PROBLEM TO BE SOLVED: To provide a pair glass with high impact resistance, with excellent heat and sound insulating effect, hardly bringing about moisture condensation and being low-cost. SOLUTION: In figure 1, the pair glass with a dual structure is constructed with a glass sheet 2 engaged in a frame body 1 and a substrate 3 laid in parallel and opposite thereto. Spacers 3a are integrally formed on the substrate 3 and recessing depressed parts 3b are formed on the tops thereof. Plate glass and transparent synthetic resin plates such as polyethylene terephthalate (hereinafter abbreviated to PET), waste plastics and so forth are adopted for the glass sheet 2. Synthetic resins including the waste plastics and in particular, in the case transparency is required, the transparent synthetic resins such as PET are used for the substrate 3. |
