Since 1990s,scientist keep developing new low-E coatings to help decreasing the windows &glass facade energy consumption,from single silver low-E,to double silver low-E,triple silver low-E to now quad silver low-E.

The quad silver low-E developed by Taiwan glass has an monolithic light transmittance of 75%,after insulating process,LT keeps higher than 70%.

Another important feature of the quad silver low-E is ,the inner and external surface has the same color.

This will enable more processors to manufacture and supply high end energy saving glass products to global projects.
