Type II Construction: Non-Combustible
They typically contain metal floors and metal roofs with masonry or tilt-slab walls. Newer school buildings, shopping malls, and recently renovated commercial structures typically fall under this construction type.
What is non-combustible construction material?
• Non-combustible means that the material will not ignite, burn or release flammable vapors. when exposed to fire or heat. Examples of non-combustible materials include steel, masonry, ceramics and certain insulating materials (such as fiberglass or mineral wool insulation).
What is considered a non-combustible building?
Type II: Non-Combustible
Similar to Type I buildings, the building materials of Type II construction projects, including interior walls, framing, floors, roofing, and exteriors, are all made of non-combustible materials such as metal and concrete.
Does non-combustible construction mean that it is fire proof?
Most non-combustible materials have a Class A flame spread rating allowing them to be used for walls and ceilings in a building. Fire sprinkler protection often allows the flame spread rating to be reduced by one class. Fireproof is an old, outdated term that was intended to denote that something would not burn.
What are the 2 major types of construction that are considered non combustible?
Type 1: Fire-resistive: High-rise buildings made of concrete and protected steel. Type 2: Non-combustible: Newer buildings with tilt-slab or reinforced masonry walls and a metal roof.
What is the least fire resistant construction type?
Type 5 structures
The most fire-resistant buildings, Type 1 structures, are constructed with concrete and protected steel, which can withstand high temperatures without collapsing. By contrast, Type 5 structures, the least fire-resistant, are lightweight and made of combustible materials that collapse soon after catching fire.
