A decorative line cover, often called Slimduct, is a PVC housing used to hide and protect the copper line sets on the outside of your home. These covers give your installation a professional, "finished" look by concealing the white insulation and black wires. Beyond aesthetics, they protect the insulation from UV rays, which can cause it to crack and peel over time. Our 12ft PVC Decorative Line Set Kits come with all the elbows and joints needed to follow the contours of your house. We also offer specialized Black Decorative Line Set Covers for a more modern appearance. These covers are paintable, allowing you to match them perfectly to your home's exterior color. They are an essential part of any high-quality Wall Mount or Multi-Zone installation. Investing in a cover kit today can prevent costly insulation repairs several years down the road. It keeps your property's curb appeal high while shielding your investment from the elements.
