👉 The term "atticized" is a construction term that refers to the process of adding insulation and/or moisture-resistant materials to an existing attic space. This can be done by applying a layer of drywall, insulation, or other materials over the existing walls in order to prevent the growth of mold, mildew, and pests. Atticization is often used in homes where there are no other natural means for cooling the interior temperature, such as air conditioning units or windows.
