I got the free loft insulation 2 years ago, the foot deep stuff on the attic floor, however I have been in recent communication with the supplier as I also have insulation on the underside of the roof, and as the idea is not to keep heat in the roof space they have agreed to take out the insulation attached to the underside of the roof to ensure no dampness occurs at a later stage and to increase ventilation. They admit that they should not have put the floor insulation down when there was already roof insulation in place.
Is this the correct thing to do or anything I should be aware of.
