
For modern buildings, FRLS wires are highly recommended because they improve safety during emergencies.
