Top 50 Glaziers 2016: The List

Snowbird Hidden Peak Restaurant

LCG Facade installed the entire exterior skin for the Snowbird Hidden Peak Restaurant, at the top of Hidden Peak in Snowbird, Utah. “The project elevation is 11,000 feet, and access was via the Snowbird Tram or a steep mountain double track trail. At that elevation we had to take special precautions to avoid altitude sickness and still work safely and efficiently,” describes Ted Derby, business development manager for LCG. “The mountain sloped off the end of the building with a 70 degree slope. The site conditions changed daily with sun in the morning and rain and snow flurries during the day. High winds slowed or stopped the work nearly every day. The project had a mandatory work stoppage in all lightning storms. … In spite of all the challenges, our crews worked with skill and dedication to complete this unique project on time and within budget.”

The project features 7,625 square feet of high performance, laminated glass fabricated by Northwestern Industries Inc. The insulating glass units consistsof a piece of laminated glass—Optiview with 44 percent gray from Pilkington; a .030 polyvinyl butyral interlayer; and a lite of PPG Industries Solarban clear 70XL—an argon-filled airspace; and a clear, tempered inboard lite. EFCO Corp. supplied the curtain wall system. The company also installed glass handrail for the project, along with 9,650 square feet of composite panels from Swisspearl used in conjunction with a support system from Knight Wall Systems. The architect was GSBS Architects and the general contractor, Layton Construction. Photo by Joe Kalisz, LCG Facades.

The annual Top 50 rankings present what Glass Magazine editors believe to be the United States’ 50 largest contract glazing firms, based on sales volumes. The glazing firms are ranked within nine sales categories.

Information from 49 of the Top 50 comes directly from contract glazing firms or from financial reports from publicly traded parent companies.

We understand the sensitivity of releasing sales figures; however, we do not omit any firms simply because they ask. In cases where a company declines to provide information, we use independent sources to determine its ranking.

If your company belongs on the list, or you would like to update its information, please contact us. It is only with the cooperation of individual companies that Glass Magazine’s Top 50 Glaziers rankings can be as accurate as possible.
