UV Resistant Non-Adhesive Wrap
The International Energy Conservation Code (IECC) mandates a UV-resistant, non-adhesive wrap for linesets, because deteriorating lineset insulation is an air conditioning efficiency issue.
IECC: Any insulated piping in areas exposed to weather, such as refrigerant piping associated with a split system air conditioner, is required to be further protected from exposure to sunlight, moisture, and wind—all of which can damage the insulation materials over time. This protection must shield the insulation from solar radiation. The 2012 IECC prohibits the use of adhesive tapes as shielding.
