The Frost King CF55 is a foil-backed natural cotton wrap for insulating HVAC ducts. Its selling point is the "No Itch" cotton, which installs without gloves, goggles or a mask, unlike fiberglass wrap. It adds R-4 and carries a Class A fire rating, and the cotton layer also cushions ducts and damps vibration. R-4 is modest next to thicker fiberglass or foil-bubble wraps, so it suits exposed ducts in mild climates, vibration and noise control, and quick retrofits more than deep cold-weather duct runs.
