I have an old, cold house and the loft has a couple of rolls of what looks to be cheap insulation. I'm looking to put more down but I'm wondering if there's a point whereby adding extra doesn't actually help? I don't mind spending a good few hundred on a lot of rolls if each one will help, but would obviously rather not if there's very little difference between say 2 or 3 layers. Any thoughts/ info would be greatly appreciated!
Okay so can I get some more back story her? Heating system? R value of what’s up there now? Kind of build it is? Insulation in walls? I am an insulator and plumber. I work on Old houses and mobile homes only.
Have you considered or looked into blowing cellulose insulation? It is fairly easy and inexpensive to add over existing insulation.
