Solar+ Glass

Internorm's new energy efficient standard glass

Internorm's new standard glass is characterised by its special coating SOLAR+. The triple insulating glass features extremely high thermal insulation as well as an overall energy transmission factor (g value -> see below) which can otherwise only be achieved at this level with double glazing. Due to this exceptional rate of thermal insulation (Ug) and energy transmission (g value) this glazing is perfectly suitable for implementing in solar buildings.

Especially in cold season, it uses low solar radiation to its optimum and keeps the gained heat in the building. The high g value makes it possible even in not ideal building positions or in not precisely south-facing glazing positions to optimise the gain on passive solar energy.

The windows are the heating

With triple glazing SOLAR+ the overall energy transmission is 20% higher than with standard triple glazing. Thus the solar energy gain also increases by 20 %. Through the glazing you have additional free of charge heating!

Helping climate protection

Efficient use of energy is one of the most important measures against climate change. Internorm's climate protection windows achieve optimal solar gain and guarantee maximum thermal insulation thanks to the energy saving triple pane technology and the innovative special coating SOLAR+. This reduces emission of CO2 and SO2.

More light and brilliance: SOLAR+

The high transparency of SOLAR+ creates friendly brightness on the inside of the building - an important asset especially during the dark winter months.

g value

G Value

The 'g value' indicates how many percent of incident solar energy will reach the room through the glass. Identical glass thicknesses according to EN 410 result in a g value of 61% and light transmission of 73%.
