Default Question about IR and window glass.

Does anyone know how 808nm/1064nm IR reacts with ordinary window glass. Does it pass through/bounce off/other?

As far as I know, near-IR passes through, but glass is opaque to far-IR light.

So it should be safe shining a laser without an IR filter through a window assuming that I watch out for the green reflection.

It should, but I could be wrong, so be careful.
