Florida Commercial Glazing Spec
Solarban vs Viracon low-E glass — commercial spec comparison
Solarban (Vitro) and Viracon are the dominant tier-one low-E coated glass manufacturers used in Florida commercial glazing. Solarban 70XL is the Florida default for hospitality and office. Viracon VRE-67 is the alternative — slightly higher VLT. Performance is comparable; spec selection depends on architect preference and project-specific SHGC/VLT/U-factor requirements.
