According to ASCE 7-98, section 6.5.9.3, it says that glazing in the lower 60 ft. of buildings shall be impact resistant glazing, or such glazing that receives positive external pressure shall be assumed to be openings.
My question: in an area that is NOT a wind bourne debris region, do you have to consider non-impact resistant glazing as openings? Since section 6.5.9.3 only specifically requires glazing in wind bourne debris areas to be impact resistant, I imply that for areas that are NOT wind bourne debris areas the glazing does not have have to be impact resitant to avoid being considered an opening.
Here in upstate NY (Albany area), we have V-90mph, and are not a wind bourne dbris area.
