During One of the Coldest Winters Ever, This $25 Insulation Hack Is Saving My Sanity

I love my little NYC apartment. The light that pours through my oversized windows is everything — especially during these long winter days. But this winter? We’re living through one of the coldest on record, and those same gorgeous windows have become my biggest heating nemesis. Drafty breezes sneak through the edges, especially in my bedroom, turning what should be cozy evenings into inventive ways to keep my heating bill low.

I recently saw a TikTok go viral that finally felt like a light at the end of the frigid tunnel. It was all about the Alien Seal Anti-Draft Adhesive InstantInsulation Tape — a simple, peel-and-stick solution to stopping drafts — and I immediately had to add to cart. You can currently get $15 off a $35 purchase with code WELCOME15 at QVC, so if you’re also living somewhere that makes you question whether you should just move to Florida already, this might help your wallet and your windows this winter.

The Alien Seal Anti-Draft Adhesive InstantInsulation Tape is basically what it sounds like: a self-adhesive insulation tape that seals gaps around windows and doors to block cold air and help retain heat. According to QVC, it’s designed specifically to reduce drafts and heat loss. It’s super easy to install, with a sticky backing that adheres right to the frame — no tools or professional help required. It’s also pretty beginner-friendly, specifically aimed to help seal those uneven surfaces and extra small gaps that seem minimal until 50-mile-per-hour winds are seeping in. Basically, it turns those pesky cold breezes into no breeze at all. For someone who’s been waking up freezing and debating whether I should sleep in my bathrobe, this feels like a tiny miracle.

“It worked when the temperature outside was -8°. No pipes froze, and it was comfortable in what was normally drafty doors and windows. I wish now that I had bought more. It definitely helped! Door was also easy to open and close with tape on.” —Redwoman

“Works great. I have a gap in my door that we tried multiple ways to fill, to keep the cold winter air out. Nothing did the job; this does the job!. Super easy to install.” —PJos

I have really drafty windows in my bedroom. Normally we cover them with plastic and listen to the sound of the wind pushing against the plastic [on the] window and hope that it holds. Since we’ve applied the Alien Seal Anti-Draft Adhesive Tape, we’ve been pleased and warm.” —Kriv81
