Glass for Construction Purposes
A new Energy Saving Directive (EnEV) has replaced the former Heat Insulation Directive from 1995. The new directive contains even stricter stipulations for heat insulation. The average U value (unit of heat loss) of a building structure must now lie between 1.05 and 0.44 W/m²K for residential housing with a maximum 30% proportion of window area. For non-residential buildings with minimum 30% window area, the U value required is between 1.55 and 0.58 W/m²K.
Application
| | NEUTRALUX can be used in all types of buildings, and offers both optimum heat insulation and high light permeability. Heat is gained passively from sunlight passing through the glazing units. The glazed areas are also highly light-permeable. |
| Function | | NEUTRALUX Insulating Glass Units generally comprise float glass panes that comply with structural requirements and a two-level non-permeable edge sealant. An ultra-fine, almost invisible coating of precious metal covers one surface of the space between the panes. The gap contains an inert gas filler (e.g. argon) and the distance between the panes is optimized, almost completely eliminating heat loss and further improving the U value. |
| Benefits | |  | Active environmental protection: Reduction in consumption of heating energy; reduction in harmful emission levels | | Combination of high heat insulation (U value) with high solar heat gain (g value) | | Optimum light permeability | | Draughts minimized | | No frost on the inside of the windows |
