Construction Class 6
This Construction Brief will give you an overview of Verisk's Construction Class 6 – fire-resistive construction. When you've completed this course, you will know what a Verisk report means when it says a building is fire-resistive construction. And you'll understand why a particular structure is—or isn't—fire-resistive.
The exterior bearing walls and load-bearing portions of exterior walls must be of noncombustible materials or of masonry, but exterior nonbearing walls and wall panels may be slow burning, combustible, or with no fire-resistance rating.
