Abstract: Each module includes a block body and an outer wear surface joined by one or more separator webs. The block body either is massive as constructed, or receives a massive filling, such as concrete, at the job site. Provision is also made for providing a filling of thermal insulation such as foamed synthetic plastic for the module. Modules are stacked and coursed to make walls. Mortar may be used between adjacent modules, and/or the module walls may be facially coated with a substance which securely interconnects the modules. Such walls have a high interior mass, insulated on the exterior and protected exteriorly of the insulation by the wear surface. The high mass tends to assume room temperature and perform as a thermal energy flywheel. Some measures for partial prefabrication of module parts are disclosed.
