Custom windows makers can make them look anyway you want. When I was at COMNAVAIRPAC in the early 1990's the Admiral's conference room which had 4 large windows in it. They had been covered from the inside with metal sheeting to block out radiation during "secret" briefings and had not been opened in 40 years! They had pretty much rotted the wood away AND to make matters worse the building is a federal historic landmark (Naval aviation started there you see). So the designer called in a San Diego company that specials with windows like we needed. It took 2 months to get them made and from the outside they looked exactly like old wooden windows. On the inside they had a set of folding metal "shades" that blocked any listening by spies! If I remember correctly they were $3500 apiece in 1992 dollars.
