Hi,
I've recently moved into a 30 year old house which current has a warm loft. The insulation is up against the roof with plasterboard keeping it put. I understand that there needs to be a gap between the insulation and the roof felt and I have no reason to suspect that this wasn't done. There is no insulation in the loft floor. There are also no vents in the eaves which I presume is correct when having a warm loft.
My question is how much heat is lost from the bedrooms into the warm loft? And is it very ineffecient to have a warm loft if I only store things up there? We want to keep storing items in the loft but at the same time keep the heat in the bedrooms. Should I insulate in the loft floor as well or will this cause me problems with condensation, etc. What is recommended for this situation? If I insulate the loft floor do I need to remove the insulation in the roof and add some vents in the eaves, therefore converting it into a cold loft? Could I just add some 100mm/170mm thickness insulation in the loft floor to allow some heat to stay in the room and allow some heat into the loft?
Many thanks in advance, Paul.
