Thermal insulation contractors, often known as insulation engineers, specialise in applying insulation materials to pipes, vessels, boilers and ductwork in a variety of settings such as factories, office buildings, petrochemical plants, power stations and ships. The insulation can be used to trap and conserve heat, or in the case of refrigeration and air-conditioning installations, keep heat out.

Thermal insulation engineers consult blueprints and diagrams to work out where insulation is required and they select the appropriate materials for the job. Surfaces are prepared and cleaned, materials measured and cut to size, then fitted using clips, adhesives or cement. Engineers also use machine blowers to fill cavity spaces between walls, floors and ceilings.

Once the insulation has been installed, the work area is sealed with metal or plastic cladding to protect it from damage or the environment.

Some projects involve stripping out old materials before being re-insulated. This often means the removal of hazardous substances such as asbestos, so observance of health and safety regulations is extremely important.

Hours and Environment

Thermal insulation engineers usually work 40 hours a week, Monday to Friday, although overtime may be required to complete a project.

Working conditions can be cramped where spaces are confined or difficult to access; they can also be hot, dirty and dusty. Work is also carried out at heights. Engineers normally wear protective clothing, especially when dealing with asbestos removal.

Extensive travel, with extended periods away from home, is usually required to work on different sites and projects. A driving licence is helpful.

Skills and Interests

To be a thermal insulation engineer, you should:

• have good practical skills for cutting, shaping and fitting materials
• have good numeracy skills for taking measurements and calculating quantities
• be in good health
• be able to work in confined spaces and at heights
• be able to work as part of a team
• follow safe working practices
• be willing to travel.

Entry

Young people aged between 16 and 23 can apply for an apprenticeship training scheme through the Insulation & Environmental Training Agency (IETA). You need a minimum of four GCSEs/S grades or equivalent, in subjects such as maths, English, science, technology or engineering. For more details, contact IETA in Further Information.

Companies may accept applications from people with a qualification and/or experience in engineering, construction or heating and ventilation. Contact local colleges and companies for possible opportunities.

Training

As an apprentice, you will study for NVQ/SVQ Thermal Insulation Level 2.

The qualification includes:

• erecting and dismantling access platforms
• applying insulation materials
• fabricating and fitting protective cladding
• working safely.

Training involves on-site training and assessment through an employer. It is combined with a minimum of 20 weeks at one of the IETA’s approved training centres based in Darlington and Glasgow.

Opportunities

Opportunities for thermal insulation engineers are increasing, as issues around energy conservation and environmental impact of buildings become more important.

There are opportunities for employment throughout the UK and overseas. Promotion prospects include technical, supervisory and managerial roles. Movement to related areas is possible, such as heating and ventilation engineering or air-conditioning and refrigeration. See the profiles for Heating and Ventilation Fitter, and Refrigeration / Air Conditioning Technician.

Annual Income

Figures are intended as a guideline only.

Thermal insulation engineers usually start between £11,500 and £14,000.
Experienced engineers can earn between £15,000 and £20,000.
Senior thermal insulation engineers earn up to £22,000.

It is common to work on a long- or short-term contract basis with the possibility of extra payments for early completion. Further allowances may be payable for extended periods away from home.
