Structa Wire Energy Efficiency Systems

Structa Wire Energy Efficiency Systems

Increasing standards for energy use mean that architects and builders need to detail stucco walls that are both economical and energy efficient. Structa product options assist in delivering these energy-saving building solutions. In addition, all our products are manufactured from recycled steel, contributing to LEED points. Whether the wall meets the required higher standards through more cavity insulation or by attaching continuous insulation on the exterior, our products allow for wall configurations that ensure a high-performing, energy-efficient stucco system.

MEGA LATH VERTICAL INSTALLATION ON STEEL FRAME:

This wall system has been used successfully to meet increased thermal ratings required by new energy codes. Mega Lath, installed vertically, enables a three-coat stucco wall to be constructed in combination with steel framing with horizontal Z-girts, to both meet the requirements of ASTM C1063 and provide a high-performing stucco wall system.

Other Options:

ONE-COAT SYSTEMS FOR ENERGY EFFICIENCY:

Various proprietary One-Coat systems over foam improve the energy efficiency of a building. Structalath 316 and Structalath Twin Trac 316 have been used successfully over foam board insulation on wood sheathing or steel framing with Dens glass or on open-frame to increase the R-value in 1/2″ or 7/8″ stucco systems. The 316 – decreased furr versions of Structalath does not deform the foam and provides a solid plaster base for full wire embedment.

Minimize fastener thermal breaks

Structa Wire × DuPont™ ArmorWall™: Continuous Insulation as an Energy Efficient System: 
Energy code requirements increasingly demand true continuous insulation (CI) — but traditional lath assemblies, which fasten through the insulation layer into stud framing, can create thermal bridging that undercuts the very performance the wall system is designed to deliver. Structa Wire is engineered to fasten directly to the DuPont™ ArmorWall™ panel, without extending fasteners through to the stud framing. That means the continuous insulation layer stays intact — no thermal shorts, no compromised R-value at every fastener point.
Why it matters:

• Preserves continuous insulation performance — supports ASHRAE 90.1 CI and thermal bridging code requirements as part of the ArmorWall syste.
• Code-backed — validated per 2024 IBC and ASTM C926/C1063, with third-party evaluation from Intertek (Letter Report 106339481MID-001a)
• System-engineered, not just compatible — Structa Wire lath was developed and tested specifically for direct-to-panel attachment on ArmorWall
• Sustainability-aligned — part of a GreenCircle-certified, LEED-eligible wall assembly
