We live in a 1930's 3 bedroom house. We installed loft insulation last year and since then we have expirenced lot of condensation in the loft. Even the rafters have mould.
We have the water tank in the loft. We put four vents but the problem this year is very bad.
I have read that people has reduced the amount of insulation ijn the loft to control the condensation. Any ideas please!!!
Thanks for your time
