Boral Drain-N-Dry Lath

With DELTA®-DRY Technology

A superior lath and best-in-class rainscreen in one product.

Introducing the Boral™ Drain-N-Dry™ Lath, the reinvention of the draining and drying wall system that unifies each critical component into a single, high-performance product—one that requires less fasteners and fewer penetrations. What's more, by seamlessly integrating a chemical and corrosion resistant fiberglass lath, a 10mm rainscreen and a secondary water-resistant barrier into individual 150-square foot, easy-to-cut, lightweight rolls, Boral™ Drain-N-Dry™ Lath actually reduces your installation time to help you quickly deliver a final product that will last the test of time.

  • Installs fast, providing two additional component systems in one pass: rainscreen and lath. Eliminates the need for a secondary layer of Water Resistive Barrier (WRB)
  • Ultimate in moisture management through drainage, drying and moisture vapor control
  • Nothing to rust or corrode and the ultimate in alkaline resistance with integral Alkali Resistant (AR) glass lath
  • A fastener band every 6" ensures solid connection to structure and easy visual inspection of fastener spacing
  • Substantial reduction of fastener penetrations in the primary WRB that typically occur when multiple materials are installed independently
  • Built in self furring feature to ensure proper mortar embedment, and scratch coat thickness
  • Extremely light and easy to transport, move around the job and install from scaffolding
  • Installs with hand driven or pneumatic nails, or staples with no caps or washers needed
  • Cutting and modification is so easy it can be done with a utility knife or scissors
