As sunlight passes from air through glass and back into air again , i.e. , through a window , what constituents will be extracted ?

I would imagine the only thing that would be "extracted" would be energy in the form of heat.

You pass NIR and visible reasonably well, and filter out some other IR and UV

Is there a question here?

Swansont , I understand the graph you provided and the link is totally relevant to what I am asking about . For the unknown reader who is yet to understand transmissivity and the different wavelengths that make sunlight , I provided the 2 links and the graph as background information .

 

As for a question , here I am again . Why , for soda lime glass , is the derivative of transmissivity with respect to wavelength so severe of a drop when the wavelength is in a narrow range around approximately 2.6 micrometres ?

There is presumably some transition(s) that absorb the light that has a cutoff at that wavelength.

"Why , for soda lime glass , is the derivative of transmissivity with respect to wavelength so severe of a drop when the wavelength is in a narrow range around approximately 2.6 micrometres ?"

I think the essence of the answer is explained here

It's a resonance effect.
