Clear wall meets energy code thermal requirements without stud cavity insulation.

Clear wall U-Factor is based on the stud size & spacing noted above and is calculated per IECC 2015 & ASHRAE 90.1-2013 Appendix A.

Clear wall effective thermal performance is based on the stud size & spacing noted above, manufacturer literature and industry studies on the thermal performance of facades.
