how we can redcuce the heat transfer from glass (like windows,etc.)?

Answer 1

There are coatings that can be put on the inside of a multilayer pane of glass that reflect heat back into a heated room. Multiple layers with a vacuum or argon gas inside also have less transmission of heat. There are also thinsulate-type lined curtains you can put in front of the glass if you are talking a window.

Answer 2

Put a low conductivity gas between two panes of glass and seal them. This is often what is done to prevent heat transfer. If you look at a cross section of a thermos, it's the same concept. The less surface contact there is, the less heat transfer there will be. Another method used is using low emissivity coatings reduce radiative heat transfer.

Answer 3

Double insulated windows reduce heat transfer extensively. You still need to caulk then though.
