The YWW 60 XT is designed to meet the most stringent thermal performance requirements. A clean design, fast installation and maximum design versatility make it ideal for mid-to-high rise building applications, particularly in the Northeast region and other cold-weather climates.
The YWW 60 XT features a U-factor of 0.36 BTU/HR/SF with a COG of 0.29 with standard one-inch glass. Thermal performance is unmatched thanks to 40 mm polyamide isostruts, along with YKK AP’s patented ThermaBond Plus® technology, a pour and debridge system which enhances energy savings, and a patented process to prevent dry shrinkage.
Rather than working to achieve LEED certification through using higher performing glass and fillers, YKK AP developed the framing system itself for this product to perform in markets with extreme cold temperatures. From incredibly high thermal performance, the ability to handle higher structural loads, and taller spans of glass (up to 12-foot mullion spans), to a more seamless aesthetic, the YWW 60 XT will support the evolving needs of customers and the industry for years to come.
