Weather Stripping for Doors&Windows, 196" Self-Adhesive PU Foam Seal Strip - Soundproofing, Insulation, Door Sweep for Interior Doors (Black)

Slider windows can be a problem, especially when they are single-paned in keeping out the heat and cold. I decided to use this product to see if it would help. Easy to install, they seem to seal the windows well.

This is a basic foam weather strip intended for light-duty use. It has adhesive on only part of one edge (not full-width), which makes it a bit less substantial than higher-end options. I used it to reinforce existing weatherstripping where I could see light coming through, and it did a good job sealing those gaps and keeping bugs out. The backing was somewhat difficult to remove, and the limited adhesive coverage means it may not hold as firmly over time, especially with frequent door use. That said, for quick fixes and minor gaps, it's an easy and effective solution. Best used as a supplement rather than a primary seal. I have circled the installed strip in my screenshot.
