What is the correct way to make glass surfaces modeling wise

[nildoe]

So the title says it all, i'd like to know if u guys actually make the glass on window for example to be/have 3 or 6 mm of thickness (or whatever) or do you just put a single plane in?!

I've putting a single plane when using vray and other renderers but im not so sure about Octane being unbiased and all .

any response, much appreciated.

Depends how much the glas swill be in focus.
Usually people tend to use only a single sided plane for basic reflection.
More computing intensive and realistic is a box (or two planes placed behind) which gives you a nice "shifted reflection" effect.

You also can use a very small bumpmap for the glass because the surface is never 100% even.

Below I used the box method with a very slight bumpmap for the shop windows. The shop interiours are just a texture placed behind my glass.
