Definitions

  • the present invention relates to a glass sheet coated with a low light transmittance solar control layer stack comprising a single silver layer.
  • the solar control coated glass sheet is designed to be used in a low light transmission solar control glazing characterized through low external and internal reflectance levels, said solar control glazing being a double glazing unit.
  • the solar control glazing may be arranged in a door or a window and may be used in various types of buildings like office buildings, commercial buildings, hotels, hospitals and homes.
  • One important function of solar control glazing is to prevent overheating by solar radiation into the interior of a building, thereby improving comfort and also reducing the cost of air conditioning systems.
  • One main request of the architects is that windows incorporating such glazing should moreover fulfil certain aesthetic specifications, namely in terms of color of transmitted and/or reflected light and in terms of levels of light reflectance. These requirements are particularly difficult to satisfy when the glazing has to be heat treated at very high temperature because such treatments most often alter the visual aspect of the final window.
  • a very well-known layer stack consists of a magnetron sputter coated layer system which comprises from the glass (GL) outwardly: (1) a first silicon nitride layer (ShNL) ; (2) a first metallic barrier layer of nickel-chrome (NiCr); (3) a silver layer ; (4) a second metallic barrier layer of nickel-chrome ; a second silicon nitride layer.
  • This arrangement (GL / ShN 4 / NiCr / Ag / NiCr / ShN 4 ) is known from the early nineties (see for example EP567735A1) and has often been modified in terms of composition and thicknesses in order to allow tailor made stacks for different purposes.
  • the metallic barrier layers play multiple roles in this stack. They protect the silver layer against undesirable elements, like oxygen, mostly during heat treatment, they also absorb or reflect some light. Depending their thickness, light transmission and reflection will be differently affected. This type of layer stack can undergo heat treatment and still achieve the required colors in reflection and transmission.
  • EP2303791A1 explains that for this type of layer stack, thinning the NiCr layers results in lower DE* values, which means a better matchability of the colors of a heat treated and a non-heat treated glazing.
  • EP646551A1 teaches that a particular thickness ratio between both metallic barriers is necessary to reach a higher visible light transmittance and a low sheet resistance: the thickness of the first nickel-chrome layer must be between 2 and 5 nm while the second nickel-chrome layer must be kept 0.7 to 1.5 nm.
  • a glass substrate is sputter coated, in a manner known in the art, with the layer sequence described in the table 1.
  • Table 1 also indicates the preferred, more preferred and most preferred thickness ranges for the different layers.
  • the sequence of layers is indicated outwardly, starting from the glass substrate and the layer thicknesses are given in nm.
  • the layer stack of the present invention comprises only a single silver layer.
  • the first metallic barrier layer has a different thickness than the second metallic barrier layer and the thickness of the first metallic barrier layer is greater than the thickness of the second metallic barrier layer.
  • the sum of the thicknesses of the first and the second metallic barrier layers is greater than the thickness the silver layer.
  • the second silicon nitride layer is thinner than the first silicon nitride layer to fulfil our aesthetic requirements.
  • the coated substrate of the invention has an external reflectance smaller than 20%.
  • an additional protecting topcoat (6) is deposited above the solar-control layer stack, that is above the second silicon nitride layer, possibly in direct contact with the second silicon nitride layer.
  • the protecting topcoat is advantageously chosen from zirconium oxide, titanium oxide or mixture titanium oxide and zirconium oxide.
  • the protecting topcoat is a mixed titanium zirconium oxide (TZO) and the Ti0 2 :Zr0 2 weight ratio is comprised between 25:75 and 65:35.
  • the protecting topcoat preferably has a geometrical thickness of at least 1 nm, more preferably at least 2 nm and most preferably at least 3 nm.
  • the protecting topcoat preferably has a thickness of at most 10 nm, more preferably at most 8 nm and most preferably at most 6 nm.
  • the layer stack of the invention has the following structure, outwardly from the glass: ShNU / NiCr / Ag / NiCr / ShNU / TZO, the mixed titanium zirconium oxide topcoat being optional.
  • the single silver layer is directly contacting both metallic barrier layers.
  • both metallic barrier layers are contacting a silicon nitride layer on one side and the single silver layer on the other side.
  • the coated substrate of the invention is subjected to a thermal treatment at a temperature exceeding 600°C for a period below 10 minutes, preferably in air.
  • the present invention also concerns a multiple glazing unit, for example a triple glazing unit or a double glazing unit, comprising a solar control coated glass substrate of the invention.
  • a glazing of the present invention may be arranged in a window frame or a door frame.
  • the double glazing unit of the invention has a light transmittance greater than 10% and smaller than 40%, more preferably smaller than 36%, most preferably smaller than 34%.
  • the double glazing unit of the invention has a pleasant color in external reflection, characterized by a CIELAB coordinate b*R 0U t value between -12 and -3, preferably between - 11 and -4 and by a CIELAB coordinate a*R 0U t value comprised between -4 and 0.

  • the second nickel chrome metallic layer has a thickness comprised between 1 and 6 nm
  • the first silicon nitride layer is thicker than the second silicon nitride layer
  • the silver layer is the only silver layer in the layer stack.

However, it is not excluded for this layer optionally to contain a few traces of nitrogen or oxygen. Specifically, the atmosphere during the deposition of this metallic layers may consist of pure noble gas, for example 100% argon, or the atmosphere may contain a small amount of nitrogen or oxygen, intentionally added or accidentally added, for example originating from neighboring deposition zones.
  • the silicon nitride (ShNU) layers (1) and (5) surrounding the infrared reflecting silver layer may be doped with at least one other element, containing up to a maximum of about 15% by weight of this other element, these layers having dielectric properties that do not differ in practice from the layers consisting of silicon nitride.

Abstract

La présente invention concerne une plaque en verre revêtue d'un empilement de couches de contrôle solaire ayant une première barrière métallique considérablement augmentée au-dessous de la couche fonctionnelle d'argent, ce qui résulte en un faible facteur de transmission de la lumière, inférieur à 40 %. Les épaisseurs des différentes couches de l'empilement sont choisies de telle sorte que toutes les exigences esthétiques sont remplies, à savoir que le facteur de réflexion à la fois la externe et interne DGU reste inférieure à 20 % et tous les paramètres de couleur sont satisfaisants lorsque la plaque en verre revêtue de la couche de contrôle solaire selon l'invention est montée dans une fenêtre à double vitrage.
