* For a fire rating change CMU to UL rated CMU.
** Product recommendations are based on Type I-IV construction requiring NFPA 285 assembly acceptance criteria compliance per IBC Sections 1403.5 & 2603.5.5.
*** Note that specific conditions are required at the head detail of fenestration openings to maintain NFPA 285 compliance.
(proposed clear wall U-Factor is approximately 21% better than code and has a 96% thermal effectiveness)
|Design U-Factor: a||U-0.064||U-0.059|
|Effective U-Factor: b||N/A||U-0.059|
|Assembly Air Permeability||0.04 cfm/ft2 @75Pa||0.0072 cfm/ft2 @75Pa|
a Clear wall U-Factor is based on materials noted above and is calculated per IECC 2015 & ASHRAE 90.1-2013 Appendix A.
b Clear wall effective thermal performance is based on materials noted above, manufacturer literature and industry studies on the thermal performance of facades.
