Installation Instructions for TerraGlas®
Using shop drawings and Stromberg recommendations, TerraGlas terra cotta components should be installed plumb and level to required planes as designed and indicated.
If attachments to a framing system are required, it should be by stainless steel or corrosion resistant screws, adhesive, or hangers in accordance with manufacturer's recommendations. All TerraGlas assemblies should have no deflection greater than L/240.
Large TerraGlas units are usually connected to the structure by means of cast in metal frames constructed of metal studs or metal tubing. Metal studs are generally galvanized per ASTM A525 and conform to ASTM A446. Tubes are ASTM A500 Grade B. These frames are connected to the TerraGlas skin by flex anchors. Large TerraGlas units are erected with similar hoisting equipment to that used to erect precast concrete, except it can be smaller in capacity.
Smaller TerraGlas units may have cast in straps, wires, or inserts as needed. These are typically detailed in the TerraGlas shop drawing process.
Many smaller pieces of TerraGlas are typically installed by hand. Care should be taken when using straps, to not overly stress the TerraGlas units during installation. Usually, TerraGlas units that have steel framing can be picked directly from the steel back up frame. In some cases jigs for lifting the TerraGlas may be needed.
