Most storm doors are for wind and rain not snow.
1/8" tempered glass is not enough for snow according to everyone I talked to. The Home Depot door guy spent 20 minutes trying to get someone at Anderson to see how thick the glass is on their high end storm doors (4000 series) after multiple transfers they came back with 1/2". That sounds like bullet proof glas that Trump might have on his place in NJ. :-)
It's probably the total for a dual pane insulated window. I spent an hour googling around for snow tolerant storm doors with no luck. Dennis said the only thing was a solid door that would not provide ventelation.
Larson Platinum Secure Glass has a KeepSafe® laminated glass which withstands blows from a baseball bat, so would probably hold back snow, But the glass is not removable. https://www.youtube.com/watch?v=MjVNYuUWP6U&ab_channel=TkoProductionsMedia
The only thing I found that provided ventulation and snow resistance was security doors like the ones Sean and Tom found. They would not cave in under snow load, but we'd have to have a way to drain water from the snow that got thru the screen and melted, because of the house heat.
Security doors have one of 3 porous panels along with bars in different decorative patterns. Porus Coverings:
It would still be a gamble in a big dump where the snow between the 2 doors would have time to build up before melting.
I couldn't find any with replaceable solid plates.
One model I found would allow us to easily attach some 3/8" plywood inside the frame covering the porous metal. It had bars in the middle, so we cover the bottom half first and cover the rest later after we got 4 ft of snow.
