Elimination of the backer bar saves time and money by reducing the amount of materials and labor needed to install the spandrel insulation.

Fire Resistance

Thermal Comfort

Eliminating the backer bar from the spandrel area allows for thicker Thermafiber FireSpan insulation to be installed. The thicker insulation increases the overall R-value of the building envelope.
