Technical insulation

Technical insulation is about clothing pipes, ducts, and tanks with the right insulation so heat stays where it should, cold does not cause condensation, and fire is slowed. In an AMU course in technical insulation you learn the fundamentals: how to calculate the right thickness, fold sheets so they fit around bends, and perform pipe, duct, and fire insulation properly. You become a technician in a profession where precision and understanding of heat count.

A technician in technical insulation measures, calculates and cuts insulation material and covers it with e.g. PVC foil or sheeting so it both insulates and looks right. You work with pipes and bends, ventilation ducts, tanks and cooler pipes — and you adapt the solution depending on whether the task is heating, cooling or fire. It is a trade where a good layout and a clean final finish is what separates the craftsperson from the amateur.

• 01Basic technical insulation and understanding of heat paths
• 02Calculation of insulation thicknesses so the solution fits the task
• 03Plate unfolding so plates fit snugly around pipes and bends
• 04Pipe and duct insulation plus covering with PVC film
• 05Fire insulation where the insulation must withstand a fire
• 06Cooling insulation, where the issue is avoiding condensation and ice formation

AMU courses in technical insulation are short, practical programs that are open to both newcomers to the trade and experienced workers who want credentials for the basics. If you want to go all the way, the trade is also available as a vocational education with basic course and internship at a company. Talk to a vocational school or AMU center about which path suits your situation.

Course numbers and durations were checked on amukurs.dk on 1 October 2026. Since 21 December 2025 everyone who carries out asbestos work — including removing individual pipe bends with asbestos-containing insulation — must have AMU 22906 (2 days) or, for demolition requiring authorisation, AMU 22907 (4 days).

Technical insulation is a profession with great demand because energy requirements and district heating expansion only make insulation more important. With experience you can specialize in, for example, industry, offshore, or fire insulation, become a crew lead or work manager, and move towards measuring and estimating. It is a craft where skill is directly felt in the energy bill.
