Overview of SILVERSTAR Low-E Coatings:

The document provides technical data on SILVERSTAR Low-E coatings, focusing on their application in double and triple insulating glass units (IGUs). The coatings are designed to enhance energy efficiency by reducing heat transfer and improving light transmittance.

Specifications:

• Ug-value: The thermal transmittance values (Ug-value) are provided for both double and triple IGUs, with values ranging from 0.6 to 1.3 W/m²K, depending on the specific coating and IGU configuration.
• Light Transmittance: The percentage of light transmittance varies between 57% and 81%, indicating the amount of visible light that passes through the glass.
• Overall Energy Transmittance: This ranges from 35% to 71%, reflecting the total solar energy passing through the glass.
• Light Reflection: Both outside and inside light reflection percentages are provided, ranging from 11% to 29%.
• UV Transmission and Absorption: UV transmission is between 9% and 29%, while UV absorption ranges from 51% to 71%, indicating the glass's ability to block harmful UV rays.
• Colour Reproduction Index: Values range from 91 to 98, showing the glass's ability to maintain true color representation.
• Selectivity Characteristics: These values, ranging from 1.1 to 1.6, indicate the balance between light transmittance and solar heat gain.

Structure and Standards:

• The document details the structure of both double and triple IGUs, specifying the layers of EUROFLOAT glass and argon cavities.
• Calculations for luminous and solar characteristics are based on the European standard EN 410:2011, and the Ug-value is determined according to EN 673:2011.

Additional Information:

• Temperable coatings are available, with technical characteristics adapted for tempering, although they may differ in color.
• Contact information for Euroglas GmbH and its subsidiaries in France and Poland is provided for further inquiries.
