Triple White Glass SOLAR with special coating for thermal insulation [ ] W hat is special about it? T riple white glass SOLAR features the combination of the SOLAR special coating with ultra white float glass. T riple insulation glass exhibits an extremely high level of thermal insulation and also a total energy transmittance factor (g-value – see below) which can, at such levels, only be realized with double glazing systems. Due to the special relationship of the Ug- and g-value, these glasses are perfectly suitable for putting solar construction into practice. During cold seasons in particular, this technique uses the low levels of insolation to full capacity and keeps the heat gained within the building. The high g-value allows for the gain of passive solar energy to be optimized, even if the building is not located in the most appropriate way or if the glazing is not directed exactly southwards. [ ] Your advantages The total energy transmittance of SOLAR triple white glazing exceeds that of standard triple glazing by 20%. For this reason, the solar energy gain also increases by 20 %. Your advantage is additional, free of charge heating due to the glazing! [ ] W hat are the advantages for the climate? C limate protection currently becomes increasingly important. The efficient use of energy is one of the most crucial measures in the battle against climate change. Internorm climate protection windows achieve optimal solar energy gains and guarantee maximal thermal insulation due to the energy- saving triple glazing technology and the use of innovative white glass with SOLARcoating. This leads to a reduction of CO2 and SO2 emissions.. [ ] SOLAR and white glass: more light – more brilliancy H igh levels of light transmittance ensure pleasant brightness inside: an important advantage during dark winter months in particular. Less artificial light will be required. Normal glass displays a slight greenish colour which becomes apparent when looking through double glazed panes. White glass, however, is neutral and brilliant when viewing through the panes. g-value: What is this? The total energy transmittance factor (gvalue) shows, which percentage of the incoming sun energy is transmitted through the glazing into the room. special coating SOLAR loss of thermal heat U-value inside solar additional energy gain g-value white glass reflexion U-value g-value
