We live in an old house that is very badly insulated. The loss of heat comes mainly from the roof. What type of insulation could we install knowing that the roof height is limited and that there are many transverse beams?
If the lack of space does not allow you a large thickness, it will turn to a blown insulation, mineral or vegetable?
Another solution well suited to novice DIYers as shown in our sheet is the insulation floor of the attic (loose wool) from Isover.
