Fire can break out anytime, especially in unprepared residential areas, where small flames can turn into a disaster within minutes. Electrical problems, cooking mishaps, and malfunctioning appliances can ignite a fire, swiftly engulfing unprepared homes.
Choosing fire-resistant materials is essential, especially in residential building construction. From roofs to walls, doing so is one of the smartest and most effective ways to protect your family and your property from unprecedented disasters. Fire-resistant materials not only slow down the spread of fires, but they can significantly prevent massive damages and loss.
In this article, we will discuss why choosing fire-resistant materials matters in home fire safety and prevention.
Why Fire-Resistant Homes and Buildings Matter
While prevention is key, protection matters too.
When a fire breaks out, fire-resistant materials serve as the initial line of defense. Instead of instantly catching fire and fueling the flames, these materials can delay or even prevent the fire from spreading. That extra time is crucial for firefighters to respond and for residents to evacuate safely.
Aside from saving lives, fire-resistant homes also protect neighboring properties. In tightly packed communities, one burning house can quickly set off a chain reaction, putting an entire street at risk. Fire-resistant materials help break that cycle.
Fire-Resistant Roofing Materials and Their Benefits
Roofs are one of the most vulnerable parts of a house when it comes to fire. Sparks, embers, or even debris from nearby fires can land on a roof and burn. This is precisely why selecting the appropriate roofing material is crucial for ensuring fire safety in homes.
Here are some of the best fire-resistant materials you can use for your roof:
1. Metal Roofing
Metal is non-combustible, making it one of the best choices for fire resistance. It’s also durable, lightweight, and widely available in the Philippines.
However, while metal roofs themselves don’t combust, the structural steel used in their construction can lose strength when exposed to high temperatures. Therefore, ensuring proper insulation and fireproofing measures is crucial to maintaining the overall integrity of the structure during a fire.
2. Clay and Concrete Tiles
Clay and concrete roofing tiles are naturally fire-resistant and non-combustible, achieving a Class A fire rating when installed over a non-combustible roof deck—the highest level of fire resistance. They also last a long time and add a stylish look to homes.
However, it’s important to note that while the tiles are fire-resistant, the overall effectiveness depends on proper installation and maintenance. For instance, damaged or missing tiles can create vulnerabilities where windblown embers might penetrate, potentially compromising the roof’s fire-resistant properties.
3. Slate Roofing
Slate is a tough, fireproof natural stone roofing option, but it’s also heavier and pricier than other materials.
A slate roof can weigh anywhere from 800 to 1,500 pounds per 100 square feet—way more than asphalt shingles, which come in at just 230 to 430 pounds for the same area. As for the cost, installing a slate roof on a standard 3,000-square-foot home can go over a million pesos, with natural slate tiles priced at around ₱900 per square foot.
4. Fiber Cement Shingles
A mix of cement and fibers, this roofing type is fire-retardant while also being lightweight and easy to install. Some products have a fiber cement siding that has a Class A fire rating when tested in accordance with ASTM E84, with a flame spread index of zero (0).
5. Gypsum Board
Gypsum board, commonly known as drywall, is a popular material for interior walls and ceilings due to its fire-resistant properties. When exposed to heat or fire, gypsum undergoes a process called calcination, where it releases water vapor. This endothermic reaction absorbs heat, thereby slowing down the spread of fire.
Specialized types of gypsum board, such as Type X and Type C, are designed with additional fire-resistant features.
- Type X incorporates glass fibers to reinforce the core, reducing the size of cracks during exposure to fire and extending its resistance time.
- Type C goes a step further by adding vermiculite, which expands when heated, maintaining the board’s structural integrity during fire exposure.
Where to Buy and How to Install Fire-Resistant Roofing
Many hardware stores and construction suppliers in the Philippines offer fire-resistant roofing and wall materials. Popular options include:
- Wilcon Depot—A leading home improvement and construction supply store offering various fire-resistant materials.
- CW Home Depot—Provides a wide range of building materials, including fire-rated products.
- Ace Hardware—Carries fire-resistant materials and other construction essentials for home improvement and safety.
It’s always best to ask for fire-rated materials and check for certifications before making a purchase.
Fire Safety Regulations and Compliance in the Philippines
The National Building Code of the Philippines (NBCP) sets fire safety regulations to minimize fire risks in residential and commercial buildings. These rules define fire-resistant materials, construction techniques, and building design requirements to improve fire protection.
Key Fire Safety Provisions in the NBCP:
- Fire-Resistant Exterior Walls (Section 704): Exterior walls must have fire-resistant properties and opening protection, depending on their distance from the property line. If openings like windows are required to be fire-protected, they cannot exceed 50% of the total wall area per story.
- Fire-Resistive Construction for Stairs and Exits (Section 1207): Interior stairways must be built according to fire-resistive standards. Any enclosed space beneath the stairs must have one-hour fire-resistive construction to prevent fire from spreading.
- Fire-Resistive Ratings for Materials (Sections 601-603): Fire-resistant materials are classified based on their ability to withstand fire.
- Fire-Resistive Regulations (Section 604): The Department of Public Works and Highways (DPWH) is responsible for setting testing standards and regulations for:
- Fire-resistant construction materials
- Fire doors, windows, and protective openings
- Smoke and fire detectors
- Fire-retardant roof coverings
- Fire-resistant walls, partitions, ceilings, and structural members
The NBCP enforces fire safety measures to protect lives and property. Homeowners, builders, and developers must follow these regulations when selecting materials and designing structures. Failure to comply may lead to penalties, fines, or suspension of building permits.
Always check with local authorities and ensure that contractors follow fire safety guidelines for long-term protection.
Fire Prevention Starts with Smart Choices
Fire safety isn’t just about having a fire extinguisher or smoke detector—it starts with the materials used to build your home. Choosing fire-resistant roofing and walls can make a huge difference in preventing disasters and keeping your family safe.
For homeowners and developers, investing in fire-resistant materials is a responsibility. Ensuring that homes follow safety regulations and use the right materials can help prevent tragedies before they happen.
Staying safe from fire starts with making the right decisions today. Don’t wait until it’s too late—choose fire-resistant materials and build a safer home for everyone.
