Also know, what R value do I need for basement walls?The basement walls need to be insulated to a minimum value of R-10 for continuous insulation (such as foam plastic insulation) or R-13 for framing cavity insulation based on the component requirements of Table N1102. 1 Insulation and fenestration requirements by component.One may also ask, how thick should insulation be? The insulation in your attic should be at least 12″ thick. The thicker the better. It is not uncommon to see 15″ to 20″ of insulation in a well insulated attic. If your attic insulation is only a few inches thick or if you can see the ceiling joists, you’re wasting money on your heating and cooling bills. Similarly one may ask, what type of insulation is best for basement walls? The best way to insulate the interior side of a basement wall is with foam insulation that is adhered to or sprayed directly on the concrete. Any of the following insulation materials are acceptable for this purpose: closed-cell spray polyurethane foam or either XPS, EPS, or polyisocyanurate rigid foam.Is r10 enough for basement?R10 is adequate for a basement, assuming all the walls are below ground. 2 inch thick foam generally gives R10.
