Which type of materials do not burn, supporting the use of masonry walls in the construction of fire walls?

Masonry materials, such as brick, stone, and concrete, do not burn and are inherently fire-resistant. This characteristic makes them an ideal choice for constructing fire walls, which are designed to restrict the spread of fire between different areas of a building or between adjacent structures. Masonry walls can withstand high temperatures without catching fire or compromising their structural integrity, thus providing a crucial barrier in fire safety.

Other materials, such as wood, fiberglass, and plastic, can ignite and contribute to the spread of fire. Wood is highly flammable, making it unsuitable for fire wall construction. Fiberglass, while it has some fire-resistant properties, may still melt or degrade under intense heat. Plastic materials are also combustible and can release toxic fumes when burned, further compromising safety during a fire event. The non-combustibility of masonry is a fundamental aspect of fire wall design in building construction for enhanced fire protection.
