High selectivity and colour neutrality are no longer mutually exclusive in solar control glass. The ratio of transparency Tv to the total energy transmittance (solar factor) can reach values as high as two in neutral Stopray glazing. A magnetron coating, sputtered onto the glass in a vacuum process, ensures optimal solar control in the summer while a low thermal transmittance (Ug) prevents heat loss in the winter. Stopray solar control panes are used as insulating glass. Besides neutral, Stopray is also available in several colours, with transparency values ranging from 47 to 61 percent. 

To ensure even better thermal insulation, AGC Interpane developed "0.9 Stopray" insulating glass. The combination of soft coating and the pyrolytic coating Planibel GfastT enables a thermal transmittance (Ug) of just 0.9 W/(m²K). The excellent solar control is achieved through the application of a selective metallic coating.

• High transparency, good solar control - little heat is radiated into the building
• Suitable for any climate: solar control in summer and thermal insulation in winter
• Available in various colours, as well as in neutral colours with low reflection
