Glass Performance Tables

Light, solar energy and thermal insulation values of the Şişecam coated glass we use in our façade projects. Daylight and solar energy values are given according to EN 410, and thermal transmittance (U value) according to EN 673.

Daylight Transmittance (%)The percentage of incident light that passes through the glass.

Solar Factor – g value (%)The percentage of solar heat energy entering the interior. A lower value means better solar control.

U Value (W/m²K)A measure of thermal insulation. A lower value means better thermal insulation.

Colour Rendering – Ra (%)How closely objects seen behind the glass match their true colours.

Low-E Glass (Thermal Control)

4+16+4 mm, coating on surface #3 (In double glazing, the coating can be on surface 2 or 3.)

⁽⁴⁾ Controls excessive sunlight by limiting solar heat gain into the building; used in commercial buildings such as hospitals, offices and shopping malls. Thanks to its reflective properties, it provides visual uniformity in curtain wall projects. Use as tempered or heat-strengthened glass is recommended.
⁽⁵⁾ Due to the nature of the coating, the colour of the base glass is more noticeable.

The values are taken from the Şişecam “Glass solutions for façades” catalogue (2025) and are for information purposes only. Actual values may differ from those given depending on conditions at the place of use. Argon values in blue and bold indicate the lowest U value (1.0 W/m²K).
