Which is better for a porch or patio enclosure?

The Sigman. It is 20-mil clear vinyl with UV resistance and grommets about every 2 feet, and it is designed for vertical enclosure curtains. The SHADEPLUS is a thin polyethylene cover, not an enclosure panel.

Is the Sigman worth about six times the price?

If you need clarity and outdoor durability, yes. The Sigman is $115.97 at MyTarp as of November 3, 2026, versus $20.40 for the SHADEPLUS as of October 31, 2026. The SHADEPLUS has no written warranty and a thinner sheet.

Which lasts longer outdoors?

The Sigman is the safer bet. It is thicker vinyl with stated UV resistance. The SHADEPLUS claims only 3% treated UV protection and carries no written warranty.

Can I use either one as a roof cover?

No for the Sigman; the maker says it is not for horizontal, load-bearing use where water or snow can collect. The SHADEPLUS is a general waterproof cover, but 14-mil polyethylene is not a roofing material.

Which is easier to install alone?

The SHADEPLUS, at 4 lb. Sigman buyers say the 20-mil tarp is heavy and cumbersome to set up solo, though its 2-foot grommet spacing gives more tie-down points.

Does the Sigman really stay clear?

Buyers rate it 4.8 out of 5 and say it is very clear and does not block the view. Some report creases from folding that caused tiny cracks, so ask for it rolled rather than folded if you can.

Sigman 8' x 10' Clear Tarp, 20-MIL Clear Vinyl vs SHADEPLUS Clear Tarp 8'x20' 15MIL

Buy the Sigman if you need a clear panel for a porch, deck or patio enclosure that has to stay see-through and hold up outdoors. Buy the SHADEPLUS only if you want a cheap, large 8'x20' cover for light weather protection and don't need optical clarity or long life. The Sigman is $115.97 at MyTarp as of November 3, 2026, and the SHADEPLUS last sold for $20.40 on October 31, 2026. That is roughly a six-fold price gap, and the Sigman is the only one of the two built for enclosure use.
