Energy Controller Glass (Sun Energy)

Energy controller glasses with a very thin microscopic coating of iron oxide and other metal atoms prevent the energy loss of the interior space of the building and provide a favorable light and temperature for the inhabitants. The most prominent feature of this product is the low heat transfer coefficient (U-VALUE) compared to other glasses. It has a U value 1,8 W/sqmK, and can be combined with a second low E glass to reduce the U value even more.

The basis glass used for Sun energy production is float glass conform to EN 572-1 & 2. The EN 572-1 defines the magnitude of the proportions by mass of the principal constituents of float glass is as following.
