Thanks for the question. This front entry does not have window coverings, it is a textured glass in the side window.

If you are thinking about doing black sheers, I would get a long piece and hang it temporarily in the window before commiting to it as a look, as it will darken any natural light coming into the space (assuming that is what you mean by black window coverings?)

Would you know how thick the glass in the door would be. I'm thinking about replacing my front door with a new one because someone broke into the glass of my door. Luckily my dog was near the door when that happened and now I'm wanting to a door with thicker glass. http://www.archdesignwd.com 

I have absolutely no idea! The door and window were in place when we were hired, we just painted the door. Ask a door company that does side lights they recommend for front doors, I am sure you can buy stronger glass.
