Fireproof House: Top Fire Resistant Building Materials to Consider for Your Home

As the effects of climate change continue, wildfires in the U.S. are steadily rhadamanthine larger and increasingly treasonous than ever. In 2020, wildfires burned 10.1 million acres destroying thousands of homes. The Western U.S. is expressly susceptible to wildfires with cities like Colorado Springs, CO, and Sacramento, CA experiencing a upper risk of fire damage. 

As homeowners in fire-prone states uncork to rebuild, they are sure to wonder whether or not it’s possible to construct a home that will have no issue withstanding flipside wildfire. While it may not be possible to construct a fully fireproof house, there are many variegated precautions you can take to make your home as fire-resistant as possible.

Understand fire rating classifications when towers your fireproof house

First, it’s important to understand fire matriculation ratings and how they work. Fire matriculation ratings are a way of classifying materials by their worthiness to support and propagate fire. They moreover measure how much smoke may be produced by the material, which is unswayable by a flame spread index.

Flame spread tabulate is a value typically obtained by examining how a unrepealable material responds during a ten-minute tunnel test. The flame spread tabulate value is expressed as an wrong-headed numerical value from zero to 100, where a very fire-resistant material has a rating of zero, and a very flammable material has a value of one hundred.

Class A 

A Matriculation A fire rating is the weightier fire rating a material can achieve. Matriculation A fire ratings indicate a flame spread rating somewhere between zero and 25. Materials consisting of brick stone, asbestos-cement board, and rockwool often unzip a matriculation A rating.

Class B

The flame spread rating of Matriculation B would fall between 26 and 75. This rating is typical for slower-burning whole wood materials like cedar, hemlock, or spruce. 

Class C

Class C fire rating has a flame spread rating between 76 and 200. This rating incorporates towers materials like plywood, fiberboard, and hardboard siding panels. It moreover includes any of the faster urgent whole woods such as birch or douglas-fir.

Fire-resistant roofing and siding 

Metal sheeting – Aluminum and steel siding options are virtually unmatched in terms of resilience to environmental hazards. Not only do they withstand rain, wind, hail, and sleet with ease, they’re moreover extremely fire-resistant. Almost all metal sidings receive a matriculation A fire rating and are labeled as noncombustible, meaning that it isn’t shown to ignite or spread fires in fire safety testing.

Fiber glue – As an volitional to vinyl siding, webbing glue is a mixture of cement, sand, and wood fibers. Webbing glue achieves a upper fire resistance with a matriculation A rating.

Fiberglass-based tile shingles – Asphalt shingles make up nearly 80 percent of residential roofing materials in the U.S. They’re one of the most affordable options on the market. With a matriculation A fire rating, fiberglass-based tile shingles are highly fire-resistant when installed with fire-code-compliant underlayments.

Brick and stone veneers – Fire risk is reduced when brick and stone veneers are used over wooden frames. Considering brick and stone don’t have any caulked joints, they can prevent fire from contacting the stud incision and setting fire to the frame of the house. Brick and stone can be used both as roofing and siding with a matriculation A fire rating.

Material Average Cost
Metal sheeting $1.00 – $2.50 / sqft
Fiber cement $5 – $13.50 / sqft
Fiberglass-based tile shingles $1 – $2 / sqft
Brick and stone veneers $5-$10 / sqft

Pro tips: fire-resistant roofing and siding

Choosing a fire-resistant roofing material and using a fire-resistant windbreak underneath will provide peace of mind. Consider using metal or slate tiles, both with a Matriculation A fire rating. These types of materials can forfeit virtually $700-$800 per 100 sq. feet. Shingles are a worldwide roofing material, and the fiberglass-based variety offers spanking-new fire resistance when installed with fire-code-compliant underlayments. The Matriculation A–rated shingle boasts the affordability of tile shingles and financing $50 to $100 per 100 sq. ft. – Pisgah Roofing & Restoration

The first thing we recommend when considering fire-rated applications is DensGlass Sheathing. Exterior Fiberglass Gypsum Wall Sheathing (especially when combined with a fire-resistant exterior material like brick or stone and a fire resistant roof) provides the fire protection homeowners want but moreover protects from moisture and mold. This product works well in warm or unprepossessed climates. – Blythe Towers Company

Fire-resistant decking and framing 

Composite decking – Many home fires uncork on decks considering the majority of wood types used to build decks are rated matriculation C for fire resistance. However, using composite decking materials is a much safer alternative. Composite decking like Ameradeck and Trex are made from PVC and wood webbing giving them a matriculation A fire rating.

Structural insulated panels (SIPs) – These large wall panels can take the place of a conventional stud frame. Their laminated panels are engineered with a solid foam personnel sandwiched between structural sheathing such as oriented strand workbench or plywood. In some cases SIPs are sheathed with webbing glue giving them a matriculation A fire rating, lattermost weather resistance, as well as resistance to mold and water damage.

Aerated touchable – These blocks are made of touchable mixed with aluminum. They are only half the weight of a typical touchable woodcut and provide largest insulation. With whisked touchable blocks you get approximately an hour of protection from flames for every inch of woodcut giving them one of the highest hourly fire-resistance ratings per inch of any towers material.

