Moisture barrier on garage insulation

A moisture barrier on garage insulation is essential to prevent moisture from infiltrating the insulation material, which can lead to mold growth and reduced insulation effectiveness. Typically made from materials like polyethylene sheeting, the barrier is installed facing the interior of the garage to keep humidity and moisture from outside sources at bay. Proper installation ensures that the insulation remains dry and maintains its thermal performance, contributing to better energy efficiency in the garage space.
