Sheep’s wool: forgiving with damp, good for older homes
Wool can take up some moisture and give it back without losing much warmth, which makes it a good match for older lofts that run a little damp.
Illustration: sheep’s wool laid between the joists
| What it is | Treated sheep’s wool, in rolls |
|---|---|
| Where it goes | On the loft floor, between and across the joists |
| Good for | Older homes; lofts prone to some moisture |
| Worth knowing | Costs more; treated against moths |
| Fix | Laid on a clean floor once the cause of damp is fixed |
Why it suits older lofts
Wool can absorb some moisture from the air and release it later. In lofts where conditions vary, that helps. It doesn’t replace fixing the damp, though.
Where it goes
Between and across the joists on the loft floor, eaves kept clear. Never between the rafters.
Worth knowing
It costs more than mineral wool and is treated to keep moths off. Your quote can compare it.
Common questions
Will wool fix my damp loft?
No. The cause of the damp needs fixing. Wool is just more forgiving afterwards.
Do moths eat it?
It’s treated to resist them.
