ABSTRACT:
A structure for limiting access, such as a storm door, having first and second polymer shells with at least one thereof having side shell portions extending at an angle from a major shell portion with these side shell portions adjoining the other shell, there being a first distribution of magnetic particles positioned between a polymer backing and both the first and second shells. The backing can be fused to the shells to provide a single unit outer structure with the magnetic particle distribution being substantially in the fused portion. These magnetic particles extend in the fused portion around substantially the entirety of a major shell portion. The space between the two shells in that situation can have elongated members enclosed therein which are not fastened to one another by anything extending into such members, and the remainder of this space may be filled with an expanded polymer foam. Another distribution of a different kind of magnetic particles may be positioned at a surface of a major portion of one of the shells.
