01.080.0301 Base of Wall | Adhered Brick Veneer, Steel Stud Backing, Lath & Scratch Coat
 
This detail illustrates a base of wall condition for adhered brick veneer over light gauge metal framing. A continuous air/moisture/vapor barrier (WRB) over the sheathing provides resistance to air and moisture. Continuous insulation outside the sheathing provides thermal control, and may be supplemented with additional insulation in the stud cavity. Used as a rainscreen device, the drainage mat with protective filter fabric allows moisture to escape the wall via the corrosion resistant perforated weep screed at the horizontal termination. The WRB is applied over the weep screed in shingle fashion. A self-furring lath embedded in a scratch coat of mortar reinforces the veneer system. The veneer is adhered to the reinforced scratch coat with a bond coat of polymer modified mortar. The joints between the units may be pointed in using a masonry mortar.

10.030.0633 Lintel rebuild | Terra cotta, extruded

This detail illustrates a modern rebuild strategy for replacing existing architectural terra cotta (TC) lintel, soffit, and accessory units around window openings. The existing TC is replaced with new extruded TC units, installed not filled, with weep holes at the underside of each overhanging unit; each secured with new stainless-steel anchorage. In restoring and rebuilding these types of historic wall systems, moisture mitigation is critical to their long-term preservation and performance. Moisture management measures in this detail include horizontal skyward-facing joint treatment of sealant or lead T-caps, and an integrated flashing system installed to protect existing structural steel. The flashing system includes a self-adhering flashing with ends dams secured by a termination bar with continuous sealant, a stainless-steel drip edge, and weeps in the vertical joints. Accessible existing structural steel is also protected by cleaning and coating with a corrosion-inhibiting co

10.030.0433 Sill and mullion rebuild | Terra cotta, extruded

This detail illustrates a modern rebuild strategy for replacing existing architectural terra cotta (TC) sill, mullion, and accessory units around window openings. The existing TC is replaced with new extruded TC units, installed not filled, with weep holes at the underside of each overhanging unit; each secured with new stainless-steel anchorage. In restoring and rebuilding these types of historic wall systems, moisture mitigation is critical to their long-term preservation and performance. Moisture management measures in this detail include horizontal skyward-facing joint treatment of sealant or lead T-caps, and an integrated flashing system beneath the sill. The flashing system includes a self-adhering flashing with ends dams secured by a termination bar with continuous sealant, a stainless-steel drip edge, and weeps in the vertical joints. The existing structural steel supports are also protected by cleaning and coating with a corrosion-inhibiting coating. These TC rebuild details

04.030.0202 Dimension stone wall, interior | Wire ties and molding plaster

     04.030.0202 Dimension stone wall, interior | Wire ties and molding plaster This detail shows 2 cm (3/4 in.) thick dimension stone anchored to an interior wall substrate with anchors of 8-gauge  (0.1285”) copper or stainless steel wire ties encapsulated by molding plaster at the perimeter of each stone panel. The wire is fitted into slightly oversized holes in edges of the stone panels, with wood plugs filling the space around the wire. The wire anchors are sized and spaced per empirical design and are fastened to the concrete masonry backing via holes cut into the block, also filled with plaster or rapid-curing cementitious material. Joints between the panels may be finished with compatible sealant and backer rod (not shown for clarity). This detail shall not be used for construction without the approval of a licensed design professional. The person using this detail shall be responsible for its complete design and proper application.
