<p>PURPOSE: A laminated glazing reflecting the sunlight and the heat ray is provided, to prepare the sandwiched glass which has an insulating function in addition to a sunlight protective function. CONSTITUTION: The transparent laminated glazing is integrated by a transparent insertion sheet of a thermoplastic type; at least two glass windshields of a sunlight protective coating which reflects the rays exclusive of a visible spectral range of the sunlight, more particularly IR rays; and a transparent coating of a low radiation type which reflects the heat rays on the surface facing a cab and is installed inside the sunlight protective coating. The coating for reflecting the heat rays is made of metal oxides, preferably tin oxides coated with fluorine and is deposited by pyrolysis. The sunlight protective coating is made of silver-based metal oxide, AlN or Si3N4.</p> |
