Hi
Your list seemed to indicate to me that the glass bricks would be installed in an outside window. Fair enough.
Some time ago I had glass bricks installed professionally by block layers in an inside flight of stairs in a three story commercial building. They looked great, let in tons of light and everyone liked them.
The Fire Brigade made a regular inspection and despite concrete all around, and nothing flammable, they issued an order to remove them as not being two hour fire resistant.
Out they went.
