Difference between Single silver low-E,double silver low e and triple silver low e

Here we introduce several main difference to help you identify the different low e coating.

1.LSG. LSG is the ratio between the glass light transmittance and SHGC.

Double silver low e has relatively lower SHGC than triple silver low e based on same light transmittance.

The LSG of single silver low e is around 1.4,while double silver one can be over 1.6-2,triple silver low e LSG can reach 2.2 or even more.

Which means that under the same light transmittance,the double silver low e and triple one can reach lower SC value and transfer the lighting to cold light,low e U value performance

3.Price.

Double silver low e glass is about USD3-4/SQM higher than single one ,and triple silver low e is about USD10/sqm higher than double one.

But the cost performance for triple one is not good,so in most cases we recommend double one and the best cost performance low e for glass facade.
