System 3E Interlocking Wall System
System 3E is a wall system built from precision-made interlocking elements. The main wall courses stack without conventional mortar between them, and the insulation is built into the wall material itself. It offers a different way to build than conventional masonry.
Why Now
Why Builders Are Looking at New Ways to Build Walls
The U.S. has been short of skilled construction workers for years, and the gap keeps growing. The industry needs an estimated 349,000 new workers in 2026 alone. Builders need wall systems that help their crews get more done and that new workers can learn quickly.

- Built for Today's Workforce: System 3E walls go up by stacking interlocking elements. Experienced crews can put it to work, and new workers can learn it, which opens the trade to more people.
- A Simpler Process: The main wall courses stack without conventional mortar between them, so there is no mortar to mix and spread between those courses.
- Less Time on Site: The manufacturer documents about 10 square feet of wall assembled in under 5 minutes.
- Insulation Built In: The wall elements are made with insulating material, so the wall and its insulation start as one product.
