I found it very difficult to find WHITE rope caulk. This is one of the few companies that make it. It's easy to use, pliable, and pretty much mistake proof.

I had wind coming in all around my window. It didn't seal very tight. I use this caulking and now I have no one coming in and my room is so much warmer.

great product to stop window leaks

used inside house on leaking horizontal double hung window joint where lock is ( old vinyl windows) works great, easy to use full width needed for this use, designed to pull apart into 1/8 inch wide strips which would not have filled gaps. No odor, easy to reposition, looks better than tape I have been using, and doesnt leave a sticky residue, plus if I had to open the window in case of fire easy to remove quickly. I used 6 boxes and this is a great price.
