A year later, Rmax opened a second manufacturing facility in Greer, S.C., and in 1981, a third plant was opened in Fernley, Nev.

Mr. and Ms. Hart have been the active owners of the company since its inception, making Rmax the longest-standing, privately held polyiso insulation manufacturer in the nation. Mr. Hart has always been Chairman of Rmax, and his spouse, Linda W. Hart, has served as the company's Vice Chairman since 1990.

“Rmax contributions to the industry are many,” said Heiskell, who noted the company's pivotal role in founding the Polyisocyanurate Insulation Manufacturers Association in 1987, under former Rmax President, Richard W. Griner, as a major milestone. “Our commitment to the industry and our customers endures, as we have recently introduced our ECOMAXci Wall Solution to provide continuous insulation for commercial buildings, and our Thermasheath-SI structural insulation solution for residential applications during the past year.”

Over the years, Rmax has engineered many building science breakthroughs, including structural roofing insulation products, green blowing agents and, more recently, its building envelope system insulation solutions. The company's technical expertise, customer service, commitment to sustainability and proven track record of supplying quality insulation and building solutions for all types of structures is renowned throughout the industry. Rmax operates sales offices coast-to-coast, ready to serve the needs of its evolving and expanding customer base.
