Firezat Fire Shield Information

How Can a Firezat Fire Shields Help Save My Family Home?

Quick Answers to the Main Questions

Fire Shields provide a fire resistant aluminum barrier which reflects 95% of the radiant heat away from the structure reducing preheating. See new Radiant Heat Test Data. Shields also keep burning embers from lodging on the roof or being drawn into the attic vents and burning the home from the inside out. In addition they protect eaves, a critical fire zone, large glass windows and doors from letting radiant heat in which can ignite furniture and household goods. Remember 80% of the ignitions are caused by radiant heat and firebrands. The 2018 wildfire season is expected to be severe. Structure protection should be planned in advance of the season.

Cover just your roof, just your walls, or the whole house. We strongly recommend covering all exposed surfaces for best protection. Some people will get a couple shields each year and add to their ability to protect until they can cover the whole house. Even if you just cover the roof and facing walls you have greatly increased the chances of your home surviving. Our new 8 X 10 Shields can cover windows and sky lights if you have fire resistant walls and roofs already. Complete Answer Below

Once you spread the shields out you quickly see that using a 750 Sq Ft piece of material covers large areas fast. There is no one way to wrap all houses but it's easier than you might think.

Most structures can be covered in a couple hours by 2 or 3 people with another 40 minutes to an hour to secure the shields for optimum wind resistance. That is about the same amount of time it would take to spray with foam. But once your shields are up your home is protected for days or weeks until you take them down. And your home will be cooler because all that heat is reflected away, a big air conditioner without the power bill. And there is no messy clean up or staining... Just store for the next use.

To cover the roof, just take a roll to the roof and unroll it. Position it where you want it and secure it with sandbags or weights. Secure it with our new Shield Bands for maximum strength and protection.

To cover the walls unroll a shield across the front of the house. Using a staple gun or Shield Band tack one end under the eave and work around the house. Place sandbags or weights on the bottom or use the Shields Bands for maximum strength and wind resistance.

Fire Shields are very affordable when you consider that they can be reused several times a year for many years. Depending on how many you need and how big of an area you are trying to protect they can range from $80 to several thousand dollars. When the cost is amortized over the life of the shields, approx 10 years, the cost can be as low as 1/10th of 1% of the home value.

Firezat has special purchase programs and will be announcing payment plans that will allow you to get the shields now and pay for them over time. Check out the Products page for specials. Please note that during the fire season often the shields will be out of stock so order early.

How Does it work?

Fire Shields Protect in 4 Different Ways

  • Firebrands can travel a 1/2 mile to a mile or more on the winds and be as big as fiery golf balls when they land on your roof
  • This home is a target for fire with a dry shake roof and wood panel siding
  • The dry shakes will catch burning embers and the winds will fan them to flames

First, Fire Shields reflect up to 95% of the fires radiant heat away from your home which prevents it from preheating. A major cause of house ignition is when radiant heat preheats the wood to its flash point, about 585°F. Although wood can burn about 300°F it can burst into flames without flame contact at its flash point. Radiant heat also passes through unprotected windows and preheats curtains, furniture, and carpet to combustion and the home will burn from the inside out.

Second, they provide a fire resistant, slick surface that allows firebrands or burning embers to land and slide off your roof or extinguish safely. They also eliminate sharp angles on your roof that can catch and trap embers allowing them to burn and eventually ignite your roof. Curved tile roofs like those used in the Southwest can become ember-collectors, actually trapping burning embers inside.

Third, fire shields provide a fire resistant layer between your home and radiant heat, flames, and firebrands. By using the water saturation method, simply laying a sprinkler hose at the top of your roof then covering it with fire shields, the shields prevent evaporation and maintain a wet environment under the shields dramatically improving your survival chances. If the heat gets very severe the water will turn to steam, reducing oxygen, wetting fuel (your roof or walls), and dissipates the heat.

And finally, in the worst case scenarios anchored fire shields will deny the fire oxygen that it needs to burn. In some cases after long extended exposure to intense flame or heat some smoldering or charring may occur under the shields. Firefighters can easily extinguish this when they come back after the fire has burned through. Better to replace a section of roof than lose your entire home.

How Much Do I Need?


This varies but is fairly easy to figure out. Firezat strongly recommends covering all areas when possible but if you are planning to stay and defend wrap your home in this order.

Zone 1 is the roof If your roof is not fire proof this is usually the most important area to cover

Zone 2 is the side that will most likely face the fire assault. Many times homeowners know which direction the fire will likely approach from. The east due to Santa Anna wind conditions, or up a slope, or from a dry fuel supply on one side of the structure.

Zone 3 is the rest of the structure

This is one time where more is better so your measurements do not have to be exact.

When measuring or estimating your roof come from the highest point down to the gutter and include enough to cover under the eave and down the wall a foot or so. Eaves are heat traps and critical areas to protect.


To Cover just the roof using the example above = 1800 Sq Ft. times 20% (for overlaps)= 360

  • 1800 + 360= 2160 total sq ft for roof
  • 2160 / 750 (avg size shield)= 2.88 or 3 Fire Shields to cover the roof and eaves.
  • Side Wall #6 W 37' H 9' = 333

It might be helpful to draw a basic diagram of your home and number the walls.

  • Side Wall #1 W 37' H 9' = 333
  • Front Wall #2 W 58' H 10' = 580
  • Front Roof #3 W 15' L 60' = 900
  • Back Roof #4 W 15' L 60' = 900
  • Back Wall #5 W 58' H 10' = 580
  • Side Wall #6 W 37' H 9' = 333

Total Area 3,626 Sq Ft to cover the main panels. We then add 20% for overlaps.


To Cover the entire home 3626 Sq Ft. times 20% = 725

  • 3626 + 725= 4350 total sq ft for home
  • 4350 / 750 = 5.88 or 6 Fire Shields to cover the entire house.
