You MUST get this product if you have a grow room. If you're having thoughts about using duct tape because you think it's cheaper you can't compare the two, this is far more superior for grow rooms.

HASH(0xa6d923b4) out of 5 stars Nice foil tape. March 25 2012
By Bob T - Published on
Verified Purchase
This is a nice tape. It has a removable backing which makes it easy to work with. The maximum working temperature is 180°F making it marginal for dryer venting. I would recommend using one of the many UL-181 rated tapes such as Scotch 3326 for dryer venting.

HASH(0xa6d92864) out of 5 stars Useful for all kinds of things, strong adhesive Dec 14 2010
By polsci124 - Published on

You can use this tape just about anywhere, even on wood surfaces, as long as you don't mind the fact that it looks like tin foil. The main purpose is for sealing air ducts, which it is very good for, but it is a good all-purpose tape to keep around the house as well. Better than gorilla tape in my opinion, because the adhesive on it will succumb to heat and come off, this kind won't. Maybe the only thing better than this would be the super-sticky foil tape that is for leak repair (looks like chewing gum almost underneath when you try to pull it off).

HASH(0xa704530c) out of 5 stars Make Your Project "FOIL"-Proof!! Feb. 13 2015
By Consumer Doc - Published on

3M has established a fine reputation for making excellent tapes, abrasives and other flat adhesives. This tape is no exception.


1. This is an excllent aluminum alloy foil with a pressure-sensitive adhesive and paper liner. Outstanding adherence in metal to metal
joints such as duct work and reducing joint tolerances between sheet metal and steel.
I used this tape as an insulator connecting a 4" duct hose to a roof vent. The UL 723 rating made it a perfect choice here.

2. Still the market leader in technical specs and performance ratings-Better overall performance compared to Frost King, Duck and
other major retail brands. See the specs below for comparisons.

3. Made in USA and support is not outsourced to 3rd party global call centers. A real plus in my opinion.

4. Technical Support: Outstanding, 3M-Payrolled employees take your calls and continue to provide outstanding tech support in instances
where customer service support cannot properly address these inquiries.


1. Cost: Value: Budget-sensitive consumers will not be pleased that 3M products have skyrocketed in price relative to their major market competitors. Competing brands still remain up to 44% cheaper yet provide nearly similar performance metrics depending on the application.

2. Customer Service Phone Support: B- as a grade compared to 3M consumer support from just 5 years ago. Phone reps appear to have resorted to the standard script for addressing most consumer inquiries and have become increasingly bureaucratic making for a less than favorable customer experience.


1. This remains a 5-star product with 4 star support.

2. If the application for your particular project is not critical, check prices from other competitors and use your budget as a guide.
If your project requires the best in materials to prevent water infiltration stick with 3M.

3. Support: If your inquiry has merit and/or is complex, avoid the standard "consumer hotline" and call the corporate offices directly in St. Paul, MN
Direct Phone: (651) 737-6501. Request a call back from senior staff or the VP of Consumer Relations. Request their name and contact

HASH(0xa6ea6eb8) out of 5 stars Great tape May 8 2013

This is just aluminum with some glue on the back. It is great for applications where is will be heated or cooled because it stays put. I used this and some duct insulation to make pot cozies for backpacking and it stays put at temps over 200 degrees (e.g. boiled food).
