Construction Class 1
This Construction Brief will give you an overview of Verisk Construction Class 1 – frame construction. When you've completed this course, you'll know what a Verisk report means when it says a building is frame construction. And you'll understand why a particular structure is—or isn't—frame.
Buildings with exterior walls, floors, and roofs of combustible construction—or buildings with exterior walls of noncombustible or slow-burning construction with combustible floors and roofs. Frame buildings generally have roofs, floors, and supports of combustible materials, usually wood, and combustible interior walls.
Two variations on frame construction don't change the construction class:
Masonry veneer is thin layers of brick, stone, or stucco, used for appearance purposes rather than structural support.
A building with a metal exterior wall may not look like frame construction, but when the metal skin is attached to wood studs and joists, Verisk classifies the building as frame.
The load-bearing portion of the exterior walls and the roof supports are wood.
