GD Watermark is a key distributor of K-Flex products. K-Flex elastomeric insulation provides premium, weatherproof protection for copper piping. Engineered for versatility, this flexible foam sleeving is ideal for hot and cold water systems, as well as air conditioning and HVAC lines.

The application of K-Flex protective foam significantly reduces thermal loss. This thermal barrier prevents cold water from warming and ensures hot water reaches bathroom or kitchen faucets efficiently, even when the water heater is located a long distance away. Implementing K-Flex insulation improves system efficiency and reduces energy waste.