Fire-retardant treated (FRT) wood – While traditional stick framing is hands flammable it can still be a viable option for your fireproof house if treated with a fire retardant. Fire-retardant lumber has a matriculation A fire rating and is typically misogynist from the same companies that pressure-treat wood. It is an affordable volitional to other fire-resistant framing materials costing approximately $3 for a treated 12-foot 2×4.

Material Average Cost
Composite decking $2 – $3 per linear foot
Structural insulated panels $3.50 – $5 / sqft
Aerated concrete $2.50 – $3 / sqft
Fire-retardant treated wood 25% untreated wood (12 ft 2×4 = $3 avg)

Pro tip: fire-resistant decking and framing

In wildfire-prone territories, homeowners can employ fire-resistant deck towers products to create the ultimate outdoor living scenario. Options like pre-engineered steel deck framing systems unhook proven fire-resistance, strength and performance to support deck functions, while giving play to today’s in-demand rustic, industrial aesthetic. Plus, given the volatility of the lumber market, fire-thwarting alternatives to traditional framing materials don’t push as nonflexible versus a upkeep as they once did. – Fortress Towers Products

Fire-resistant windows and doors 

Double-pane windows – These windows are not engineered to protect versus the heat of a fire and wildfire damage, but they do offer increasingly protection than a single-pane glass window. By vicarial as a barrier, the outer layer of glass slows the heating of the inner pane which helps resist cracking. As far as window framing is concerned, steel provides the highest fire-resistance followed by wood and aluminum.

Steel garage door – Steel makes for an spanking-new fire-proof garage door. Fire-resistant garage doors like Wayne-Dalton’s 9000 series have a personnel made of “polyurethane foam-in-place insulation,” which is a heat-resistant material that immuration to the steel outer panels. These doors often range from $800 to $2,000 depending on size and design.

Steel entry door – Metal entry doors are often recommended by fire prevention specialists to fireproof your home from wildfires. So if your goal is to make the most fireproof house possible, try to use steel entry doors in as many places as you can. Metal doors can offer up to 90 minutes of fire protection to indulge zaftig escape time in the specimen of a fire.

Fire-rated wood doors – If you don’t want to sacrifice the stimulating of a wood door for the fire protection of a metal door, there are a variety of fire-resistant wood doors to segregate from. These doors are synthetic with a personnel that allows for up to 20 minutes of fire protection.

Material Average Cost
Double-pane windows $200
Steel garage door $800 – $2,000
Steel entry door $250
Fire-rated wood doors $800-$900

Pro Tips: fire-resistant windows and doors

Windows must resist the wind-driven debris, and we use metal storm shutters similar to metal fire shutters on the West Coast. No matter where we are on the planet, it seems there is some type of weather event that our structures must survive. Strong materials like steel and touchable are universally the highest quality construction method, permitting our homes to survive fires and storms. – Mark Batson Group

As a unstipulated rule for fire resistant windows, aluminum frames with insulated glass hold up longer when faced with the heat of a wildfire. Consider tempered glass. Variegated types of fire-resistant glass can be used. Glazing thicknesses of up to 60 mm enable a range of variegated uses. The Schüco FireStop ADS 90 FR 90 platform is the understructure for the new concept with 90 minutes of fire resistance. – Sustainable Windows and Doors

Fire-resistant insulation and systems 

Fiberglass – Fiberglass insulation is wontedly used in residential and commercial buildings. It’s created through the weaving of fine strands of glass. Fiberglass is very affordable, widely available, and extremely constructive as home insulation. However, lattermost superintendency is well-considered when installing to stave tiny slivers of glass from rabble-rousing the eyes, skin and plane lungs. While fiberglass isn’t completely fireproof, it can withstand temperatures up to 1,220 degrees.

Reflective insulation – This very popular form of insulation is typically used in between floor studs, roof rafters, and wall joints. Its reflective insulation is designed to reflect heat. Created by bonding a reflective material like aluminum with plastic mucosa or cardboard, it is often used in combination with other forms of insulation to increase its fire-resistance capabilities.

Mineral Wool – There are several types of mineral wool to segregate from including glass, waddle and slag wool. In the U.S., slag wool is the most wontedly used. Although mineral wool can’t stand up to temperatures quite as upper as other options, it is classified as noncombustible and has been shown to reduce fire spread rate.

Foam – Foam cellulose offers much greater resistance to heat than regular cellulose insulation, but may still combust at very upper temperatures. Rigid foam insulation that uses expanded polystyrene is typically preferred due to unrepealable forms of cellulose foam producing gases linked to a variety of health issues. Two of the most wontedly used non-toxic foam choices are  Icynene, a mix of stat dioxide and water, and Air Krete, a solution created by extracting magnesium oxide from seawater.

Material Average Cost
Fiberglass $0.60 – $0.90 / sqft
Reflective insulation $0.35 – $0.75 / sqft
Mineral wool $1.40 – $2.10 / sqft
Foam $0.60 – $0.90 / sqft
