Proven Performance of U-STUCCO™

In a full-scale Southern California Edison (SCE) wildfire burn test, U-STUCCO™ was applied to high-density housing structures to evaluate its ability to harden buildings against extreme fire exposure. The results were clear and dramatic:

• The structure protected with U-STUCCO™ remained intact, resisting ignition, flame spread, and structural compromise throughout the test.

• The unprotected control structure failed rapidly, igniting and collapsing in less than an hour.

• Independent building scientists documented that U-STUCCO™ provided critical life-safety advantages:

  • Extended escape time for occupants.

  • Increased response time for firefighters.

  • A significantly higher probability of the structure surviving wildfire events.

This real-world test validated U-STUCCO™ as a true fireproofing solution for wildfire-prone regions, proving its ability to outperform conventional stucco and claddings. By preventing ignition and flame spread under severe conditions, U-STUCCO™ helps create safer, more resilient communities — while lowering long-term risk and insurance costs.
