In an ambitious move to reshape the future of energy conservation, the KLINGER Group is pleased to announce the acquisition of the renowned Intertherm company in South Africa, effective from January 1st, 2024. With a rich history since 1997, Intertherm has stood out as a dedicated supplier of thermal and acoustic insulation services pivotal to the energy sector – and a long-term partner of KLINGER South Africa.
Intertherm, with its strong foothold in Gauteng, KwaZulu-Natal, and the Western Cape, amplifies KLINGER South Africa’s expansive network across the southernmost country in Africa. This acquisition promises to make cutting-edge thermal and acoustic insulation solutions more accessible to a wider customer base.
KLINGER South Africa’s bold vision, aspiring to grow the Service division (Engineered Solutions), finds a fitting ally in Intertherm’s specialized offerings.

While Leonard Phelps, the founding pillar of Intertherm, steps into retirement, his son Matthew Phelps steps up, ensuring that the legacy continues. As the newly appointed Business Unit Manager Thermal Insulation at KLINGER South Africa, he is poised to drive the combined entity to new heights. In his words, “We’re on the brink of an insulation revolution.” Intertherm has carved a niche with its capabilities, especially in thermal insulation, catering to temperatures from -212°C to a phenomenal 1600°C. Their acoustic solutions and state-of-the-art fabricated cladding techniques, not to mention their prowess in specialized scaffolding, make them an industry frontrunner.

Christoph Klinger-Lohr, CEO of KLINGER Group, is looking forward to breaking new ground with Intertherm.
Intertherm, now part of KLINGER South Africa, boasts an array of specialized services that set them apart in the industry.
As Intertherm products seamlessly blend into the KLINGER South Africa brand, customers can anticipate a synergized offering that magnifies value, quality, and innovation.
The synergy between KLINGER South Africa and Intertherm is evident in the magnitude of projects they have undertaken. A testament to this collaboration is Intertherm’s recent involvement in landmark projects with notable companies like:
These ventures, ranging from the hot insulation of drying plants to cold insulation vessels, signify not just the scope of work, but the expertise and dedication they bring. The expanded network ensures that quality insulation solutions are just within arm’s reach for customers across the nation. This also means rapid response times, efficient project execution, and a localized understanding of diverse client needs.
Both companies share a common ethos: sustainable growth. The projects they undertake aren’t just about insulation but about energy conservation, about ensuring that businesses operate efficiently while conserving the environment. Hence, the acquisition of Intertherm by KLINGER South Africa isn’t just a business move; it is a statement of intent. It signifies a commitment to lead, innovate, and set new benchmarks in the energy conservation industry. As these two giants come together, one can only expect groundbreaking solutions that will shape the future of the industry.
