Anti Reflective Glass -SGG Vision-Lite

SGG vision-Lite is anti-reflective coated glass which can reduce the glass surface light reflection significantly.The coating can be single side or double side to suit different requirement.Monolithic vacuum coating on 6mm low iron glass light transmittance reach almost 98%.Below chart shows the glass performance between SGG VISION-LITE and China anti-reflective products.

High performance SGG Planitherm series

Planitherm series including Planitherm One,Ultra N,Ultra N diamond,1.16 ,1.3,total,total +,and Planitherm LUX,Lux Diamond,It’s mixed products of single,double ,and passive low e coatings.Max for passive house triple glazing units which require high light transmittance and extremely low thermal conductivity.

Features of Planitherm series is high light transmittance over 70%,and some coating even over 80%.Along with the high glass light transmittance,low reflectance and clear view.

Double silver low-E -SGG COOL-LITE SKN

SKN series with light transmittance from 40-70%,despite clear glass,the coating can also be applied on low iron glass,green,grey,blue glass to get better SC and lower light transmittance.

Triple silver low-E -SGG COOL-Xtreme

Triple silver low-E coating is the most advanced coating products worldwide,different from most factories,SGG developed low light transmittance triple silver coating with only 46% LT.Personally I believe this is not necessary as areas which require low light transmittance has better and more cost effective options-double silver low-E on body tinted glass.

Taking example of 55 double silver coating on French Green glass,LT is 43,SHGC 0.23,compared with SGG COOL-LITE50/22,there’s little performance difference while price can be 20% lower.
