How does a Firezat Fire Shield compare to foam or gels?
Gel and foams can be a big help but they have limitations. When applied by fire professionals just before fire arrival they can be effective. They have the proper pumps, water supply, pressure, and experience to lay down a heavy coat. Most importantly they have access to the property shortly before the fire approaches. Foams hold extra water suspended in bubbles, but under wildfire conditions of wind, heat, and low humidity their effective window is just a few hours at best, after all these are perfect conditions for evaporation. Foams will not protect attic vents or large windows once the foam has dried. If the fire stalls or turns delaying arrival, your foam might be ineffective. While it can be re-hydrated once, with evacuations, road blocks, and municipal water demands it may be impossible to do. And once it’s used you must purchase more for additional fire threats.
