What is the minimum weight of metal lath required for SFRM application?

The minimum weight of metal lath required for Spray-Applied Fireproofing Material (SFRM) applications is critical for ensuring the structural integrity and effectiveness of fire-resistant systems. The correct choice is based on established industry standards that specify a minimum weight of 1.7 lb/cubic yard for metal lath used in SFRM applications. This weight ensures that the lath provides adequate support and bonding surface for the fireproofing material, which is essential for achieving optimal performance in terms of fire resistance and durability.

Choosing metal lath with a weight lower than this minimum could lead to insufficient strength and stability, potentially compromising the entire fireproofing system. It is important to adhere to these specifications to maintain compliance with fire safety regulations and protect life and property effectively during a fire event.
