Common duties for an insulation worker include removing old materials and properly disposing of them. Usually, insulation workers put some type of padded lining in buildings or around heating and air conditioning units to improve the overall efficiency of the building. Someone in this position may also have to determine when plastic barriers are needed to protect the insulation from moisture.

As you write your insulation worker job description, think about the skills you want to see in a candidate. Dexterity, the ability to maintain coordination even when working in small spaces, is important for this type of work. You may also want to look for applicants with mechanical and math skills.

As teamwork is necessary for this position, good communication skills are key, as is the ability to follow instructions. Use our professional insulation worker job description template to get a better idea of the details you should include.

Domestic Retrofit

Improving the energy performance of existing housing is seen as a key contributor to meeting the UK’s climate change commitments but refurbishing housing can also improve householders’ thermal comfort, save money and increase security of supply. There has been concern, however, that the standard of design and installation of these energy saving features has often been inadequate. This was a driver behind the Each Home Counts (EHC) Review, which recommends a quality mark and supporting technical codes of practice and standards to cover the design and installation of energy efficiency measures. Key to this is the upskilling and training of those delivering these measures. The Domestic Retrofit Training Course consists of six 20-30-minute modules to raise awareness of key technical refurbishment topics – moisture awareness, airtightness, exposure, external wall insulation, building physics and unintended consequences. The course is consistent with the EHC review recommendations and the proposed technical direction of PAS 2035 Code of practice for the energy retrofit of buildings (and associated standards), which is now being developed. As well as introducing the key technical issues involved, it provides a first step to further training to become accredited under PAS 2035, which will enable practitioners to display the EHC Quality Mark. There is an introductory module but the other modules can be taken in any order as there are cross linkages between them as well as extensive reference to supporting BRE guidance which provides further technical details. The learning outcomes are set out at the start of each module. #### Intended audience The course is designed primarily for surveyors and designer, but is also relevant to domestic refurbishment projects clients, materials providers, installers, site managers and assessors. Users of the modules are invited to provide feedback on the content and the method of delivery so that they can be improved and developed further.
