GreenFire Pro Defense for Professionals

Product Overview

GreenFire Pro Defense is designed for use in pretreating homes and buildings to prevent fire damage. Ideal for treating active construction and industrial sites where cellulose-based products and materials are used. Also proven effective at retarding insect attack on treated structures.

Can also be used to treat dry grass and brush in areas surrounding the property to create a defensible space, and to retard the ignition and spread of fire. Unless leached away by a quarter inch or more of precipitation, GreenFire Pro Defense retardant minerals will continue to provide fire protection indefinitely.

Non-toxic, non-carcinogenic, and 100% PFAS free.
