Wrapping the pipes in foam insulation can help lower their exposure to the elements, reducing the chance of freezing. Pipe insulation comes in a variety of sizes, and you should be able to install it easily.

Things You Will Need

  • Tape measure
  • Pipe insulation
  • Sharp knife
  • Acrylic or duct tape
  1. Place full sections of insulation around the pipe wherever possible. Butt the ends of the insulation sections together on the pipe.

  2. Pull the plastic strip out of the slit in the pipe insulation to expose the adhesive. Press the sides of the slit together to seal the pipe insulation shut.

  3. Measure and cut sections of pipe insulation to fit where full sections will not. Place the smaller sections on the pipe and seal shut.

  4. Cut sections of pipe insulation at a 45-degree angle and place them over elbows in the water pipe, matching up the angles to cover the elbow. Seal the pipe insulation shut.

  5. Cover all seams and joints with a wrap of acrylic or duct tape.
