What constitutes sectional insulation?

Sectional insulation is specifically characterized by the use of two half shells, which are designed to encase a pipe. This design allows for effective insulation that can be fitted around the contours of pipes or similar components. The purpose of sectional insulation is to provide thermal protection while also allowing for ease of installation and maintenance since the halves can be opened and closed around the pipe without needing to remove the entire insulation framework.

This method of insulation is particularly advantageous in applications where pipes need frequent inspection or adjustments. The half-shell design not only provides good thermal performance but also helps in containing moisture and preventing energy loss, making it an essential feature in many industrial and HVAC installations. Other options, while they may refer to forms of insulation, do not accurately describe the sectional aspect, as they involve continuous or different configurations that do not allow for the ease of access offered by sectional insulation.
