Industrial Growth Partners (“IGP”), in partnership with the Hirsh family and management, has acquired Lamart Corporation (“Lamart” or the “Company”).

Founded in 1956 and headquartered in Clifton, NJ,  Lamart is a manufacturer of engineered, coated and laminated flexible materials serving technically demanding applications. With operations in Clifton, NJ, San Diego, CA, and Ensenada, Mexico, Lamart is a critical manufacturer of insulation covering films, acoustic/thermal insulation blankets, high-performance tapes, foil tapes, noise- and vibration-dampening tapes, pressure sensitive films and EMI/RFI shielding laminates. Lamart primarily serves the Aerospace and Defense (A&D) sector, while also serving the space, automotive, construction, energy, medical, industrial, optical and other diverse end markets.

“Our family has spent seven decades building Lamart as a problem solver for our customers,” said Jonathan Hirsh, Chief Executive Officer of Lamart. “Partnering with IGP allows our team and our family to invest in the next phase of Lamart’s growth, while preserving the culture, craftsmanship and customer focus that have always defined Lamart.”

Craig Hirsh, President and Chief Revenue Officer of Lamart, said the timing reflects years of internal groundwork. “We’ve kept a long list of capital investments on the whiteboard for some time, driven by customer demand and market opportunities,” he said. “The investment by IGP enables Lamart to execute on that plan, with people who get how this industry works. We have already hit the ground running with upgrading one of our existing coaters.”
