About Teknisk Isolering

Teknisk Isolering AS is the result of a merger between three strong players in the insulation industry: Trøndelag Isolering, Isomerk, and Ranbergs Isolering. Together, we bring over 50 years of experience, evolving from a focus on marine insulation to becoming a leading provider for building, industrial, and maritime sectors

Facts about TI

Our origins

Trøndelag Isolering was founded in 1996 following the closure of a branch office of Rheinhold & Mahla in Trondheim. Originally part of a German company known for industrial and marine insulation, the Trondheim operation became independent and focused on local service

The founders, Henning and Harald Andreas Otnes, acquired Trøndelag Isolering in 2015, growing it into a key player in services like pipe insulation, mantling, fire protection for ducts, and custom insulation blankets
