Abstract
An insulating glass (IG) window unit, and/or a method of making the same is/are provided. The IG window unit includes two spaced apart substrates that are separated from one another by at least one seal and/or spacer. One of the substrates supports both a solar management coating for blocking significant amounts of infrared (IR) radiation and a coating for blocking amounts of ultraviolet (UV) radiation.
Claims19
An IG window unit comprising:
- a first glass substrate supporting a solar management multi-layer coating;
- a second glass substrate spaced apart from the first glass substrate,
- wherein one of the first and second substrates supports both a solar management multi-layer coating and a UV blocking coating including at least one layer, wherein the UV blocking coating is located over and contacting the solar management coating on the one substrate;
- wherein the solar management coating comprises at least one IR blocking layer comprising Ag, at least one dielectric layer provided between the IR blocking layer and the one substrate, and at least another dielectric layer provided over the IR blocking layer, and wherein the solar management coating has an emissivity (En) of no greater than 0.10 and/or a sheet resistance (Rs) of no greater than 8 ohms/square;
- wherein the solar management coating is a sputter-deposited coating, and the UV blocking coating is not a sputter-deposited coating;
- wherein the UV blocking coating blocks at least 50% of UV radiation from 300 to 380 nm;
- and
- wherein the IG window unit has a visible transmission of at least about 60%, and blocks at least about 80% of UV radiation from 300-380 nm.
