SPIDA visits Johns Manville plant in Dallas, Texas

Last month, members of the Spiral Duct Manufacturers Association (SPIDA) were in Dallas, Texas, for the organization's annual meeting. In conjunction with the meeting, Brennan Hall of Johns Manville, hosted a tour of the company's Cleburne, Texas, plant.

The 415,000-square-foot manufacturing facility is where fiberglass duct liner, duct board and Spiracoustic Plus round duct liner are produced and includes a 280,000-square-foot warehousing facility.

SPIDA is a nonprofit organization promoting the use of spiral-seamed round and flat-oval duct through research and education from some of the leading experts in the spiral duct industry. Its members — which include duct manufacturers, suppliers and installers — represent residential, industrial and commercial markets from all over the country.
