Interpane have announced the development of a new coated basic glazing (low-E). Even the double glazing unit with standard argon filling achieves 1.1 W/m2K (Ug-value as per EN 673) at a light transmittance of 80%. A combination for excellent comfort. The higher thermal insulation of "iplus E" also reduces the energy consumption, which in view of increasing heating costs and the Energy Performance Certificate (as of 2006) is a major issue for house-builders. The innovative low-E coating provides for exceptionally high light transmittance (tL = 80% as per EN 410). The glazing is thus particularly suitable for domestic construction where plenty of natural daylight is desired. It also remains neutral in colour (Ra = 97). With a solar factor of 60 percent, "iplus E" achieves passive solar energy gain. For more information please see: www.interpane.net
