What Trøndelag Isolering AS does
Trøndelag Isolering AS, now operating as Teknisk Isolering AS following a January 1, 2025 merger with Isomerk AS and Ranbergs Isolering AS, is a Norwegian technical insulation contractor headquartered in Malvik (Trondheim area). The company delivers project-based insulation services across four functional categories — heat, cold, sound/noise, and fire protection — for industrial process equipment, pipes, tanks, valves, flanges, pumps, and maritime installations. Core offerings include technical insulation, custom-made removable insulation pads (isolasjonsputer), prefabricated metal cladding and encapsulation (mantling) in aluminum, stainless steel, galvanized steel, aluzinc, or plastic-coated materials, fire insulation meeting A-60 class requirements, personnel protection insulation, and sound/noise enclosures. Inputs span mineral wool, cellular glass (Foamglas), aerogel, polyurethane foam, and customer-specified materials, with in-house workshop prefabrication using equipment such as the Mabi 3000E evo.
The company serves industrial process companies, food processing facilities (salmon, dairy, marine ingredients), shipyards and maritime clients, energy producers (hydropower, wind, hydrogen, energy centers), and defense/critical infrastructure operators. All employees hold Norwegian trade certificates (fagbrev), and select personnel hold NSM security clearances enabling work on classified defense and critical infrastructure installations — a capability few Norwegian insulation contractors can offer. Notable customers include Boliden Odda (zinc smelter expansion, 50,000+ hours of work), Nordlaks (salmon processing plant at Børøya, contract through 2027), Elkem (silicon production facilities at Thamshavn and Salten), Nidar, Norske Skog, Tine Midt-Norge, Nutrimar, Yara Glomfjord, and TVTrading AS. Customer engagements frequently involve documented outcomes such as up to 90% heat loss reduction on insulated valves and perceived noise reductions from 80dB to 67dB (60%+ reduction).
The business operates a B2B sales-led go-to-market with Key Account Managers using HubSpot CRM, positioning early in customer project planning and tender cycles. Pricing is project-specific and quote-based, with services delivered either as a direct contractor to industrial end-clients or as a subcontractor to industrial pipe contractors (the more common model). Distribution is single-country (Norway), with a national footprint and particular emphasis on Western Norway, Central Norway, and Northern Norway. Revenue is generated through professional services (project installation), hardware sales (custom insulation pads and prefab components), and recurring maintenance/service contracts on existing installations. Revenue grew from approximately 10 million NOK in 2015 to over 60 million NOK in 2024 under owner-managers Henning and Harald Otnes, with the 2025 merger combining three previously separate entities.

- Brødrene Sunde: Norwegian industrial insulation contractor with regional offices across Western, Central, and Northern Norway. Comparable because it competes for the same industrial and maritime insulation work, serving similar process-industry customers in overlapping Norwegian geographies.
- Apply TB (Apply): Norwegian industrial contractor delivering insulation, rigging, scaffolding, and mechanical services to process industries and shipyards nationwide. Comparable because it competes for the same industrial and maritime insulation scopes in Norway, often as a subcontractor to main contractors.
- Beerenberg: Norwegian industrial services company headquartered in Bergen, providing insulation, scaffolding, and surface treatment to oil & gas, process, and energy clients. Directly comparable because it serves the same Norwegian industrial customer base with similar insulation-and-access services, including modular prefabricated solutions.
Broad incumbents
- Bilfinger: German-headquartered international industrial services provider with Nordic operations spanning insulation, maintenance, and engineering. Comparable because it offers the same industrial insulation capabilities as part of a broader portfolio, often competing with Teknisk Isolering on larger multi-discipline tenders.
- Kaefer: World's largest industrial insulation contractor with strong Nordic operations (including Norway). Comparable because it delivers the same technical insulation services to industrial, marine, and energy clients at global scale, representing the dominant incumbent against which Teknisk Isolering competes for larger scopes.
