Can anyone help me?
We have a house built approx 40 years ago with solid chip board floor. Carpet in all rooms and good underlay.
Is it worth installing insulation/ I thinkthe thick chip board is pretty good and there will be no significant or noticable difference.
Does anyone know? It is going to cost just over $3000 with subsidy off. Novatherm has been recommended.
I live in middle of South Island. We get good frosts
