House mice (Mus musculus) were introduced into 10, 10·2 cm thick insulated panels and provided unlimited food and water for 6 months. Mouse populations increased three- to four-fold inside the insulated panels. Aluminum foil vapor barriers were severely damaged by mice and in all cases, reduced to less than half of their original mass. All of the insulation materials tested (insulation board, fiberglass batt, rockwool, beadboard and vermiculite) sustained significant levels of damage (p < 0·01) as measured by increased thermal conductance. Researchers have yet to discover an insulative material that is not susceptible to house mouse damage.
