Which type of glass has the best performance of thermal-insulating? 

You might know that a thermal-broken aluminum window will provide you with better thermal insulating, of course, the special structure of the profile ensures the heat can not exchange freely between outside and inside, but do you know what role the glass is playing in this course? Follow me to find more. 

1. We'd better use the Low-e glass, full name low-emissivity coated glass.  

The surface emissivity of ordinary glass is about 0.84, and that of Low-E glass is less than 0.25.

This kind of low radiation film, which is less than 1% of the thickness of hair, has high reflectivity to far-infrared thermal radiation and can reflect more than 80% of far-infrared thermal radiation back.

The far-infrared reflectance of ordinary transparent float glass and heat absorbing glass is only about 12%, so Low-E glass has a good function of blocking the transmission of thermal radiation.

it rejects heat. especially in summer, it reflect most of the sun radiation back. In winder, it keep the warmth indoor and you won't feel cold.
