A glass article having a solar control coating is disclosed for use in producing heat reducing glass especially for use in architectural windows. The coated article includes a glass substrate, a coating of an antimony doped tin oxide deposited on and adhering to the glass substrate and a coating of fluorine doped tin oxide deposited on and adhering to the surface of the coating of antimony doped tin oxide. The low emittance of the coated glass article, when combined with the surprisingly selective solar absorption of the multilayer stack provides improved heat rejection in summer and heat retention in winter, while permitting the transmittance of a relatively high degree of visible light.

Glass article having a solar control coating

A color neutral absorbing film is applied as a coating on a glass substrate, to which a conductive coating is first applied. An additional metal oxide layer is deposited on the absorbing film. The coating is suitable for use in anti-reflective coatings containing other metal oxides or mixed metal oxides to achieve a coated glass article having a visible light transmittance of 30% or greater and a reflectance of less than 5%. The coated glass article is absorbing, anti-reflective and conducting.

Glass article with anti-reflective coating

The present invention is an anti-reflective transparent article which includes a transparent substrate. The article also includes a first coating of metal oxide applied over the substrate. The first coating of metal oxide has a reflective index of about 1.8 to about 2.6. The article further includes a second coating of a metal oxide applied over the first coating of metal oxide. The second coating has a refractive index of about 1.44 to about 1.6. The reflectivity of the article, when measured at an angle of at least 50 degrees from normal, is at least three percentage points less than the reflectivity of the uncoated substrate at the same angle.

Anti-reflective films

A method of producing mirrors comprising depositing onto a ribbon of hot glass during the production process a coating comprising at least one pyrolytic reflecting layer and at least two reflection enhancing layers, the last applied or outer of the enhancing layers also serving as a protective layer for the coating. The mirrors have a visible light reflection of at least 35% and less than 70% and exhibit a bright silver or chrome appearance. There is also a provided a mirror having such a coating.

Coated glass article

An anti-reflective glass article including a glass substrate, a first coating of a metal oxide and a second coating of a metal oxide. The first coating of metal oxide is applied over the substrate. The refractive index of the first coating of metal oxide ranges from 1.8 to 2.6. The thickness of the first coating is greater than l/(4*n), wherein l equals a design wavelength in the visible spectrum and n equals the refractive index of said first coating of metal oxide. The second coating of metal oxide is applied over the first coating. The second coating of metal oxide has a refractive index of about 1.45 to about 1.6 and a thickness of less than l/4(n).

A glass article used for producing a coated, solar control glass for architectural windows. The coated article includes a glass substrate, a coating of a titanium oxide deposited on and adhering to the surface of the glass substrate, a coating of silicon dioxide deposited on and adhering to the surface of the coating of the titanium oxide, a second coating of titanium oxide deposited on and adhering to the surface of the coating of the silicon dioxide, and an outer coating of a conductive metal oxide deposited on and adhering to the surface of the second coating of the titanium oxide. A specific coating stack on the glass substrate provides a neutral colored article having a high visible light transmittance, a reduced solar energy transmittance, a low emittance, and a high total solar reflectance. The use of the article in architectural glazings results in a glazing that reflects solar energy in the summer and provides a low U value for the winter.

Coatings on glass

A method of producing mirrors comprising depositing onto a ribbon of hot glass during the production process a coating comprising at least one pyrolytic reflecting layer and at least one color modifying layer whereby the mirrors exhibit color in reflectance and have a visible light reflection of at least 35% and less than 70%. There is also a provided a mirror having such a coating.

A method for applying a coating to a substrate comprises a gas distributor having an outlet disposed adjacent to the substrate for directing a gaseous reactant mixture to the surface of the substrate. A plurality of drop tubes are provided which communicate with and are spaced along the length of the distributor for supplying the gaseous reactant mixture to the distributor. The uniformity of the thickness of the coating which is applied to the substrate along its width is determined. Finally, one or more of the reactants or an inert gas is supplied to one or more of the drop tubes to alter the concentration of one or more of the reactants in the gaseous reactant mixture flowing through one or more drop tubes. The rate of deposition of the coating in the proximity of such drop tubes is thereby altered to improve the uniformity of the coating deposited.

A glazing unit having incorporated therewith a solar control filter, comprising combinations of layers of transparent films adhered to the surface of a transparent glass sheet. A protective covering is provided over the coating stack. The coating stack includes at least three layers of zinc oxide and at least two layers of silver deposited alternately one upon another, with each layer of silver between two layers of zinc oxide. The glazing unit exhibits color compatibility in environments, where normally employed. The electrically conducting silver layers enable the coating stack to optionally be utilized as a defogging and deicing system for the unit.
