3M Vent Tape 394, White, 1 in x 36 yd, 4 mil

This is a really neat product. I'm using it on my greenhouse panels to seal up the bottom edge, to keep bugs, dirt and stuff out of the panel. The tape is 1" wide which is just wide enough to leave about 3/8 inch on each side. The tape has enough stick to easy hold and re-position if necessary. The tape tears easily and seems to hold up well during installation. I don't know if it will hold up for the long term but its a great solution to seal up the bottom of the panels. For ease of installation I placed the tape on the open portion of the panel and then folded it over to the two sides. This allows you to lift the tape up and re-position if necessary so that the tape falls evenly on both sides.

Great Value! Cheaper than venting tape from any other source I could find. WAY cheaper than from a greenhouse supply store. I trust the 3m brand for good adhesion and quality product. Seems to work as advertised. I will buy this again when needed.

Minus 1 star because I don't see any reason this tape should cost $30Minus 1 star because it's an absolute pain to work with, and is very fragile.

I bought this to use on the bottom openings on double walled poly sheets for my green house. Definitively wide enough. Seems to stick well even with being a light weight. I've seen some that aren't very breathable due to having so much adhesive, I don't think this will be a problem here. I don't think it will just come off either, it will keep bugs and dust out. Easy to work with.

I waited 3 days for a $25 roll of tape that halted the process of my greenhouse build because this isn't sold locally anywhere. Now 3 days later it's coming off already. What a huge waste of money. This doesn't stick well at all.

Needed it to vent my clear roof panels. So far it's working very well. No moisture, no bugs.Update: After a couple year the bugs, dirt and condensation are all there. Too bad it doesn’t last.

Used this tape to seal the 10mm poly panels in my greenhouse. Product sticks very well and very easy to use on a needed project to prevent dust, bugs water from getting into your panels.

Worked very well for our purposes. Seems to be only supplier for this type of tape. Would order again from this seller
