ABSTRACT:
This invention relates to the field of packaging and fuel saving devices and to articles and methods therefor. One embodiment comprises a shipping container for unitized attic stairs. The container is made from rigid plastic foam material which has good thermal insulating characteristics and is so dimensioned as to fit snugly on the peripheral frame of the stair unit after it has been installed. As such, it provides a removeable thermal barrier for the stair-well between an attic and the living quarters of a home. Other embodiments include a matching container member made from similar material which may be utilized in conjunction with the first member so as to further enhance the fuel saving characteristics of the finished installation.
