* Low-E coating can be placed on the 2nd or 3rd surface of the insulating glass unit.
Şişecam Glass performances are calculated with WinSLT.
“Daylight” and “Solar Energy” properties are calculated using spectral measurements in compliance with EN 410:2011.
“U-value” is calculated according to EN 673:2011. The emissivity measurements used for calculations are in compliance with EN 673:2011 (Annex A) and EN 12898:2019.
Thermal stresses or building codes may require the use of heat-treated glass. This document is not an evaluation of the risk of glass breakage from thermal stresses. Please contact Şişecam Flat Glass to ensure the correct form of glass to be supplied for the structure.
Şişecam Flat Glass cannot be held responsible for any deviations between the presented data and the conditions on the site. This document is for informational purposes only. Technical and other data are based on information available at the time of preparation of this document and are subject to change by Sisecam Flat Glass without notice.
Daylight Transmittance (%): The ratio of the visible spectrum (light) that is transmitted through glass.
Daylight Reflectance (outdoor) (%): The ratio of the visible spectrum (light) that is reflected outside by glass.
Solar Factor: The percentage of total solar radiant heat energy entering the room thorough the glass. The lower solar factor means better solar control.
Shading Coefficient: The ratio of solar factor of a particular glass type to the solar factor of 3 mm clear float glass, set in identical conditions. The lower shading coefficient means better solar control.
U value (W/m2K): A measure of the rate of heat loss of a building component. The lower U value means better heat control and more comfort in winter.
Quality Şişecam Low-E Glass is manufactured in accordance with EN 1096 Glass in Building - Coated Glass. |
