Tempered glass thickness for large picture windows

Hi,
We're replacing the glass in a series of 3 picture windows in our living room. Each pane is 36" x 72". The lower sill is 10" up from the living room floor. The first window is 6" from an exterior door and each pane is separated from the next by 4". They are wood framed windows, held in place by wood trim. They are currently 3/8" annealed glass that we'd like to replace with tempered glass. Are there guidelines I should follow to determine the appropriate thickness for the tempered glass based on the size and location of windows?
Thanks for your help!

They are all required to be tempered due to their proximity to the floor. If you know for a fact that the glass is really 3/8" then you can get the IGU ordered that thickness, or perhaps a hair larger, if the glass has a wooden glazing strip that will allow for some adjustment in glass thickness. Many Andersen windows had IGUs that were 3/8" thick.

Are you sure that the thickness is 3/8"? Most single pane picture windows were glazed with 1/4". The thinest tempered IGU in that size will be 5/8" using 2 pieces of 1/8" glass and 3/8" air space. You would have to change the molding to make up for the greater thickness.
