Coldspring Integrates Stone Panels International Operations
COLD SPRING, Minn. – Coldspring announced today that Stone Panels International (SPI) is now an official division of the company.
SPI, based in Marble Falls, Texas, produces StoneLite® lightweight natural-stone panels for cladding and other special purposes where material mass can be an issue.

Coldspring, the longtime quarrier and fabricator of natural stone and bronze, acquired SPI in November 2016. SPI operated as a wholly owned separate entity until now.
This full integration marks a strategic step forward in strengthening service offerings and streamlining operations while maintaining the same quality and innovation. The product line will now be sold exclusively through Coldspring as StoneLite® by Coldspring.
“We are excited to bring Stone Panels International fully into the Coldspring family,” said Greg Flint, Coldspring president/chief operations officer. “This transition allows us to continue delivering the industry-leading StoneLite® lightweight honeycomb natural stone panels with the same expertise and commitment to excellence that our customers expect.
“With this integration, we are well-positioned to expand our capabilities, increase efficiencies, and enhance customer service.”
The StoneLite® manufacturing facility will continue to operate at its current location in Marble Falls. Existing SPI contacts will remain in place to ensure continuity and personalized service. s: All future contracts, purchase orders, and payments will now be made through Coldspring.
The lightweight natural-stone panel concept was developed in Ireland in the 1960s and brought to the United States in the 1970s. SPI operated from several locations in Texas and went through several ownerships by several private-equity groups before Coldspring acquired the exclusive rights to the patented manufacturing process and trademarks of the StoneLite® system in November 2016.
