Heat treatable coated article for use in backsplash applications
Coated articles for use in backsplash applications such as kitchen backsplashes, bathroom backsplashes, and bathroom floor/wall applications. The coated article includes a coating on a glass substrate, where the coating includes a plurality of dielectric layers and a plurality of metal-based layers and is configured so that the coated article has desirable glass side reflective coloration (e.g., bronze, blue, silver, and/or grey coloration) and is sufficiently opaque to hide adhesive used to adhere the coated article to walls/floors. The coating may be configured to realize thermal stability in order to have minimal or reduced glass side reflective color shift up heat treatment (e.g., thermal tempering).
