Highlights of PDM:

• US made product produced in Rock Hill, SC. 
• The original tear-resistant line set in the US since 2008. 
• PDM is now the ONLY line set company in the US that is fully vertically integrated with their own copper mill and proprietary insulation manufactured in-house, giving them full control over the entire manufacturing process. 
• Industry Leading UV Resistance – GelCopper and GelBlack/GelWhite products are the only line sets in the US market to be 3rd party tested and UL Performance Verified for UV resistance and fire/smoke (https://verify.ul.com/verifications/124), with a 5-year warranty against premature UV degradation. 
• Superior R-Value compared to competitive insulation of similar thickness - R4 insulation value with ½” insulation, up to R9.0 with thicker insulation. 
• Proprietary, in-house insulation manufacturing process allows for little to no gap between copper and insulation, reducing opportunity for moisture build up, pitting, and formicary corrosion.
