Glazing contractor Custom Enclosure Solutions (CES) worked closely with general contractor Skanska USA to ensure the window wall installation met aesthetic and performance goals, while staying on schedule and within budget.

While the use of a curtainwall was part of the hotel’s original plan, YKK AP was able to customize its YWW 50T to fit the project’s requirements. This 5-inch-deep window wall systems with slab edge cover mirrors the look of curtainwall from a building’s exterior, while providing high thermal and acoustical performance at a lower cost.

Helping save additional time, labor, staging and costs in the field, Technoform’s thermal barrier contributed to a simplified installation of YKK AP’s pre-glazed YWW 50T Window Wall. Technoform supplied three different, standard profiles, which were manufactured in Ohio using its PA 66 polyamide material.

For the inside glazing, YKK AP used Technoform’s 14.6mm flat thermal barrier and, for the slab edge, 14.8mm profiles both flat and hollow shaped were incorporated.

The primary benefit of Technoform’s thermal barrier over pour-and-debridge is it gives us the opportunity to use dual-color finish and also allows flexibility in channel depth. It is the preferred solution by our product engineers when they need to tweak a system.

With the window wall and methodology approved, YKK AP factory-fabricated and shipped the pre-glazed window wall sections to CES at the JW Marriott Nashville jobsite. Working from inside the building, CES quickly and safely installed each unit. After the units are sealed in place, the improved performance and durability of the MegaTherm aluminum framing system with Technoform’s polyamide thermal barrier reduces heat transfer and condensation. High thermal performance assists the hotel owner in conserving energy use and associated expenses.

Lowering condensation also lessens the potential for mold and mildew. Keeping hotel guests comfortable and healthy increases the likelihood of repeat and referred business.

Along with praise from its guests, the JW Marriott Nashville project also earned recognition from the Architectural Products 2019 Product Innovation Awards and has been featured in commARCH magazine. Adding to the compliments, Smallwood’s principal, Michael G. Murphy, AIA, LEED AP BD+C, described the project as “a successful addition to the city of Nashville. I think it will be well received for many, many years in the future.”
