PILKINGTON ITALIA - Стекло низкоэмиссионное Pilkington Optitherm™ S1

Pilkington Optitherm™ S1 Plus is the latest in our low-e range offering ultra low-emissivity and achieving a Ug-value of only 1.‎0 W/m2K when incorporated in a double glazed IGU.‎ It is a single stock product hence can be used for annealed, laminated and toughened applications being toughened after processing.‎ Pilkington Optitherm™ S1 Plus combines superior light transmittance with a highly neutral colour.‎ It is the ultimate in thermal insulation and should be specified for any situation where excessive heat loss is a concern.‎ 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.‎ Further info from manufacturer on Pilkington Optitherm™ S1 PILKINGTON ITALIA
