Abstract: Notched, surface-mounted wall anchors and anchoring systems employing the same are disclosed. The anchor is a notched, folded sheetmetal construct utilizable with various wire formative veneer ties. The depth of the notch is greater than the combined thickness of the wallboard and the waterproofing layer. Various embodiments show wall anchor configurations with suitable veneer ties and differing sheathing arrangements. The notches, upon surface-mounting of the wall anchor, form small wells in the portion of the notch extending into the insulation, which wells entrain water vapor, condensate and water, and relieve the same from being driven into the wallboard.

Abstract: A seismic construction system for a cavity wall is disclosed. The system is shown in three exemplary applications—a masonry backup wall with ladder- or truss-type reinforcement cooperating with a snap-in wire tie; a masonry backup wall with ladder- or truss-type reinforcement with a high-span wall anchor cooperating with a low-profile, snap-in wire tie; and a drywall backup wall with internal insulation, a sheetmetal wall anchor, and snap-in wire ties. The snap-in wire ties accommodate a continuous reinforcing wire for the outer wythe, which reinforcing wire snaps into the wire housings therefor with a predetermined force. With the interconnected wall and veneer anchors and the respective reinforcing elements a seismic construct is formed.

Abstract: A high-span anchoring system is described for a cavity wall incorporating a wall reinforcement combined with a wall tie which together serve a wall construct having a larger-than-normal cavity. Further the various embodiments combine wire formatives which are compressively reduced in height by the cold-working thereof. Among the embodiments is a veneer anchoring system with a low-profile wall tie for use in a heavily insulated wall. The compressively reduced in height wall anchors protrude into the cavity through the seams, between insulation strips, which seams seal thereabout and maintain the integrity of the insulation by minimizing air leakage. Further, the eye wires extend across the insulation into the cavity between the wythes, and each accommodates the threading thereinto of a wire facing anchor or wall tie with either a pintle inserted through the eye or the open end of the veneer tie. The veneer tie is then positioned so that the insertion end is embedded in the facing wall.

Abstract: A backer rod adapted for insertion into a construction joint having a polymeric foam body of closed-cell construction and a foraminous skin with both open and closed cells. The backer rod, when compressively inserted into a construction joint, is impervious to hot and cold sealants alike and maintains the seal integrity during the extremes of expansion and contraction. The backer rod is usable over the temperature range of ?70 to 450 degrees Fahrenheit. The backer rod hereof is a continuously extruded closed-cell foam body that is degassed by a secondary extrusion. The skin portion is formed by heat treating the exterior of the polymeric foam body so as to create microperforations therein.

Abstract: A metal-foil-containing flashing laminate is disclosed which laminate is for flashing cavity walls. The laminate has at least one layer of an elastomeric composite over which is placed a hot melt adhesive layer, a metal foil lamina, and another hot melt adhesive layer. In this embodiment the metal foil is encapsulated by the adhesive layers. In application this laminate used with a release paper forms a peel-and-stick product and is suitable for surface mounting. Also to the basic laminate an additional elastomeric composite layer is placed above the metal foil lamina sandwiching the foil and forming a through-wall mountable product. A termination bar for use with surface mounted flashing with a polymeric foam coating is also disclosed. The peel-and-stick flashing may be lap-mounted at the seams between adjacent strips without caulks or sealants.

Abstract: Wall anchor constructs and anchoring systems employing the same are disclosed. Each anchor is a sheetmetal construct utilizable with various wire formative veneer ties. In the wall anchor structures, the junctures of the legs and the base of the wall anchor are located inboard from the periphery of the wall anchor base. With the surfaces of the leg base and the anchor base coplanar, the leg insertion point is, upon installation, sealed thereby. This sealing precludes penetration of air, Moisture, and water vapor into the wall structure. Various embodiments showing wall anchor configurations with suitable veneer ties are provided.

Abstract: A metal foil/scrim flashing laminate is disclosed, which laminate is for flashing cavity walls. The laminate has at least one layer of a modified polymeric coating which is disposed by roll coating onto the central metal foil. In all the embodiments, the metal foil lamina is sandwiched between either layers of the modified polymeric coating or between a coating layer and a hot melt adhesive layer. In application the laminates are used with a release paper to form a peel-and-stick product and is suitable for surface mounting. An embodiment of the metal foil/scrim flashing with adhesive is shown for field installation with sealants and mystics.

Abstract: A folded wall anchor and an anchoring system employing the same are disclosed. The anchor is a folded sheetmetal construct utilizable with various wire formative veneer ties. The folded wall tie enables the junctures of the legs and the base of the wall anchor to be located inboard from the periphery of the wall anchor. Upon installation with the surfaces of the enfolded leg and of the base coplanar, the leg insertion point is sealed thereby. This sealing precludes penetration of air, moisture, and water vapor into the wall structure. Various embodiments showing wall anchor configurations with suitable veneer ties are provided.

Abstract: Side-welded anchor and reinforcement devices for a cavity wall are disclosed. The devices are combined with interlocking veneer anchors, and with veneer reinforcements to form unique anchoring systems. The components of each system are structured from reinforcing wire and wire formatives, including as part thereof truss or ladder mesh reinforcements, and provide wire-to-wire connections therebetween. Beyond the portions of the wire formatives inserted in the backup wall, the wire formatives are reduced in height by cold-working thereof. The combined side-welded wall anchor and reinforcement devices are compressively reduced in height for spanning insulation mounted on the exterior of the backup wall. The low-profile portions are disposed between thick strips of insulation and maintain integrity thereof by preventing air leakage.

Abstract: High-span and high-strength anchors and reinforcement devices for cavity walls combined with interlocking veneer ties are described which utilize reinforcing wire and wire formatives to form facing anchors, truss or ladder reinforcements, and wall anchors providing wire-to-wire connections therebetween. These combine wire formatives which are selectively and compressively reduced in height by cold-working. The masonry anchor have eye wires accommodating the threading thereinto of a wire facing anchor or wall tie with either a pintle inserted through the eye or the open end of the wall tie. The wall tie is then positioned so that the insertion end is embedded in the facing wall. The masonry anchor is embedded in a bed joint of the interior wythe. For high-strength applications, specific wire formatives are used which employ materials that benefit from the cold-working of the metal alloys to meet the unusual requirements demanded.

Abstract: A masonry flashing system is disclosed which includes a laminate for flashing cavity walls and a hot melt adhesive composition for coating the surface of the laminate. The adhesive is selected for compatibility with a peel-and-stick installation and, thus, upon pressure activation, when the laminate with hot melt adhesive thereon is pressed against the rough surface of the masonry block, a durable bond is created. The laminate is a polymeric substate formed in part from a mixture of polyvinyl chloride and ethylene acetate carbon monoxide terpolymer and is reinforced by an embedded fibrous mat—either woven or non-woven. The system also includes a stainless steel drip plate with a hot melt adhesive coating. The drip plate adhesive coating enables the installer to accurately position the plate during construction and maintain the alignment thereof. Optionally, a foam layer is placed on the lower surface of the drip plate so as to improve the sealing of the drip plate to the brick veneer.
