NettetFor example, the mass wall U-Factor requirement for Chicago (Climate Zone 5) is U0.078, which corresponds to an R-Value of 12.8. As long as the wall as a whole (not the insulation alone) meets the U0.078/R12.8 requirement, the wall complies with the IECC in Climate Zone 5. Although not as NettetDue to the thermal mass, the IECC permits concrete masonry walls to have less insulation than frame wall systems to meet the energy requirements. In addition to the thermal mass benefits, concrete masonry can provide continuous insulation with an R-Value of 14 or 20 (in this typical cavity wall) depending on the type of rigid insulation …

NettetMasonry walls provide good thermal mass if they are located internally or protected by insulation. Avoid finishing masonry walls with plasterboard because this insulates the thermal mass from the interior and reduces its capacity to absorb and release heat.
