same sense as the building code in that after the installation of the anchoring system there is no change or interference with the insulative properties and concomitantly substantially no change in the air and moisture infiltration characteristics in a related sense prior art sheetmetal anchors have formed a conductive bridge between the wall cavity and the interior of the building here the terms thermal conductivity and thermal conductivity analysis are used to examine this phenomenon and the metal to metal contacts across the inner wythe anchoring systems for cavity walls are used to secure veneer facings to a building and overcome seismic and other forces i e wind shear etc in the past some systems have experienced failure because the forces have been concentrated at substantially a single point here the term pin point loading refers to an anchoring system wherein forces are concentrated at a single point in addition to that which occurs at the facing wythe attention is further drawn to the construction at the exterior surface of the inner or backup wythe here there are two concerns namely maximizing the strength of the securement of the surface mounted wall anchor to the backup wall and as previously discussed minimizing the interference of the anchoring system with the insulation the first concern is addressed using appropriate fasteners such as for mounting to masonry block the properly sized concrete threaded anchors.
