Abstract:
A method of making a vehicle windshield, the method comprising:providing first and second glass substrates, and making at least the first substrate via a float process utilizing a tin bath so as to cause the first substrate to have a tin surface and a non-tin surface ion beam milling the non-tin surface of the first glass substrate so as to remove at least 2 Ã¥ of glass from at least a portion of the first substrate and form an ion beam milled surface of the first substrate; sputtering a coating, including at least one infrared (IR) reflecting layer, on the ion beam milled surface of the first substrate; and laminating the first substrate with the coating thereon to the second substrate via a polymer inclusive interlayer so that the coating and the interlayer are provided between the first and second substrates.
