6 Fire-Resistant Building Materials To Make Your Property Last

Fire resistant building materials help to maintain the structural integrity of the building during a fire, even to the point that they can outlast the entire structure. Fire resistant materials are often used in high-risk properties, such as schools, skyscrapers, and factories.

Here are six high-quality fire-resistant building materials that can help make your property last.

Multi-Paned Glass Windows

A layer of air is trapped between two panes of glass in a multi-paned window. This air buffer helps stop the spread of fires. If the outer pane of glass breaks, it will break into small pieces that will fall away from the window, preventing the shards from entering the interior space and igniting anything inside.

One example of excellent multi-paned glass window materials is Pyrex. It’s an oven-safe glass, which is able to protect users from fires. The material is strong enough to withstand high temperatures of up to 500 degrees Fahrenheit, so it is safe to use in the oven. It is also non-porous, which prevents it from soaking up the smells and tastes of the foods that are cooked in it.


Concrete is a very durable and strong material and is used in most construction projects. Concrete, combined with fireproofing additives, achieves excellent fire resistance for building properties.

The fireproofing additives that can be added to concrete are:

  • Fire Retardant Additives – that are used to minimize the heat released by the concrete
  • Flame Retardant Additives – that are used to reduce the intensity of heat released
  • Heat Insulating Additives – that are used to reduce the heat transmitted through concrete


Stucco is a plaster made from Portland cement, sand, lime and water. This material prevents fires from spreading by providing a sealant that can withstand heat. Stucco’s sealant allows the building to successfully withstand heat because the sealant makes the outside of the building waterproof.

Stucco also provides a nice surface to apply paint or other finishes to the exterior of the building.


Gypsum is a mineral with a chemical composition of calcium sulfate, which is an alkaline that slows down the oxidation of organic materials.

When applied to a building’s steel-framed structure, the gypsum is heated to a high temperature and then sprayed onto the steel. The heat from the molten gypsum dissolves the steel, which then becomes a permanent part of the building as it cools. This process makes the steel-framed structure fireproof.


Bricks are made out of clay and sand. These materials have a high fire resistance because they both form a protective layer on the surface of the brick, which is why it is said that bricks are made of rock.

Bricks contain a high proportion of clay and sand, both of which protect the surface of the brick from fire.

Spray Polyurethane Foam

The spray polyurethane foam is an excellent fire-resistant building material because it has low burning rates and produces less smoke than other materials. This is caused by the unique properties of the foam which makes it difficult for oxygen to be present.

When the polyurethane foam is applied at a thickness of one inch or more, it acts as a thermal break to slow the transmission of heat. The foam will not melt or drip when exposed to fire at its melting point of approximately 350°F.

Polyurethane foam can also be applied to steel beams and other structural components to protect them from the damaging effects of fire.
