Is it Rodent Resistant?
In 1992, the University of Nebraska tested the impacts of mice on 5 other types of insulation (Cellotex, Fiberglass, Rockwall, Styrofoam and Vermiculite). None of those five had any significant impact on the way the mice tunneled and nested. TempShield Insulation is a new product designed with this in mind. TempShield Reflective Bubble Insulation is constructed with tough metalized film and nylon instead of the typical, easy to gnaw through, fiber and foam insulation. See actual study results (PDF)
According to The Ontario Ministry of Agriculture, Food, and Rural Affairs, “Most rodents nest in the insulation of double walls. Block off all entrances into walls and remove all nesting materials.”
According to The University of Nebraska Lincoln Extension Institute of Agriculture and Natural Resources, “Damage to insulation alone may amount to several thousand dollars in only a few years. Energy loss from rodent-damaged buildings results in added cost.”
According to the US Army Center for Health Promotion and Preventative Medicine, “A rodent nest is usually a pile of materials, such as… insulation [and] Styrofoam… under which the rodent lives.”

Disclaimer: No insulation on the market is 100% rodent-proof. Insulation materials alone will not completely deter rodent infestation. The consumer should also properly dispose of garbage, fallen branches, nuts, berries, etc. to prevent easy access to food, and properly seal siding, pipe chases, vents, etc. to prevent easy entry.
