Blanketing

Blanketing is the act of covering an object or area with a layer of material to create an insulating, protective, or isolating barrier. The term is used across fields to describe both natural phenomena and engineering practices that involve forming a continuous outer layer described as a blanket.

In meteorology and climatology, a blanket refers to a widespread layer of clouds, fog, or smog that envelops a region, reducing radiation exchange and affecting visibility and temperature. Snow cover can also be described as a "blanket" that insulates soil and crops.

In agriculture and livestock management, blanketing often means placing a warm covering on animals in cold weather to conserve body heat and reduce energy expenditure. Blankets and heaters are common in farms and barns; greenhouse and horticulture use thermal blankets or row covers to protect plants from cold snaps.

In industrial contexts, blanketing refers to creating a protective atmosphere around a process or material. A blanketing gas, typically inert or reducing, is used to shield molten metal during welding or casting and to limit oxidation and contamination. Blankets may also refer to protective covers used to insulate equipment, prevent contamination, or control moisture in storage and handling.

Blanketing considerations include climate, welfare, energy efficiency, safety, and cost. Proper selection of materials, thickness, and coverage is essential to achieve the intended insulating or protective effect.
