Suppose an explosion went off near a building, big enough that it could potentially break the windows on all 4 sides but not destroy the frame of the building. Would all the windows break, or just the ones facing the explosion? Would glass from the window on the side of the building furthest from the explosion shatter into the building or away from the explosion? My thought is that the explosion would shatter all the windows and push the glass from them into the building, even for the back window where it would be flying towards the explosion, because the windows are going to be pushed into the lower pressure inside the building. I'm not sure whether the the pressure in the building would increase first and blow out the back window, or if the lag of pressurizing the building would take long enough that the furthest window could be forced into the remaining low pressure. Now that I've written it, it seems like it's going to be a function of window size to building volume. Is there a non-destructive way to figure this out?
