Precast Concrete Fire Wall

Fire wall from AC Miller is an engineered post and panel system of columns and slide-in panels for constructing a fire resistant wall. In most applications, a complete fire wall can be constructed in less than a day.  These walls are designed to withstand high temperature and provide 2 hour fire protection.

In addition to fire protection, precast concrete walls also provide ballistic and impact resistance as determined and rated by the thickness of the walls.
