R13 wall insulation has a lower thermal resistance compared to R19, making R19 more effective in reducing heat transfer and improving energy efficiency in a building. This difference is particularly important in colder climates where higher insulation values are beneficial for maintaining indoor temperatures. R19 is typically recommended for exterior walls in areas with extreme temperature variations, while R13 might be suitable for interior walls or less extreme conditions. Ultimately, the choice between R13 and R19 depends on local climate, building codes, and energy efficiency goals.
R19 can refer to insulation as well as to a form of explosives. The Renault 19 is a car which is sometimes calls an R19. R19 insulation is usually found as batts insulating the walls of homes.
R 13 for 3.5" wall cavities, R19 for 5.5". R30 for blown in insulation and batts in ceilings.
Higher strength. If you are framing over 12' you will need to double the 2 x 4s or go to a 2 x 6 stud. Sometimes 2 x 6s are used to make the cavity larger to allow pipes to be concealed within the wall. Sometimes they are used to bump the insulation value from a R13 to a R19.
Depends on the MFG, and type. I have seen R19, from 5 inch to 6.5 inch in thickness.
57% gain. A R30 would be the same as a R19 + a R11 batt.
The more the merrier. R19 at least but add a roof ridge vent if you dont have one. That is cheap - 2-3 hundred. My home has no wall or floor insulation. actually 6 to 8 inches of fiberglass blown or batts is neither too much nor too little for any place in the u.s. always better a little too much than too little.
If there is a ceiling below the floor then you can insulate the ceiling and that will insulate the floor using traditional insulation. If you are looking to insulate a basement floor then one of the cheaper forms of insulation is called Thermo-Tech Ultra Light flooring insulation. There are other forms that you can use but this is the least expensive.
You should do a little more research. Heat pumps are not that efficient in colder climates and may not provide adequate heat. Some Geo-Thermal installs may work however. BG in NJ

Sooo different..
Yes, That is a must do.
