Wind Mit Scenario 1 asked how to classify the openings of this home with the garage door having glazing as shown.
Using the same information as posted in Wind Mit Scenario 1 – This time assume **THAT THERE IS NO GLAZING IN THE OVERHEAD GARAGE DOOR **(even though it is shown in the pictures)
How would you classify the “Opening Protection” ?
Does form 1802 provide a clear choice for this scenario?
facts are as follows:
All windows had storm protection in the form of panels. Assume all storm panels had Miami Dade County NOA (9 lbs).
The garage door did not have any additional storm protection. Assume garage door is original 1986 construction.
The garage door was as per photos (except assume no glazing for this scenario).
I would not check D because the door is not fully protected. The door has no rating that is listed on the form. But all of the glazed openings have been protected with an approved product. That is why I would select E.
It is my understanding that if you select A, B, C or D then there are no other options that apply. I could be mistaken and welcome others opinions.
If all the glazed and unglazed openings were fully protected with Large missile - 9lb, ‘A’ would be the proper choice. Therefore, since the unglazed garage door does not, ‘E’ would be applicable.
‘E’ is the same as ‘A’ (first box - Large missile 9lb) with the exception of unglazed openings. Therefore, choosing ‘E’ indicates that there are unglazed openings present that do not have verifiable protection.
It would depend on weather the house with the garage door was in the HVHC zone or not. If it is not, the door does not need to be impact rated if it has no glazing. What about a garage door with glazing under the first floor of a house on pilings, for a garage that does not have a door to living space, and all walls for said garage (anything framed under the first floor and attached to the pilings) must be rated breakaway construction?
