Johns Manville Announces Plan to Build Polyiso Production Plant in Texas

DENVER – Wednesday, January 22, 2020 – Johns Manville (JM), a global building and specialty products manufacturer and a Berkshire Hathaway Company, announced today plans to build a polyiso production plant in Hillsboro, Texas. 

“We take great pride in creating and delivering the best products for our customers,” said Mary Rhinehart, President and CEO of Johns Manville. “This expansion south of Dallas/Fort Worth, in an area where construction is surging, will increase availability of our premium products to customers throughout the region.”

JM will begin construction on the new production facility later this year, pending various government approvals, and anticipates the completion in mid-2021. When complete, JM will employ more than 50 people at the new facility.

“There are tremendous growth opportunities in the Southwest for polyiso products,” said Joe Smith, President of JM’s Roofing Systems business. “Three of the 10 largest cities in the country are a short drive from Hillsboro, and some of our largest roofing contractors are located within the service area.”

The Hillsboro plant will manufacture polyiso products including ENRGY 3® roof insulation, ProtectoR® HD high density cover board, AP® Foil Faced Foam sheathing and GoBoard® tile backer. These polyiso products are preferred in the market due to their high R-value per inch and the lightweight strength and durability they offer for several building applications. 

“We are excited to build in an area close to our customers and where we can hire good people into the JM family to help our customers be successful,” said Matt Sayer, Polyiso and Boards Product Manager for JM. “Johns Manville will be well-positioned with this expansion to increase product supply to meet the growing demand from our customers.”

Local officials welcomed JM’s decision to expand in Hillsboro.

“Johns Manville is an important addition to the manufacturing and industrial base in Hillsboro,” said Hillsboro City Manager Frank Johnson. “Johns Manville has a long-term stable national and international presence and is known to be a good corporate citizen. We are excited to have them become part of our community.”
