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)

What about dynamic glass solutions?

External blinds…

Internal blinds as cheapest option…

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
