Insulate exposed pipes with foam sleeves or fiberglass wrap

5

Wrapping exposed pipes in foam sleeves or fiberglass insulation creates a thermal barrier that slows heat loss and keeps pipe temperatures above freezing. This is the most effective long-term defense for pipes in unheated spaces.

Steps

  1. Identify all pipes in basements, crawl spaces, attics, garages, and along exterior walls.
  2. Measure pipe diameter and length to purchase the correct size insulation.
  3. Cut insulation to length with a utility knife or scissors.
  4. Fit sleeves snugly around each pipe, leaving no gaps at bends or joints.
  5. Seal all seams and joints with duct tape or cable ties to lock insulation in place.

Tips

  • Self-sealing foam sleeves are fastest for straight runs; use fiberglass wrap for tight bends.
  • Install insulated faucet covers on outdoor hose bibs before the first freeze.
  • Inspect insulation annually and replace any sections that are compressed or water-damaged.
