I used these clear vinyl tarps to enclose my porch for the winter. They are great, you cant even see that this photo is a tarp but it is. Let’s see how the winter treats them.

These are the best. Super good quality, love that they go to minus 70 below because I use outside. Nice and thick, will last I'm sure, as this will be my first season so we'll see. Also comes with optional insurance. The clear plastic is really nice and clear so I can still see outside. Strong border.

Very heavy and so far very durable. I bought this as an extra layer for my screened in porch-to protect my plants and still be able to have a view. It is however, not a full 20’ in length.
