GlassBuild America kicked off its first day today and exhibitors are beginning to report an improving market since last year.  Fenestration companies in particular are reporting an uptick in sales – as high as 25 percent over last year.

“2014 has been very good, an extremely busy year,” says Seth Patterson, commercial sales manager of Thermal Windows Inc. “The market is back and we’ve had several large projects.”

Patterson says he’s seen the most growth in the high sound transmission class (STC) window segment of the market. He says due to growing metropolitan areas, multi-family residential constructions are not only looking for energy efficiency, but also something that stifles the sounds of the city.

“The higher the [STC rating] number, the better,” Patterson says. “The windows also have really good energy efficiency and meet standards.”

While the STC windows tend to be for commercial construction, WDI Windows sales representative Jack Watts says, “If a [residential] building is over three floors, they have to have commercial performance in order to achieve energy efficiency.” Thus, he says, around 15 percent of the sound mitigation windows manufactured end up being installed in residential buildings.

The show runs through Thursday. Stay tuned to dwmmag.com for the latest show updates.
