Frame: Buildings with exterior walls, floors, and roof of combustible construction (i.e. wood). Ordinary, Joisted or Brick Joisted (Joisted Masonry): Building with exterior walls of brick, concrete, concrete block or stone.
What is non-combustible construction?
Non-combustible buildings are similar to the fire-resistive type where walls, partitions, columns, floors, and roofs are noncombustible. These buildings typically have a metal floor and metal roof with masonry or tilt-slab walls. They are the least stable in terms of collapse when exposed to fire.
Is stucco a Joisted masonry?
You will have wood walls, brick veneer (single layer for appearance only), stucco, and a wood roof that is not typically anchored. ISO Class 2 is Called Joisted Masonry. Portland cement plaster, or stucco, is made from the same material as mortars, and as such, is sometimes considered to be a masonry product as well.
What is masonry NC?
Masonry is building and fabricating in stone, clay, brick, or concrete block. Masonry also refers to the building units (stone, brick, etc.) themselves.
What is Type 3 construction?
TYPE III – This type of constructed building is also called a brick-and-joist structure by some. It has masonry-bearing walls but the floors, structural framework, and roof are made of wood or other combustible material; for example, a concrete-block building with wood roof and floor trusses.
What are the 4 types of construction?
The four major types of construction include residential building, institutional and commercial building, specialized industrial construction, infrastructure and heavy construction.
Is stucco considered masonry or frame?

What kind of building material is joisted masonry?
The CLM description of joisted masonry construction, followed by the associated ISO construction code, is exterior walls of masonry material (adobe, brick, concrete, gypsum block, hollow concrete block, stone, tile, or similar materials), with combustible floor and roof (Construction Code 2).
What does ISO mean when it says joisted masonry?
When you’ve completed this course, you’ll know what an ISO report means when it says a building is joisted masonry construction. And you’ll understand why a particular structure is—or isn’t—joisted masonry. Buildings with exterior walls of masonry or fire-resistive construction rated for not less than one hour and with combustible floors and roofs.
What are the fire resistance ratings for joisted masonry?
Exterior bearing walls may also be any noncombustible materials with fire-resistance ratings of not less than one hour. There’s one variation on joisted masonry construction that doesn’t change the construction class—heavy timber or mill construction.
What kind of masonry is used for exterior bearing walls?
There are several types of masonry used in the exterior bearing walls of joisted masonry buildings: Note that exterior bearing walls may also be any noncombustible materials with fire-resistance ratings of not less than one hour. Be familiar with the variations of Joisted Masonry Construction.
