PROBLEM OF CONDENSATION
External Condensation days for TGU and DGU across Europe
SGG VIEWCLEAR II developed in 2014
• Designed to significantly reduce the external condensation
days of insulated glazing unit (by 80 to 95 %)
• No solar heat gain degradation (even improvement!)
• Optimized aesthetics (neutral colors)
• Suitable for use in IGU with positioning as outside facing
• Easy to process coating (storage, tempering)

EGLASS
Electrically heated glass
• Heat is created in (temperable) low-e coating – no wires, invisible
• Functions: Heating/comfort heating, anti-condensation, snow-melting
• Has been developed in Alavus, Finland
• 230 VAC or 48 VDC
• Accessories
• Thermostat to guide the surface temperature or energy supply
• Transformer in case 48 V is required
