Product Overview
Asphalt saturated kraft building paper has been applied to the lath to control moisture, air flow and reduce air infiltration resulting in improved energy efficiency. Easy to install and ideal as a base for stone, ceramic tile and traditional stucco. The paper backing aids in plaster keying and stucco curing, protection of the sheathing during curing and forms the vertical surface behind the exterior wall cladding (stucco, brick, siding, etc.) that allows moisture to safely drain out of the wall system. It reduces moisture penetration while allowing for the dissipation of moisture vapor from within the structure.
ASTM and Code Standards
The grade D paper typically used is water-resistant, yet highly vapor permeable, and meets federal specification UU-B-790a, type 1, grade D, style 2.
Diamond Lath products meets or exceeds:
• ASTM A653 Standard Specification for Steel Sheet, Zinc-Coated (Galvanized) or Zinc-Iron Alloy-Coated (Galvannealed) by
the Hot-Dip Process.
Paper Specification
• Federal Specification UU-B-790A; Style 1, Grade D, Style 2 which is printed on the paper for easy identification.
