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, wherein a first one of the substrates supports a solar management coating for blocking significant amounts of infrared (IR) radiation and the other one of the substrates supports a coating for blocking amounts of ultraviolet (UV) radiation.
Claims30
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, the second glass substrate supporting a UV blocking coating including at least one layer;
- wherein the solar management coating supported by the first glass substrate comprises first and second IR blocking layers each comprising Ag, at least one dielectric layer provided between the first IR blocking layer and the first substrate, at least another dielectric layer provided between the first and second IR blocking layers, and wherein the solar management coating supported by the first substrate 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 UV blocking coating supported by the second substrate 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.

A window unit comprising:
- a first substrate supporting a coating;
- a second substrate spaced apart from the first substrate, the second glass substrate supporting a UV blocking coating;
- wherein the coating supported by the first substrate has an emissivity (En) of no greater than 0.20 and/or a sheet resistance (Rs) of no greater than 20 ohms/square;
- and
- wherein the window unit has a visible transmission of at least about 60%, and blocks at least about 80% of UV radiation from 300-380 nm.
2 more elements
A method of making a window unit, the method comprising:
- depositing a solar management coating on a first substrate, the solar management coating comprising at least one layer for blocking at least some IR radiation;
- forming a UV blocking coating that blocks at least some UV radiation on a second substrate;
- and
- coupling the first and second substrates to one another so that the respective coatings face each other across a gap provided between the substrates, and wherein the window unit has a visible transmission of at least 60% and blocks at least about 80% of UV radiation from 300-380 nm.
