NettetFrom a functional point of view, external insulation can achieve higher levels of insulation with little risk of moisture problems either internally or within the wall structure, assuming it is correctly installed. It also maintains the thermal mass of the building by keeping the masonry within the insulation envelope. NettetLoad-bearing masonry buildings are a significant portion of the existing building stock. Given the Building America goals of reducing home energy use by 30%-50% (compared to 2009 energy codes for new homes and pre-retrofit energy use for existing homes), insulation and air sealing of mass masonry walls will need to be a
