Curtainwalls - May 2018

Curtainwalls featured in Metal Architecture's May 2018 issue.

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.

Tubelite’s Series 400T Thermal Curtainwall is a shear-block, outside-glazed, captured curtainwall. Its concealed-fastener joinery creates smooth, monolithic appearances. The 400T Series Thermal Curtainwall has system depths from 6 1/4 inches to 10 1/4 inches. It has a 2 1/2-inch sightline. The curtainwall can be stick-fabricated for field glazing. Optional polyamide pressure plates are available.

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 multi-span applications.
