When compared to clear glass with 8% exterior reflectance, OptiView is a practical choice for retail storefronts or other applications where minimizing exterior reflectance is a necessity. In applications where designers wish to reduce the green tint, low iron glass is often specified in place of clear glass. Durable pyrolytic (hard coat) surface, bendable and temperable. Contact Viracon for more information about these specialty glass substrates. And our newly designed door blinds-between-glass provides even more convenience and control over privacy and light. Viracon offers a simulated acid etched glass for applications where a reflective or Low-E coating is desired. Viracon utilizes an alphanumeric code for each coated glass product. Viracon cannot guarantee the future availability of component parts manufactured or supplied by others that are incorporated into Viracon products. Within each family, the coatings available have varying degrees of light transmittance. A specular reflection from a smooth glass surface is a mirror-like reflection similar to the image of yourself you see reflected in a store window. In our nomenclature, this is represented by the number following the dash. The tinted ply should be placed to the exterior to reduce solar heat gain. Projects. As a consequence, views from both inside and out are clear, un-obscured and virtually reflection-free. Whether your project requires a reflective, understated aesthetic or a highly durable reflective coated glass, you'll find a range of glass options to meet your objectives. This specialty glass substrate has 5% exterior reflectance. It can be used in a monolithic or laminated application. OptiView can also be laminated with the anti-reflective surfaces facing outward to provide a glass unit with 2% exterior and 2% interior reflectance. Tinted glass is available in an assortment of colors and light transmission levels. Since there is no airspace to keep the heat absorbed by the tinted exterior ply from re-radiating into the building, the solar heat gain can be improved by moving the tinted ply to the inboard. ©2020 Viracon All Rights Reserved. Pilkington OptiView™ is a color neutral, anti-reflective, pyrolytic coated product. Pilkington OptiView™ in a monolithic application, with the low-reflective coating on one surface, reduces visible light reflectance and allows more visible light to pass through, when compared to clear float glass with 8% light reflectance as standard. CrystalBlue, CrystalGray, and UltraClear are trademarks of Guardian Industries. Glass substrates are the individual plies of glass used to fabricate glass units and may also be referred to as float glass, raw glass or glass lites. For a translucent appearance in an application where solar performance requirements are minimal, Viracon offers an acid etched glass substrate. Note: Velour acid etched glass cannot be used in a glass unit with a coating. The specific glass substrate needed for a given project is typically dictated by a required solar performance or a desired appearance. Azuria, Solarblue, Pacifica, Starphire, Optigray and Optiblue are registered trademarks owned by Vitro. In a specification, the glass substrate number should be placed after the coating family and before the dash in our nomenclature. In units with multiple glass plies, it is important to specify the specific glass substrate for each ply. R / (1+R). Superior safety, security and acoustic performance. (a) The glass for the building work has a daylight reflectance not exceeding 20% (b) For the use of any material, other than glass, for the building work on – (i) the façade of the building has a specular reflectance not exceeding 10% (ii) the roof, inclined at an angle of not exceeding 20 degrees In addition to providing a specific appearance, tinted glass has the added benefit of improving performance. This improvement happens when the clear coated outboard with high solar reflectance is placed in front of the tinted glass. Viracon’s specialty glass substrates are not available with a Viracon coating applied so they are not given a numerical code. Solarcool ® Glasses An expansive palette of durable, reflective coated glasses offering a range of aesthetic options. When a tinted glass substrate is selected typically only one ply of the fabricated glass unit is tinted while the other ply remains clear. Purevision is a trademark of AGC. All glass substrates are available 1/4″ (6mm) thick. This specialty glass substrate has 5% exterior reflectance. OptiView and Optiwhite are trademarks of Pilkington. In this example, VE-85 is the coating and VE1-85 is the VE-85 coating applied to clear glass. Each substrate is available in a variety of thicknesses and can have Viracon's reflective or Low-E coatings and digital or silk-screen print, applied. Click here to see a video on Pilkington OptiView™. Each glass substrate which can have a Viracon coating applied is also given a numerical code. The natural reflectivity of glass is dependent on the type of glazing material, the quality of the glass surface, the presence … Furthermore, it provides protection from UV radiation (UVA and UVB) by blocking over 99% of UV transmittance, helping to reduce fading of the contents and interiors of a building. According to these formulas, about 8% of the light is reflected from common soda-lime window glass, assuming perpendicular incidence angle and no absorption and scattering. Viracon’s Product Search simplifies the process of selecting specific glass coating and color combinations. Reflective glazing is also used by many architects because of its glare control and uniform, exterior appearance. Pilkington OptiView™ Range offers following benefits: Products for Digital Signage and Touch Screens, Design Solutions Using High-Performance Glass, Properties and Performance of Vacuum Insulated Glazing. Viracon also offers a few specialty glass substrates developed for limited use in specific applications. This nomenclature is meant to aid in specifying our fabricated glass products however is not enough on its own to clearly identify the full glass unit. As a consequence, views from both inside and out are clear, un-obscured and virtually reflection-free. Clear is the most commonly specified glass substrate and has a slight green tint. The terms and brands listed above are trademarks of Viracon. Reflective glazings are usually used in commercial buildings for large windows, for hot climates, or for windows with substantial solar heat gains. Pilkington OptiView™ is a laminated glass with anti-reflective coatings on surfaces #1 and #4 (both outer surfaces of the laminated glass), which reduces interior and exterior visible light reflectance to less than 2%. Reduces exterior and interior visible light reflectance to less than 2%. Clear and each of the low iron substrates are also available in thicknesses of 3/16″ (5mm), 5/16″ (8mm) and 3/8″ (10mm). Due to their unique characteristics, specialty glass substrates cannot be combined with Viracon's reflective or Low-E coatings.
