Fire-Resistant Building Materials for Safer Homes

Concrete 

Concrete is widely used in most building projects. It doesn’t catch fire easily and doesn’t transfer heat in extreme conditions. Since it’s dense, it acts as a barrier between building compartments, making it difficult for fire to spread. 

Though concrete is fire-resistant, its ability to withstand high temperatures depends on the quality of the materials that make it up. High-quality concrete can withstand heat over 950°C before it begins to break down. 

Brick

Brick is a good fire-resistant building material. It is made by shaping clay, letting it dry, and then firing it in a kiln, which makes it adapt and resist high temperatures. The fire resistance of brick is strongest when it stands as a single unit. 

When bricks are connected together to form a wall, the mortar used in between reduces their ability to withstand fire. Even then, brick is still an ideal fire-resistant material.

Insulated Concrete Foam

Insulated concrete form is made by pouring reinforced concrete into insulating foam panels, which are usually made of polystyrene. This form of concrete is more fire-resistant and also looks better. ICF can resist severe fire outbreaks for three hours or even more. 

Gypsum Board 

Gypsum board is a reliable fire-resistant building material made of gypsum enclosed between two sheets of paper. It is also called drywall and resists fire through a mechanism that’s slightly different from the rest. 

Gypsum board has water molecules within it, and in the case of a fire outbreak, the water turns into vapor and cools the surrounding area, reducing the spread of fire. After the water has been completely used up, the gypsum core continues to resist fire for some time before weakening. Using multiple layers of gypsum boards makes it more fire-resistant.

You can make your drywall more fire-resistant by applying a fire-resistant spray over it. 

Steel 

Steel is an alloy that’s well known for its non-combustible nature. It can withstand fire outbreaks for a long time, but it’s also vulnerable to melting at very high temperatures. Steel is usually used to reinforce concrete as an internal structure. It has high tensile strength and doesn’t rust or get attacked by termites.

When using steel in construction, apply intumescent paint to make it more fire-resistant. 

Dual-Paned Glass

As the name suggests, dual-paned glass is made up of two pieces of glass, one placed opposite the other. It is better than ordinary glass because it takes twice as long to shatter. Glass is naturally prone to shattering when exposed to heat and fire, but with dual-paned glass, the outer layer shatters first, protecting the inner layer for longer. 

Tempered Glass

This glass is relatively stronger than dual-paned glass because of its thermal and chemical treatment. It can resist fire outbreaks for at least four hours, making it ideal for buildings in areas prone to fire attacks. We recommend installing it between the panes of dual-paned glass for the best results.

Tempered glass helps contain fire and smoke within compartments, reducing how far and fast fire spreads inside a building.

Wired Glass

This is the best glass option among the rest, as it contains wire mesh. It reduces the chances of glass getting shattered during a fire outbreak and helps prevent fire from spreading to other compartments of a building. 

However, being the most ideal option doesn’t make it suitable for every part of a building because the wire mesh in it limits visibility. 

Stucco

Stucco is a coating or plaster made from cement, sand, lime, and water. Besides being a great interior and exterior wall finish, it’s also well-known for its fire-resistant properties. It doesn’t ignite and helps slow the spread of fire, giving you enough time to safely exit the building. 

Stucco can resist fire for about an hour, which is significantly more than other materials like vinyl. 

Synthetic Roofing Materials

Using fire-resistant materials isn’t just important for floors, doors, windows, or walls. The roof also plays a huge role. Fire-resistant roofing materials like metal and concrete help prevent sudden flare-ups and contain the fire from spreading to other parts of the building.

You can apply intumescent coating to your roof to make it more fire-resistant. 

Tips to Use Fire-Resistant Building Materials

Whether you’re looking to start a fresh building project or work on an existing building structure, here’s how you can use fire-resistant building materials for a safer home.

• Seek advice from an expert: Homeowners who want to use fire-resistant building materials often have little to no knowledge about what types are ideal for their building structure. Consult and seek advice from construction experts to choose the right materials.
• Confirm certification for fire-resistant building materials: Internationally, an ISO certificate is given to fire-resistant materials that have been tested and rated. Confirm the certification for every building material you purchase.
• Hire a professional for installation: If you’re building from scratch, fire-resistant materials should be included in the architectural design and installed by professionals. It’s also best to hire professionals for existing building structures.
