A reinforced insulation material having one or more sheets of insulation material having a plurality of voids in each sheet, wherein the sheets are operably connected to each other in a layered configuration, the voids mate to each other to create cylindrical or rectilinear pathways for insertion of adhesive or synthetic material to adhere the sheets into a layered or sandwiched configuration. The voids may be a variety of shapes including circles, squares, rectangles or other suitable shapes that upon formation of the layered sheets line up to permit insertion of material or dowels to create a reinforced assembly. The layers may be formed into a variety of shapes including a semicircular shape to go around a pipe, or a block of material. The finished assembly withstands compressive forces and provides insulation when in place around pipes or under tanks.
