it is cooled the ratio of batt density to batt thickness generally dictates whether the fr insulator pad 40 is a high loft batt or a densified batt for purposes herein a densified energy absorbing layer has a ratio of weight in ounces per square foot to thickness in inches greater than about 2 to 1 for example a fiber batt that is one foot wide one foot long one inch thick and has a weight of three ounces is defined herein as a densified fiber batt in an embodiment such densified fr insulator pads 40 has a density greater than about 1 5 pounds per cubic foot pcf conversely an fr insulator pad 40 having a ratio of weight to thickness of less than about 2 to 1 and or a density less than about 1 5 pcf are defined herein as high loft batts for example a fiber batt that is one foot wide one foot long one inch thick and has a weight of one ounce is defined herein as a high loft fiber batt the fr insulator pad 40 may also be used for may other applications for example the fr insulator pad 40 may be incorporated into residential or commercial furniture to maintain the separation between the furniture spring assembly and the other furniture components the fr insulator pad 40 may also be incorporated into vehicle or aircraft seats to maintain the separation between the seat spring assembly and the.
