Curtainwalls - November 2018

Curtainwalls featured in the November 2018 issue of Metal Construction News.

CRL-U.S. Aluminum’s Series 4500 Curtainwall features the company’s UNIflash System, which sweeps infiltrated water to the exterior and eliminates the need for vinyl flashing. The curtainwall has snap-in component parts and does not use a pressure bar, which facilitates installation. Exterior and interior members are internally joined with a non-conductive, injection-molded thermoplastic connector that provides thermal performance and U-factors to U-0.24. For contemporary, all-glass aesthetics, the 4500SG model can be used for floor-to-ceiling, uninterrupted glass spans.

Oldcastle BuildingEnvelope’s Reliance curtainwall is a thermally broken, zone-glazed, pressure-equalized system. It is available with captured and structural, silicone-glazed, vertical mullions with multiple system depths and glazing infill options. Zone glazing provides air performance and water control. Two infill options are a 1-inch infill system with snap-in adaptors to accommodate 1/4-inch infill for spandrel applications, and a 1/4-inch infill system for maximum utility and versatility. These two infill options have structural, silicone-glazed, vertical options for two-sided applications.

Tubelite's 400SS Series thermal, screw-spline, aluminum-framed curtainwall features a thermally broken system. The system is engineered for glazing in shops or the field for installing on low- to mid-rise buildings. Tubelite's 400SS Series thermal curtainwall's standard 2.5-inch-wide, aluminum-framed system is available in 6-, 7 1/2- and 10-inch depths, and with an aluminum-pressure plate. An optional polyamide-pressure plate meets or exceeds energy codes. Glass is positioned to the 400SS thermal curtainwall's exterior for resistance to rainwater. The 0.5-inch bite securely grips insulated glass or panels of 1-inch thickness. Infill thicknesses from 1/8 inch to 1 5/16 inches also can be accommodated.

YKK AP America’s YHC 300 structural silicone glazed (SSG) curtainwall uses four-sided cassettes for hurricane impact resistance. Shop-glazed cassettes interlock with adapters on the horizontals to create full-width engagement, top and bottom. Framing is stick built on job sites. Vertical sides are togged to the mullions to complete the mechanical attachment. Multiple system depths are available; 1 5/16-inch glazing thickness is standard. Additionally, the YHC 300 SSG has horizontal stack joints for multispan applications.
