Reflectix SPW0402512 4-Inch by 25-Feet Spiral Pipe Wrap
Simply spiral Reflectix Pipe Wrap around your pipes, overlapping 1/2-Inch as you go. Securely tape with Reflectix Foil Tape around each end of your wrapped product. This procedure provides an air space that will aid the insulation value. Do not leave any exposed pipe or space where air can enter between the pipe and the wrap.
