Working Life
Cavity wall insulators inject insulation materials between the walls of houses or other buildings to retain heat. They drill holes into the outside walls of a building and use a pump or a vacuum to suck insulation material from bags. This is injected into the walls of the building. Insulators may also be required to complete more traditional insulating work using materials such as kingspan etc. They need also to keep up to date with new advances in insulation.
Insulation materials include mineral fibre, expanded polystyrene beads, granules or foam. A cavity wall insulator needs to have a basic knowledge of buildings and how they are made so they can use the most suitable insulation material.
Most insulators work in pairs so that one can drill holes while the other fills the cavities. When the job is done, the cavity wall insulator cleans up the area and fills the holes in the brick with a matching mortar. They may be required to insulate existing structures or new buildings.
Cavity wall insulators wear protective clothing such as overalls, a face mask, goggles and ear defenders.
Most commonly reported Work Tasks
- Measure and cut insulation for covering surfaces, using tape measures, handsaws, power saws, knives, or scissors.
- Fit, wrap, staple, or glue insulating materials to structures or surfaces, using hand tools or wires.
- Cover and line structures with blown or rolled forms of materials to insulate against cold, heat, or moisture, using saws, knives, rasps, trowels, blowers, or other tools and implements.
- Distribute insulating materials evenly into small spaces within floors, ceilings, or walls, using blowers and hose attachments, or cement mortars.
- Move controls, buttons, or levers to start blowers and regulate flow of materials through nossles.
- Fill blower hoppers with insulating materials.
- Cover, seal, or finish insulated surfaces or access holes with plastic covers, canvas strips, sealants, tape, cement or asphalt mastic.
- Read blueprints, and select appropriate insulation, based on space characteristics and the heat retaining or excluding characteristics of the material.
- Remove old insulation, such as asbestos, following safety procedures.
- Prepare surfaces for insulation application by brushing or spreading on adhesives, cement, or asphalt, or by attaching metal pins to surfaces.
Qualities - Insulation Workers
As a cavity wall insulator you need to be physically fit and strong as you will need to stand for long periods, work from ladders and scaffolding, and lift heavy equipment. It is useful to have a basic knowledge of how buildings are constructed. You need to have a clean and tidy approach to work. You will need to be able to work alongside other trades people
Although you will wear protective clothing and a face mask, the job may not be suitable for you if you suffer from allergies to dust or fibres. The ability to drive is useful.
Interests - Insulation Workers
This occupation is typically suited for people with the following Career Interests:
Realist
Realists are usually interested in 'things' - such as buildings, mechanics, equipment, tools, electronics etc. Their primary focus is dealing with these - as in building, fixing, operating or designing them. Involvement in these areas leads to high manual skills, or a fine aptitude for practical design - as found in the various forms of engineering.
Realists like to find practical solutions to problems using tools, technology and skilled work. Realists usually prefer to be active in their work environment, often do most of their work alone, and enjoy taking decisive action with a minimum amount of discussion and paperwork.

Labour Market Updates - Insulation Workers
Note: The following information relates to occupations that include: Bricklayers and masons, Plasterers.
This information has been derived from the Solas National Skills Bulletin (2025).
Annual average employment growth over the five-year period was negative for bricklayers/plasterers, although employment has grown strongly since 2023 (an additional 2,500 persons), with numbers almost returning to 2019 levels. Just 55 new employment permits were issued (three fifths for bricklayers, the remainder for plasterers), down from 191 in 2022 and 84 in 2023.
A small number of difficult-to-fill vacancy mentions were identified for blocklayers in the Recruitment Agency Survey. Vacancy posts in the DSP Jobs Ireland data were primarily for plasterers and brick/block layers followed by stone masons. In 2024, the number of new apprentice registrations for brick and stone laying was 78 (an 18% increase compared to 2023, although just below 2019 registration levels), with 28 awards in 2023. Since 2022, the number of new plastering apprentice registrations remained at around 30 annually, compared to 36 in 2019, with just 3 awards in 2023 (down from 19 in 2022).
Increased uptake of MMC for housebuilding is expected to lead to a reduction in the demand for plasterers and bricklayers but in the short-term, any acceleration of house building or residential repair/retrofitting activity may lead to issues with sourcing supply for these roles.
