works great, easy to install

Last time it got super cold I had massive condensation on the window over the doggy door (an insert panel for the sliding glass door). This caused ice dams to form around the doggy door. I got this product to seal the glass and avoid the ice dam issue. I used it before this most recent cold snap, and it worked perfectly! No more ice around the panel!

Excellent Product!!!!!

This product is amazing!!!! The installation is easy. The product is priced at a great value. I need new windows, but cannot afford them at this time, so I use this product interiorly during the winter months. For the last two years, this product has helped to save on my energy bill throughout the cold winter, and held up with no air leakage.

Nothing Better Than Duck Brand!

I always use Duck Brand window insulation every year. The minute you start to seal it with the hair dryer you can feel the temperature change. It keeps all the draft out. The heat doesn't kick on as often. It's easy to use, seals tight like a drum, and it's very durable. I clean mine with Windex a couple times during the winter so it's always as clear as the day I put it on.
