Equipment, tube, and pipe insulation reduces heat loss or gain, prevents freezing, and controls condensation. These preformed shapes and sheets of insulation come in a range of materials with different resistance properties and benefits to fit the needs of the application. Removable insulation covers temporarily insulate pipe fittings, valves, and other components in a pipe system. Compressed-fiber rope-edge seals push into grooves, seams, and gaps in oven doors or furnaces to reduce thermal loss.
