Vermiculite spray can be used to enclose ductwork to maintain an FRL of up to 3 hours. All of our passive fire spray work is carried out by trained applicators to guarantee a smooth finish and a clean worksite. We can also install fire rated fan unit enclosures and fire rated access panels. All of our work comes complete with identification and compliance certification.
Fyrewrap and similar products can be used as an alternative to vermiculite spray for protecting a duct. Fyrewrap offers a clean, easy, and fast approach to duct fire protection and can be up to four times lighter than fire spray. It can also be used to achieve fire rated fan units with fire rated access panels.
