The Climaflex Lagging 1/2" x 9mm is designed to control heat loss in your pipes. This helps reduce energy consumption when heating water, which in turn can lower your heating bills and carbon footprint. It also prevents condensation on the pipes and protects them from freezing in cold climates. Suitable for use with steel, copper, and plastic pipework, this product features a closed-cell PE foam that retains heat effectively. The pre-slit design makes it easy to fit, and it's available in a 2m length.
