What a great idea...

I think this is a wonderful idea, especially for the Bay Area of CA where there is very very few bugs to deal with.

It would allow fresh air, but be strong enough to withstand pets such as cats and dogs. An issue with screens on patio doors are that they are not structurally strong enough to deal with a dog running into it.

This door would solve that issue...
