4C ECO™
A wood-framed building system optimized for Type V construction, combining factory-built speed, strong thermal performance, lower carbon, and cost efficiency.
Designed for efficient, scalable construction.
4C ECO is our wood-framed system for projects where cost, carbon, and thermal performance must work together. It combines continuous insulation, integrated weather protection, factory-controlled manufacturing, and coordinated installation while following traditional design, permitting, and inspection pathways.
| Specification | Detail |
|---|---|
| Frame material | Wood |
| Construction type | Type V |
| Thermal performance | Highest of our two systems |
| ICC-ES listing | Code Listed - Patent Pending |
| Recommended for | Multifamily, infill, budget-conscious projects |
| Cost profile | Better budget control versus 4C SAFE™ |
When cost, carbon, and performance all matter.
Better budget control
Better budget control
Familiar wood materials and factory-controlled production improve cost certainty, speed, and precision.
Highest thermal efficiency
Lower-carbon performance
Efficient materials and continuous insulation lower carbon and improve comfort, while an integrated WRB creates a continuous air and water barrier.
Built for multifamily & infill
Built for Type V at scale
Fits traditional design, permitting, financing, and trade workflows, enabling industry adoption without changing established practices.
Bring factory-built certainty to your next Type V project.
4C ECO brings the complete 4C process to wood-framed construction, designed for faster installation, stronger cost control, high thermal performance, and lower carbon. It is now available for planning and specification across single-family, multifamily, and infill projects.
