Which is better for a greenhouse?

Product B's 10 mil vinyl lets more light through and is easier to drape over a frame. Product A's 24 MIL is tougher but blocks and diffuses more light and is stiffer to work with.

Which lasts longer outdoors?

Product A's 24 MIL vinyl should outlast the 10 mil sheet against tears and punctures. Both list UV resistance and a -32 C cold crack rating, so sun and cold are not the deciding factor.

Is the thicker tarp worth the extra cost?

If you hang it as a patio curtain that takes wind and abrasion, yes. For a seasonal greenhouse cover, the lighter 10 mil is usually enough.

Are these really 8 x 20 ft?

Both titles say 8 x 20 ft, but both spec sheets also list 4' x 6' and 10 ft. Confirm the cut size with the seller before ordering.

Can either be used as a patio curtain?

Yes. Both list patio curtain as a top use case, with grommets and heat-welded seams. Product A's heavier vinyl hangs with less flutter in wind.

Do they meet fire codes?

Both list compliance with CPAI-84:1995 Clause 3.2, the common flammability standard for tarps. Check your local code before using either indoors or on a structure.

Both are clear PVC tarps with grommets and heat-welded seams, but the listings disagree with themselves on size and thickness. Product A is titled 8 x 20 ft and 24 MIL, yet its spec sheet also lists 4' x 6' and 10 ft. Product B is titled 8 x 20 ft but 10 mil, with the same 24 MIL spec sheet copied in.
