Project Scope:

Johns Manville’s TPO facility doubled production with an expansion to its existing plant. Thermoplastic polyolefin plant (TPO) is the fastest-growing segment of the roofing membrane market in North America. As demand for these products continued to increase, Johns Manville, (JM) found it was necessary to boost their overall production at their TPO roofing facility to satisfy their customers. IPS was contracted to build a 40,000 sqft warehouse addition to their existing plant. Scope of work included five separate additions that allowed them to add a second production line of their PVC roofing. This allowed JM to double their capacity by 20 percent. They were limited to 5, 8 and 10 foot wide material and now with this second line they are able to make 12 ft. materials for use in commercial and industrial mechanically attached and fully adhered roofing systems. IPS also improved the fire protection system for the entire site and extended their rail spur to off load raw materials. Additional upgrades included process equipment, extruder, vacuum system for new material, cooling towers for processed cooling water lines, electrical service upgrades to feed new lines and 150,000 sq. feet of additional warehouse space.


IPS worked around John Manville’s demanding production schedule that runs 24/7with minimal interruption. IPS worked 10 hour days 5 days a week to accommodate tight working conditions in small spaces and to ensure time deadlines were met.
