Sheeps Wool and Airtightness

4-bed Victorian brick house in Shrewsbury

Brick and stone houses built before 1930 are usually single skinned properties and therefore lose a lot of heat through the walls.

The customers had already insulated parts of their house and felt the benefit, so wanted the work continued using the natural and breathable material sheep’s wool when they could afford it.


The Process

1. Insulation

Timbers were fitted vertically against the wall and wool placed between them, held in place with central fixings.

2. Making everything airtight

To improve on draughts, an airtight membrane was fitted over the timbers before fitting the plasterboard. The membrane is taped to the floor, the ceiling and against the window reveals.

3. Finish

The plasterer skimmed the plasterboard to give the room a smooth finish.

The Outcome

The home now benefits from better airtightness and retains the heat much more.
