Hi Lampworketc,
I wanted to get a second opinion about closing in my screen porch, for a vinyl porch enclosure.
Something similar to eze-breeze windows.

Right now the porch is my only place to work, and its been dipping down in the 30's in Memphis. If this keeps up I won't be able to work at all.
It would also be nice to keep the pollen out for the summer.
