Solar shading glass is multi-pane insulating glass with special solar shading properties. It reduces light penetration and is also used as thermal insulation. A distinction is made between absorbent glass and reflective glass. Absorbent glass is usually tinted (bronze, green or grey). It absorbs the thermal radiation from the sun and emits it in part to the interior room. Reflective glass is fitted with a metallic vapour plate (gold, silver, bronze) in the space between the panes and reflects the thermal radiation.Insulating glass with an integrated photovoltaic module for supplying solar power, solar shading foils or aluminium louvre blades in the space between the panes serves as solar shading, screening and anti-glare protection, which can be operated without an external power supply.
