The thermopaque glass is a semitransparent structure. The thermopaque glass is configured for use as the transparent material used in a window into a building. The thermopaque glass is a composite laminar structure. The thermopaque glass inhibits the passage of electromagnetic through the window into the building by reflecting a portion of the electromagnetic radiation striking the window away from the building. The thermopaque glass comprises a plurality of lamina and a plurality of interlayered resins. The plurality of interlayered resins assemble the plurality of lamina into the composite structure of the thermopaque glass. Each of the plurality of lamina is a plate selected from the group consisting of a transparent plate and a semitransparent plate.
