04Assembly Story
From flat pack to finished building.
- 01
Panelized
The building begins as a coordinated kit of factory-engineered panels and connections.
- 02
Flat packed
Components are sequenced, protected and packed to move more building with less volume.
- 03
Site assembled
A prepared local team raises the envelope through a controlled, repeatable workflow.
- 04
Finished space
Interior systems and finishes complete a durable cabin or ADU ready for real life.
05Tested Performance
Proof, built into the system.
Metal SIP technology evaluated under ICC-ES Evaluation Report ESR-5510 for the 2015–2024 IBC, IRC and IECC, with ASTM-tested data across thermal, surface-burning, structural, connection and wind performance.
