Abstract: A sheathing-retention device, for securing sheathing against a wall having at least one protruding wall-tie with a substantially rectangular cross-sectional profile, includes a sheathing-retention device having a sheathing-engagement surface for abutting an exterior surface of the sheathing, and a press-fit type tie holder portion with a channel orthogonally formed with respect to the sheathing-engagement surface, the channel having a substantially rectangular cross-sectional profile approximating that of the wall tie and being dimensionally adapted for snugly fitting around the wall-tie when the sheathing-retention device is urged onto the wall-tie by having at least a portion of the channel with cross-sectional dimensions less than rectangular dimensions of the wall-tie cross-section, the channel extending through both the sheathing-supporting portion and the press-fit type tie holder portion.

Abstract: A method for enclosing a layer of insulation covering a building foundation having a vertical edge, where the layer of insulation has front, back and edge surfaces. The method involves: (1) placing the back surface of the layer of insulation against the foundation such that the edge surface of the insulation is aligned with the edge of the foundation; (2) covering the front surface of the layer of insulation with a first protective cover; and (3) enclosing the edge surface and parts of the front and back surface of the insulation with a second protective cover by positioning a back overlap portion of the second protective cover between the back of the layer of insulation and the foundation and a front overlap portion of the second protective cover between the front of the layer of insulation and the first protective cover, whereby all surfaces of the layer of insulation are enclosed. A system for protecting insulation covering a building foundation is also disclosed.
