Question: 1 / 400

When using metal lath for SFRM application, what is the minimum required weight?

1.0 Ib/cubic yard

1.5 Ib/cubic yard

1.7 Ib/cubic yard

The correct choice reflects the minimum weight requirement necessary for metal lath used in the application of Spray-Applied Fire-Resistive Materials (SFRM). The specified minimum weight of 1.7 pounds per cubic yard ensures that the metal lath provides adequate structural support and stability for the fireproofing material. This weight is important because it affects the overall performance of the fire resistance system, ensuring it adheres properly and maintains its integrity under fire conditions. A weight lower than this could compromise the installation, leading to issues such as insufficient support or detachment of the fire-resistive material, which would inhibit its effectiveness in protecting the underlying structure during a fire event.
