Abstract
A glazing for minimising bird collisions with glazings has at least one substrate including a first major surface. The first major surface includes one or more first regions and one or more second regions, and the one or more first regions are coated with a UV reflective coating of a thickness of at least 5 nm. The one or more second regions are at least partially coated with the UV reflective coating at a thickness of less than 5 nm, or the UV reflective coating is completely absent in the one or more second regions. The UV reflective coating is coated with a protective coating, with the protective coating being based on an oxide or nitride of a metalloid or an oxide or nitride of a metal.
Claims20
A glazing for minimising bird collisions with glazings, wherein the glazing comprises at least one substrate comprising a first major surface,
- wherein the first major surface comprises one or more first regions and one or more second regions,
- wherein the one or more first regions are coated with a UV reflective coating and the UV reflective coating of the one or more first regions has a thickness of at least 5 nm,
- wherein the one or more second regions are at least partially coated with the UV reflective coating and the UV reflective coating of the one or more second regions has a thickness of less than 5 nm or wherein the UV reflective coating is completely absent in the one or more second regions,
- wherein the UV reflective coating is coated with a protective coating,
- wherein any regions of the first major surface where the UV reflective coating is absent are coated with the protective coating,
- wherein the protective coating is based on an oxide or nitride of a metalloid or an oxide or nitride of a metal, and
- wherein the protective coating has a thickness of at least 0.5 nm but at most 15 nm.
A glazing for minimising bird collisions with glazings, wherein the glazing comprises at least one substrate comprising a first major surface,
- wherein the first major surface comprises one or more first regions and one or more second regions,
- wherein the one or more first regions are coated with a UV reflective coating and the UV reflective coating of the one or more first regions has a thickness of at least 5 nm,
- wherein the one or more second regions are at least partially coated with the UV reflective coating and the UV reflective coating of the one or more second regions has a thickness of less than 5 nm or wherein the UV reflective coating is completely absent in the one or more second regions,
- wherein the UV reflective coating is coated with a protective coating,
- wherein the protective coating directly contacts any regions of the first major surface where the UV reflective coating is absent,
- wherein the protective coating is based on an oxide or nitride of a metalloid or an oxide or nitride of a metal, and
- wherein the protective coating has a thickness of at least 0.5 nm but at most 15 nm.
A glazing for minimising bird collisions with glazings, wherein the glazing comprises at least one substrate comprising a first major surface,
- wherein the first major surface comprises one or more first regions and one or more second regions,
- wherein the one or more first regions are coated with a UV reflective coating and the UV reflective coating of the one or more first regions has a thickness of at least 5 nm,
- wherein the one or more second regions are at least partially coated with the UV reflective coating and the UV reflective coating of the one or more second regions has a thickness of less than 5 nm or wherein the UV reflective coating is completely absent in the one or more second regions,
- wherein the UV reflective coating is coated with a protective coating,
- wherein the protective layer is placed to overlap both at least one first region and at least one second region,
- wherein the protective coating is based on an oxide or nitride of a metalloid or an oxide or nitride of a metal, and
- wherein the protective coating has a thickness of at least 0.5 nm but at most 15 nm.
