PILKINGTON ITALIA Pilkington Optitherm™ S3 Insulated low-e glass with magnetron coating

A high performance thermal insulation off-line coated glass with a Ug-value of 1.‎1 W/m2K when incorporated in a standard Insulating Glass Unit (IGU).‎ It is one of the market's leading super neutral low-emissivity glass products due to its very high light transmittance, low light reflectance and high level of colour neutrality making it ideal for large glazing areas with demanding design.‎ Pilkington Optitherm™ S3 is always supplied as part of an Insulating Glass Unit.‎ For applications requiring impact safety, we offer Pilkington Optitherm™ S3 Pro T which must be toughened and is colour matched to Pilkington Optitherm™ S3 after toughening.‎ Pilkington Optitherm™ S3 is available in combination with Pilkington Optilam™, Pilkington Optiphon™ or Pilkington Activ™ to offer additional benefits such as impact resistance, increased security, improved noise reduction or additional self-cleaning properties.‎ Glass from the Pilkington Optitherm™ range is designed to be assembled into insulating glazing.‎ The low emissivity coating deposited off-line on the glass gives the Pilkington Optitherm™ range very high thermal insulation performance combined with excellent colour neutrality.‎ Solar energy enters the building mainly as short wave radiation but, once inside, is reflected from objects back to the glass as long wave radiation.‎ Low-emission glass has a coating that effectively counteracts heat loss, allowing solar heat to enter and preventing the energy emitted from the interior radiating bodies from escaping.‎ Heat loss is generally expressed as a U-value, which corresponds to the heat loss in Watts per square metre for each degree Kelvin of temperature difference between the interior and exterior (expressed as W/m2K); the lower the U-value, the better the insulation guaranteed by the product.‎ Basically, low-E glass reflects energy back into the room, with a significantly reduced heat loss compared to normal float glass.‎ In addition, various types of low-e glass allow for passive solar gain of varying degrees, which helps reduce heating needs and costs, especially in the colder months.‎
