What is the best floor insulation?
Achieving a U value of 0.25 would be a good target. That would need 90mm of rigid foam or 150mm mineral wool. A semi-rigid material is generally best as it can be cut very slightly oversized and squeezed in between the floor joists, thereby ensuring no draught-causing gaps.
Should you insulate between floor joists?
In unfinished attic spaces, insulate between and over the floor joists to seal off living spaces below. If the air distribution is in the attic space, then consider insulating the rafters to move the distribution into the conditioned space.
What insulation goes under floorboards?
Insulating timber floors – part 1 Answer: Ideally a fibrous insulation such as mineral wool or sheep’s wool performs best between timber because it will take up thermal movement and cut down air movement around the insulation. ‘Thermal bypass’ affects performance, so cutting out draughts is preferable.
