Duck brand rope caulk is putty on a roll. Apply it around edges of windows to reduce uncontrolled air infiltration and exfiltration (conditioned indoor air escaping), help reduce moisture condensation, and to seal against dust, dirt, and insects.

Install simply by pressing it into place with your fingers. Easily applied, self-adhering, yet easy to remove. Rope caulk is an especially good option for apartment dwellers.

One roll has 35 linear feet of caulking rope, which is usually suitable for sealing 2 average-sized windows.

Gray color.

Made in the USA.
