Cavity wall insulators install insulation into the space between the walls of new and existing buildings. They load the materials required into a van and travel to the site. On arrival, they check that the cavity is suitable for filling and make a note of the decision, together with any comments on the state or age of the building.
They normally work alongside another tradesperson and begins by drilling holes in the walls of the building. The holes are drilled to a set pattern, using handheld electric or pneumatic drills. They work from ladders or, on tall buildings, from platforms or cradles.
They calculate the amount of wool, foam or bead required for insulation. They then pump the insulating material into the cavity between the walls.
The average working week is around 45 hours or more - this may include weekends. Much of the work takes place outdoors, in all weathers. Conditions can be dirty, cold, wet and dusty.
Salaries range from around £15,000 to £25,000.
