  • Great for dryers!
Style: 3M
Let's be real – no one gets giddy about aluminum foil tape. It's like the socks of the home repair world: necessary, but about as exciting as doing taxes. BUT, let me sing the praises of 3M Aluminum Foil Tape 3381, because this ain't your bargain-bin tape, folks. It's got superpowers I never knew aluminum foil could possess ... Why you NEED this tape in your life: HVAC's New Best Friend: Leaky ducts are the air-conditioning world's villain. This tape? It's the superhero! Seals those gaps like nobody's business, saving you on energy bills and the shivers in winter. Who knew some shiny tape could have a bigger financial impact than your stockbroker? The DIY MacGyver: Got a rattle in your car? Wobbly furniture? Hole in your kid's inflatable unicorn pool? Patch it with this tape. It sticks to practically anything, and its durability defies logic. Now if only it could make me handy enough to actually handle bigger home improvement projects... A Cold Weather Warrior: The description says "cold weather," but honestly, this tape is tough as nails year-round. Rain, sleet, heat wave – it doesn't budge. Mother Nature might as well take a coffee break, 'cause this tape won't let her ruin your repairs. Romance Revitalizer? (Seriously, hear me out!): Spouse complaining about squeaky cabinets? A "strategically" placed strip of this tape quiets that hinge better than flowers. Now, THAT'S relationship-saving sorcery right there. Disclaimer: Might not fix ALL domestic disputes. Bonus: Zombie Apocalypse Prep: I mean, have you SEEN the strength of this tape? A makeshift shelter, a weapon patch-up... This tape's versatility could buy you precious time against the undead. Look, when's the last time duct tape did that? Okay, maybe I'm overselling it a tad, but you get the point. This tape is surprisingly impressive. It's made my DIY attempts less disastrous, kept my house's temperature regulated, and might even win me brownie points with the spouse. Now, where did I put that wobbly chair... ... show more

  • Quailing multi-purpose foil tape.
Style: 3M
The tape arrived as described with no issues I bought the tape to use to cover holes at the bottom of my HVAC unit to keep critters from getting into my crawl space and to secure ducting to vents I replaced. It has worked great, and held up, wonderfully even in the rain. It is also handy for any unexpected duct repairs. The tape is a quality product made by 3M that has good thickness and adhesion. I have no complaints as it met my expectations. I would recommend this product to others. ... show more

  • Curls Easily on Ya
Style: 3M
I've used other brands of metal HVAC tape before that were much easier to use. This one has good strong adhesive, but it's real thin so when you pull the paper backing off, the aluminum tape part actually wants to curl up on you really quickly and badly. It sticks to itself and makes a mess. I had to throw some away as a result = waste. I finally learned the trick was to just pull the paper back as you lay it down. So it's usable, but it's a bigger pain than other brands I've used before. I think maybe the other ones I used had adhesive but it was just like duct tape - already on it and you rolled it out as used. I don't remember the paper backing step before. ... show more

  • Thin, thin and thin.
Style: 3M
I thought being 3M, how could I go wrong. First this foil tape is thin, so thin it will tear like paper. It needs to be applied in short sections because if the run is off it will tear apart if you try to lift and adjust. Being so thin it is easy for the tape to arc which starts the problem especially if you’re doing a lateral seam by feel. It will seal ducts if you handle carefully. Update: I upgraded my review. Used to seal HVAC ductwork. It did the job so it was worth the cost. Also being thin if you run into an issues you can easily tear off the part if it so warrants. ... show more
