Definitions
- This invention relates to a coated glass article having a solar control coating. More particularly, this invention relates to a coating stack of a titanium oxide, silicon dioxide, a titanium oxide, and a conductive metal oxide on a glass substrate that results in an article having a color neutral reflectance, a low emittance, a low solar energy transmittance, a high total solar reflectance, and a high visible light transmittance.
- Coatings on architectural glass are commonly utilized to provide specific energy absorption and light transmittance properties. Additionally, coatings provide desired reflective or spectral properties that are aesthetically pleasing.
- the coated articles are often used singularly or in combination with other coated articles to form a glazing or window unit.
- Coated glass articles are typically produced "on ⁇ line” by continuously coating a glass substrate while it is being manufactured in a process known in the art as the "float glass process”. Additionally, coated glass articles are produced "off-line” through a sputtering process.
- the former process involves casting glass onto a molten tin bath which is suitably enclosed, thereafter transferring the glass, after it is sufficiently cooled, to lift out rolls which are aligned with the bath, and finally cooling the glass as it advances across the rolls, initially through a lehr and thereafter while exposed to the ambient atmosphere.
- a non-oxidizing atmosphere is maintained in the float portion of the process, while the glass is in contact with the molten tin bath, to prevent oxidation.
- An oxidizing atmosphere is maintained in the lehr.
- the coatings are applied onto the glass substrate in the float bath of the float bath process. However, coatings may also be applied onto the substrate in the lehr.
- the attributes of the resulting coated glass substrate are dependent upon the specific coatings applied during the float glass process or an off-line sputtering process.
- the coating compositions and thicknesses impart energy absorption and light transmittance properties within the coated article while also affecting the spectral properties. Desired attributes may be obtainable by adjusting the compositions or thicknesses of the coating layer or layers. However, adjustments to enhance a specific property can adversely impact other transmittance or spectral properties of the coated glass article. Obtaining desired spectral properties is often difficult when trying to combine specific energy absorption and light transmittance properties in a coated glass article.
- a solar reducing glazing with a low emittance, a low solar energy transmittance, and a high total solar reflection would significantly improve energy costs in buildings and homes while providing a desirable neutral tint.
- a solar reducing glazing that has a color neutral reflectance, a low emittance, a high visible light transmittance, a low total solar energy transmittance, and a high total solar reflection.
- the use of a neutral colored article in architectural glazings would permit the transmission of a high degree of visible light while reflecting a significant amount of near infrared energy.
- the low emittance characteristic of the glazing would minimize any indirect heat gain from absorption.
- a novel glass article useful for producing coated, heat reducing glass for architectural windows 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 a 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.
- both titanium oxide coatings are titanium dioxide.
- the use of the present inventive article in architectural glazings results in a glazing that rejects solar energy in the summer and a provides a low U value for the winter.
- the specific coating stack on the glass substrate provides a neutral colored article having a high visible light transmittance, a reduced total solar energy transmittance, a low emittance, and a high total solar reflectance.
- the first three layers of the coating stack on the glass substrate provide a high visible light transmittance while reflecting a high amount of near infrared energy.
- the layers are a combination of low and high index quarter wave layers with a design wavelength in the near infrared region.
- the low visible light reflectance results in a visible light transmittance (Illuminant C) greater than 65%.
- the high degree of reflection in the near infrared region provides a solar heat transmittance of less than 50%.
- the outer conductive metal oxide layer reduces the emittance of the glass article to less than 0.2.
- the low emittance value minimizes the indirect gain from absorption and provides a U value of less than 0.4. It is an object of the present invention to provide a neutral colored architectural glazing that transmits a high degree of visible light and reflects a significant amount of near infrared energy.
- the present invention utilizes a near infrared reflecting stack having high and low index quarter wave layers with a design wavelength in the near infrared region. Furthermore, the present invention minimizes the number of layers in the stack while maximizing the near infrared energy reflectance by differing the index of the high and low index layers as much as possible.
- the conductive metal oxide layer of the present invention lowers the overall emittance of the glazing and thereby provides a low U value.
- the coating stacks of the present invention are specifically applied at thicknesses which result in the desired reflected and transmitted neutral color.

- molten glass 19 is cast onto a hearth 20, and flows therefrom under a metering wall 21, then downwardly onto the surface of the tin bath 15, from which it is removed by lift-out rolls 22 and conveyed through the lehr 12, and thereafter through the cooling section 13.
- a non-oxidizing atmosphere is maintained in the float section 11 by introducing a suitable gas, such as for example one composed of 99 percent by volume nitrogen and 1 percent by volume hydrogen, into the zone 18, through conduits 23 which are operably connected to a manifold 24.
- the non-oxidizing gas is introduced into the zone 18 from the conduits 23 at a rate sufficient to compensate for losses of the gas (some of the non-oxidizing atmosphere leaves the zone 18 by flowing under the end walls 17) , and to maintain a slight positive pressure, conveniently about 0.001 to about 0.01 atmospheres above ambient pressure.
- the tin bath 15 and the enclosed zone 18 are heated by radiant heat directed downwardly from heaters 25.
- the heat zone 18 is generally maintained at a temperature of about 1200 °F.

- the first three coating layers in the multilayer stack of the present invention are designed to reflect a significant amount of near infrared energy above 700 nm while transmitting a high degree of visible light below 700 nm. The attenuation of the near infrared energy reduces the solar energy transmittance of the coated article. The reflection of the near infrared energy is accomplished through the use of high and low index quarter wave layers with a design wavelength in the near infrared region.
- a greater differential between the high and low index layers increases the width of the reflection zone in the near infrared region and thereby reduces the number of layers required in the coating stack.
