Abstract
Embodiments disclosed herein include insulation used to insulate elongated members, such a pipe or duct, as examples. The insulation can address a number of features, including but not limited to expansion and compression of insulation material, expansion and compression of the elongated member insulated, and the ability to adapt the insulation for elongated member of different sizes and lengths. In one embodiment, the insulation is comprised of at least one plank comprised of a flexible polymeric foam configured to be wrapped around an elongated member. In order for the insulation to self-adjust to compensate for thermal expansion and contraction of the foam material, the plank is comprised of a plurality of flexible polymeric foam profiles. At least one flexible polymeric foam spacer may also be provided that self-adjusts to compensate for thermal expansion and contraction of the elongated member to prevent or reduce gaps in insulation.
