We spent 27 hours on research, videography, and editing, to review the top choices for this wiki. Good for heat retention in the winter and for preventing gain in the summer, foil insulation can be an effective means of reducing radiant heat transfer across open spaces, such as the attic or basement, and thus reducing energy costs. These best-selling options incorporate reflective materials on bubble or foam wrap, are designed to resist fire and moisture, and can be used indoors or outdoors. When users buy our independently chosen editorial picks, we may earn commissions to support our work. Skip to the best foil insulation on Amazon.
