Frost King CF1 Cotton Insulation 16x1x48 in

Product Description

The FROST KING CF1 is a no-itch natural cotton multi-purpose insulation designed for fast, tool-free installation in residential and light commercial applications. Made from natural cotton fibers, this insulation eliminates the need for gloves, a face mask, or goggles during handling, making it a safer and more comfortable option compared to traditional fiberglass batt. It measures 16 inches wide by 1 inch thick by 48 inches long and weighs approximately 0.54 pounds per unit. The CF1 can be cut, ripped, or fitted by hand without specialty tools, providing practical flexibility for techs and installers working in tight or irregularly shaped spaces.

The CF1 is suited for residential and light commercial use wherever quick insulation is needed. Common applications include duct wrap, wall cavities, and spot insulation in areas requiring a small or narrow batt. HVAC technicians, plumbers insulating pipe runs, and general contractors handling energy efficiency work will find the no-itch cotton construction useful for overhead and confined-space installs where skin and respiratory irritation from fiberglass is a concern. The 48-inch length and 1-inch thickness make it practical for shallow cavities and duct lining patches.

Installation Notes

Installation is typically performed by HVAC technicians, plumbers, or general contractors. Always power down or shut off the relevant system before accessing ducts or mechanical spaces. No specialty tools are required — the batt can be hand-trimmed or ripped to fit. Follow applicable local building codes for insulation installation in wall cavities and duct systems.
