The Future of Building Has Arrived
Fortex UltraWall™ isn’t just an upgrade — it’s a complete reinvention. Built to resist fire, hurricanes, and earthquakes while saving energy and preserving forests, it sets a new standard for safer, smarter, and more sustainable homes.
Innovating How You Live, Not Just How You Build
Mrcela Custom Homes is proud to be the first builder to bring Fortex UltraWall™ technology into residential construction. The first three Fortex homes are being developed inside Lake Nona Country Club in Orlando, Florida, one of the nation’s most prestigious private communities.
Made to Defy Nature
Fire-Resistant Technology
UltraWall™ XShield™ is completely fireproof. Its dual high-strength concrete shells and non-combustible EPS core create a wall system that cannot burn. For wildfire-prone areas like California, your home is fully protected, it simply will not catch fire.
Earthquake-Resistant Design
Every UltraWall™ is reinforced to survive major earthquakes. Fortex XLock™ connectors and precision-engineered concrete shells absorb and distribute seismic forces, keeping your home structurally sound. Even the most powerful quakes cannot compromise it.
Hurricane & Wind Protection
UltraWall™ is engineered to withstand the strongest hurricanes and windstorms. Reinforced rebar grids locked inside dual concrete shells keep the structure intact even up to Category 5 winds. Your home will stay standing no matter the storm.
Built Like Nothing Before: The UltraWall™ System
Fortex UltraWall™ isn’t just a wall — it’s a breakthrough in building technology. Designed to resist fire, hurricanes, and earthquakes while saving energy and preserving forests, UltraWall™ delivers unmatched safety, sustainability, and strength. For the first time, American homes can be built with the same resilience as critical infrastructure — faster, smarter, and greener than ever before.
