Had 8" insulation istalled in attic on top of 4" old insulation 2 years ago
Bad condensation over last 2 winters in rear bedroom. Got installer back and felt ventilators fittedin roof ..No improvement..The attic itself was dry!...Solution ( I hope !). We are having the 8" insulation removed,after hearing and reading horrendous stories in the media over the past 6 years and also on the advice of the installer who is getting a wave of complaints over this past winter. comments please
