Why 4C ECO™

When cost, carbon, and performance all matter.

Better budget control

Familiar wood materials and factory-controlled production improve cost certainty, speed, and precision.

Lower-carbon performance

Efficient materials and continuous insulation help lower carbon and improve comfort. The integrated WRB provides a continuous air and water barrier.

Built for Type V at scale

Fits traditional design, permitting, financing, and trade workflows, enabling industry adoption within established practices.

The 4C Platform

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.
