ISOLATEK® 3.4 Galvanized Lath

Quick Resources

ISOLATEK 3.4 Galvanized Lath is manufactured from prime quality steel sheets that are slit and expanded to form small diamond shaped openings. The large number of openings provide a superior substrate for the bonding of CAFCO® FENDOLITE® M-II, TG, and M-II/P / ISOLATEK Type M-II, TG, and M-II/P cement based fireproofing materials. All sheets are flat 27” x 97” rectangles with square ends and smooth parallel edges on the sides for fast easy handling. Sheets are rigid yet bendable for both box and contour designs.


  • Used as mechanical reinforcement for ISOLATEK SFRMs.
  • Small diamond shaped openings conserve fireproofing and reduce waste.
  • Minimizes stress cracks by maintaining consistent material depths.
  • Excellent for boxed and contour designs.
  • Available in 3.4 pounds per square yard.
  • Meets Specifications ASTM C846, ASTM C1063 and ASTM A653.
