Abstract: A stackable shim system. A first shim includes a receiving feature, an attachment feature, and a main portion having a first thickness. A second shim also includes a receiving feature, an attachment feature, and a main portion having a second thickness. The receiving feature of each shim is configured to engage with the attachment feature of the other shim such that either shim can be removably attached to the other to create a stacked shim having a main portion having a thickness that is the sum of the first and second thicknesses. The shims may be conveniently used for taking up space and/or accommodating for irregularities in construction materials.

Abstract: Systems, components, and methods for attaching insulating foam panels to a wall provide additional insulation by virtue of the low thermal conductivity of the foam material of which the panels are made. Structural elements disposed within the panels provide attachment features used for fixing the panels to the wall, and also provide a structural mounting for finishing materials that may be placed on the wall. A clip attaches to the attachment features and is then affixed to the wall. One or more shims may be attached to the clip for accommodating irregularities in the wall. The shims also may be used in a variety of additional applications where accommodation for irregularities in spacing is desired.
