The r value of insulation indicates its thermal resistance to the flow of heat.

R13 vs r19 sound insulation.

Square feet of house or area to be insulated current and desired r value for insulation and type and cost of your energy. Adding standard fiberglass insulation improves the rating to stc 39. Going from r 11 to r 13 just involves using a different insulation but going from r 13 to r 15 the whole wall r value for 2x6 walls requires going from 2x4 to 2x6 walls and thus more insulation more lumber and doors and windows with wider jambs. What you re trying to block are airborne noises.

Higher numbers indicate insulation that is more effective. Thermal values range from a low of r 4 to a high of r 45. However the r value of insulation also depends on proper installation to avoid compressing it. Adding sound rated insulation can improve that to stc 45.
