Improper installation of insulation and vapor barriers can significantly compromise the performance of refrigeration piping. Gaps, voids, or wrinkles in the insulation can create pathways for heat transfer, reducing the overall efficiency of the system. Similarly, improperly installed vapor barriers can allow moisture to penetrate the insulation, leading to condensation formation and subsequent damage. Furthermore, inadequate securing of the insulation and vapor barrier can cause them to shift or dislodge over time, compromising the integrity of the system.
