Abstract
A method of making a window unit is provided which may result in improved yields. In certain example embodiments, the method involves coating a substrate with both (i) a solar control/management coating, and (ii) a protective layer (e.g., of or including diamond-like carbon (DLC)) over the solar control/management coating. The protective layer protects the coated substrate from scratches and/or the like during processing prior to heat treatment. Then, during heat treatment, the protective layer(s) is burned off in part or in whole. Following heat treatment, the coated article (substrate with solar control/management coating thereon) is coupled to another substrate in order to form the window unit.
Claims16
A method of making a window unit, the method comprising:
- providing a coating on a glass substrate, the coating including at least one layer comprising Ag;
- depositing a protective layer comprising diamond-like carbon (DLC) on the glass substrate over the coating;
- heat treating the glass substrate with the coating and protective layer thereon so that the protective layer comprising diamond-like carbon (DLC) at least partially burns off during the heat treating;
- and
- following said heat treating, coupling the glass substrate with the coating thereon to another substrate in order to form the window unit.
A method of making a window unit, the method comprising:
- providing a solar control coating on a glass substrate;
- ion beam depositing a protective layer comprising diamond-like carbon (DLC) on the glass substrate over the coating;
- heat treating the substrate with the coating and protective layer thereon at a temperature of at least 570 degrees C. so that the protective layer comprising diamond-like carbon (DLC) at least partially burns off;
- and
- following said heat treating, coupling the glass substrate with the coating thereon to another substrate in order to form the window unit.
A method of making a window unit, the method comprising:
- providing a solar control coating on a glass substrate;
- depositing at least one temporary protective layer on the glass substrate over the coating;
- heat treating the substrate with the coating and protective layer thereon at a temperature of at least 570 degrees C. so that the protective layer burns off;
- and
- following said heat treating, coupling the glass substrate with the coating thereon to another substrate in order to form the window unit.
