The Best Fire-Resistant Siding to Choose
You should approach building with a fireproofing attitude if you reside somewhere where there is a significant potential for wild or forest fires.
Your protection must start with the building itself, even while drills & emergency evacuation procedures are important to your safety.
The most common siding kinds that are non – combustible or fire-resistant are listed below.
- Vinyl siding
- Wood siding
- Cement and fiber siding
- Metal siding
- Stone and brick siding
- Stucco siding
- Seamless Steel
I will now elaborate on these.
In the US, vinyl siding is the most often used material for residential dwellings. This is due to the fact that it is the most prevalent form and often the least expensive. It will also look wonderful on almost any house and is likely to endure for many years.
The drawback is that it’s one of the least fire-resistant forms of home siding. For homeowners who reside in a wildfire-prone location, it is normally not advised. Because vinyl is constructed of synthetic plastic, it rapidly melts when exposed to high temperatures.
Your home’s inside walls become visible due to melted vinyl, which might further damage it. In fact, if your house is in high fire danger, the Federal Emergency Management Agency does not advise putting vinyl.
But if you’d rather install vinyl, you may increase its fire resistance by putting 5/8-inch-thick gypsum boards underneath the siding and taping their connections. If the vinyl melts, that will assist preserve a little amount of protection.
When you hear wood, you may assume that it is particularly combustible. Wood siding is distinct from firewood, even if that could be the case.
There are many methods to increase its fire resistance, such as coating wood surfaces with flame retardants to limit the spread of the flames. Sprays made of chemical flame retardants aid in enhancing this home siding material’s fire resistance.
Wood siding is still more prone to burning in a fire than other forms of siding that are more fire-resistant, despite the fact that it does assist to increase the resistance. Remember that the siding assembly’s seams might still allow the fire to enter your home’s stud cavity.
The roof soffit or external trim may not be safe even if you may have treated your siding. A separate, treated, or fire-resistant trim should also be installed.
But there are many additional reasons why wood siding is a fantastic option. It is good for energy efficiency and has beautiful natural features. It aids in keeping your house warm in the winter and cool in the summer.
Cement and fiber siding
Particularly when compared to other forms, fiber cement siding has a very high fire rating. Sand, concrete, and wood fibers are the main ingredients of this vinyl substitute. Without losing toughness and usability, it obtains a high fire-resistance rating.
Numerous fiber cement products have a class A fire rating, meaning they can endure intense heat for an extended period of time before melting.
In an emergency, they may also delay the spread of flames, preventing surrounding structures from being damaged and giving the fire agencies more time to get to your home.
James Hardie fiber cement siding is among the most popular varieties among homeowners in the U.s, despite being normally more costly than conventional siding types like vinyl.
Products from James Hardie blend excellent performance with exquisite aesthetics. The business is renowned for having better durability & curb appeal than its rivals.
Metal siding can be your best option if you reside in a wildfire-prone location. It almost resists fire, in fact. When environmental threats arise, aluminum and steel exteriors are the best choice since they can withstand rain, sleet, snow, & hail.
The majority of metal siding varieties are classified as noncombustible, which indicates that no evidence has been discovered that they may catch fire and spread.
Despite the fact that metal siding is often more economical than vinyl, it is still more costly. When choosing your siding, you must take it into account. Due to its fire resistance, many people believe that it is more than worth the additional expense.
Stone and brick siding
Other forms of fire-resistant home siding materials include brick and stone. Brick has a reputation for being fire-resistant. Since it doesn’t have caulked seams, it could also aid in keeping flames away from the rest of your home.
Many fires start when flames penetrate the siding and catch fire to your home’s more flammable interior wall components. One less thing to worry about is if your siding can stop the flames from spreading in the first place.
Although brick or stone veneers are often more costly than vinyl, many homeowners choose them because of their increased durability and fire resistance.
What is the stucco’s fire resistance? Exteriors with a traditional or stucco look are well renowned for being very fire resistant.
When built correctly, this kind of plastic siding has a one-hour fire rating, giving homeowners up to an hour before the material succumbs to the heat of the fire and starts to spread. Firefighters will have enough time to reach residents in stucco homes as a result.
Because of its strength, seamless steel can withstand shrinking and bulging that may be brought on by rapid temperature fluctuations. You may have seamless steel fabricated specifically to meet your home’s dimensions.
To replicate the organic appearance of wood, you may even get seamless steel siding with a wood-look texture.
Additionally, you may think about putting corrugated steel, which is often used in prefabricated military buildings and industries. Corrugated steel may thus be seen as more of an industrial product than material for residential siding. The advantage of this material is that it can withstand extreme weather pretty well.
The one significant drawback of steel is that it requires a lot of work, which might result in greater labor expenses and a costly project.
Which Siding Material Is The Worst?
Aluminum and vinyl are the worst to use as a siding material.
A siding’s main purposes are to provide the home with strong curb appeal and shield it from the weather. A siding that cannot provide these advantages to a homeowner is, therefore, poor siding.
Aluminum might be regarded as a siding material that is not recommended for installation in your house based on the information provided in this article.
This is due to the ease with which metal may be damaged, leaving unsightly blotches. It may also sustain dents & damage from severe weather, including hail.
Vinyl is another substance that should not be used for siding. Extreme weather conditions might quickly harm it. After being used for a while, it may also start to fade, fracture, or melt. Regarding ecology, there is much debate concerning how vinyl is made.
In fact, several research indicates that vinyl is not eco-friendly. Although vinyl may be recycled, the process of making it is thought to be particularly harmful to the environment.
You want to be sure that you choose carefully and intelligently since the materials stated above each have their own advantages and disadvantages. This is due to the fact that although appearances may be fairly alluring, endurance is the quality that really has to stand out.
You want a material that looks excellent and is also adaptable, water-resistant, and simple to install. You may want to ask professionals for guidance on the best siding material if you are still undecided.
Which kind of siding need to be avoided?
Avoid flammable things as much as you can if you live in a fire-prone location. Wood and the wildly popular vinyl siding are examples of this.
As you may know, vinyl is comprised of plastic, which melts & spreads when it catches fire, as opposed to wood siding, which is inherently combustible.
However, if you’re set on putting wood siding, you may spray the material with flame-retardant chemicals to improve its fire resistance. However, keep in mind that fire may still spread via the roof or through inner cavities, so you might wish to fireproof such areas as well.
Regarding vinyl siding, considering how inexpensive it is, it could be tempting to use it despite the dangers. Add gypsum board between the house wrap & siding to strengthen the material’s fire resistance.
Once the vinyl melts, it will serve as a temporary barrier to prevent the fire from spreading inside your house.

- Keep flammable substances like kerosene and gasoline in a shed outside of your house.
- Lastly, check to see whether there is a clear path to the fire escape.
- That’s all, then! Always select siding carefully since prevention is always preferable to treatment!
