SK Capital Partners has completed the sale of Isolatek International, a century-old leader in passive fireproofing technologies, to Catchment Capital, marking the end of a focused three-year ownership period aimed at reshaping the business for growth.

 

Isolatek, founded in 1875 and based in Stanhope, New Jersey, is a key supplier of proprietary fireproofing systems used in data centers, advanced manufacturing sites, institutional buildings, and commercial infrastructure. The company has long been known for its technical performance, regulatory compliance, and installation support across complex construction environments.

 

Under SK Capital’s ownership, Isolatek expanded its product portfolio, pushed into higher-growth end markets, and strengthened its technical capabilities through both internal investment and strategic acquisitions.

 

“It has been a privilege to partner with Mike Harvey and the Isolatek team over nearly three years of significant transformation and growth,” said Jon Borell, Managing Director at SK Capital. 

 

“Together, we deepened the Company’s technical leadership, expanded into new markets, and built a more resilient and competitive business. SK Capital congratulates the Isolatek and Catchment teams on this milestone transaction.”

 

The firm highlighted targeted acquisitions and new product development as central to its strategy, including the purchase of assets from Albi Protective Coatings and the launch of FireSolve® SB.

 

“Through several strategic initiatives, including the acquisition of certain assets of Albi Protective Coatings and the launch of FireSolve SB, we strengthened Isolatek’s product portfolio and accelerated the Company’s growth trajectory,” said Booey Ghani, Principal at SK Capital. 

 

“We are proud of what Mike and the entire Isolatek organization accomplished together with our team and wish them continued success as they begin this next chapter with Catchment.”

 

Isolatek CEO Mike Harvey said the partnership helped accelerate the company’s evolution and customer impact.

 

“This transaction marks an exciting new chapter for Isolatek,” said Mike Harvey, CEO of Isolatek. “Our partnership with SK Capital enabled us to expand our capabilities and deliver exceptional value to customers. I am proud of what our team has accomplished and look forward to building on that momentum with Catchment.”
