| Completed by | An installer in our network |
|---|---|
| Property | 1960s semi-detached house |
| Approx. age | Built in the 1960s |
| Existing insulation | Around 75mm of old, thin mineral wool, laid between the joists only |
| Loft size | approx. 44 m² |
| Problems found | Insulation well short of the 270mm now recommended, and compressed in places where it had been walked on. The loft itself was dry and sound, with clear airflow at the eaves. |
| Material installed | Knauf mineral wool |
| New insulation depth | 270mm (full recommended depth) |
| Ventilation work | None required — the loft was well ventilated with no sign of moisture or mould. |
| Installation detail | Existing wool left in place between the joists and a second layer laid across them to reach full depth, with the eaves kept clear so air can still pass into the roof space. |
The ceiling line is now insulated to the depth currently recommended for a cold loft, with the roof space left ventilated as found.
