Hello,

We recently had to pull up the timber floorboards in our back room to do some serious pier work. The room itself gets pretty cold - it has two external walls, two large windows and French doors. Before the floor boards go back down, we want to insulate the floor (the walls and ceiling will be insulated as we go too). I was told that using yellow tongue underneath the timber boards is the quickest and easiest way to go. Is this true? And does the yellow tongue insulate well?

Cheers,
Leah
