Three types of panels are analyzed, i.e., solid panels, hollow core panels and modified hollow core panels formed of a lightweight mortar pre-panel enveloped by a thin layer of grout. The panels are reinforced with a mesh steel or fiberglass fabric. The mechanical behavior of panels is determined from bending tests or compression tests under static loading. The use of mortars with expanded vermiculite as lightweight aggregate decreases the flexural strength of panels, but increases their thermal insulation by up to 10%. The use of fiberglass fabric prevents sudden failure of the modified hollow core panels. The main finding of this study is the technical feasibility of lightweight panels made of pre-cast panel mortar and expanded vermiculite reinforced with fiberglass fabric.porAcesso AbertoPainel pré-moldadoVermiculita expandidaFibra de vidroPrecast panelExpanded vermiculiteGlass fiberArtigo10.5216/reec.v10i3.35244
