What is the difference between Type 1 and 2 construction?

So, what is Type II construction. The easiest way to define a Type II building is that is has the same structural characteristics as a Type I in that it is non-combustible construction. The major difference is that it is not protected. A Type I building will require a rating of components of two hours or more.

What is a Type 1 construction?

Type 1 structures are constructed of concrete and protected steel (steel coated with a fire-resistant material, most often a concrete mixture), and are designed to hold fire for an extended amount of time in order to keep the fire at bay in the room and/or floor of origin.

What is the most fire-resistant building material?

These are some of the most fire-resistant building materials:

• Concrete. Concrete is highly resistant to heat, and it is noncombustible, so it’s generally considered one of the most effective building materials for slowing down fires.
• Brick. On an individual basis, bricks are extremely resistant to fire.
• Gypsum.

What type of construction is most fire-resistant?

The most fire-resistant buildings, Type 1 structures, are constructed with concrete and protected steel, materials that are able to withstand high temperatures for a long time.
