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.
Thereof What do you put under floor? Underlayment, or âpaddingâ as it’s often called, is the spongy, closed-cell plastic foam sheet that comes in rolls. It is rolled out between the actual laminate flooring planks and the subfloor.
