Going to start framing soon. Just curious of what type, size, brand or whatever insulation to put in walls? Standard 2x4 build. Heard things like 13 for walls, 19 for ceilings. Does this sound right? Thnx for any replies~

From a sound standpoint the experts here say the cheap fiberglass is just as good as the roxul mineral wool. Your insulation sizes are right (R13 for 2X4 walls and R19 in the joists). I used roxul in my build (mainly) because I found it easier to work with (a little less itchy) but your mileage may vary.

Thank u so much for the reply!

You'll get more responses if you provide more specific information.

Are you insulating for sound containment or thermal? Above or below grade? Any moisture issues or not?

Lowes has a $100 gift card deal right now if you buy $399 worth of insulation.

I'm going to pick up some this weekend - thats a pretty good deal if you have a lowes around. Deal is good until Oct 25th I think.

No moisture issues...below grade, for both sound and warmth purposes.

Thnx 4 letting me know about the Lowes deal!:)

You're probably good with R11 for the walls, but you might want to punch in your exact details into this government website that helps find the recommended R values for different parts of the house by zip code.

Good luck.

A consideration:
If you are insulating below grade with concrete walls - please consider either rigid foam board (the blue or pink stuff).

Or if going with fiberglass fluffy stuff > be sure to use un-faced insulation, and utilize an air gap between insulation and concrete wall surface

R13 is for 2x4 walls. I used R13 for most walls, and a few of my deeper ones I used R19.
R19 for my main ceiling areas in the basement, and 2 layers of R19 in the theater ceiling (since I have lowered the ceiling by about 9 inches.

Just because you can put R19 in a 2x4 cavity doesn't mean you should. As the insulation compresses, it looses its ability to insulate, so no stuffing, it should fit loosely in.

As for sound, it really won't sound proof. Wall isolation, Green Glue, etc is what you need. It will keep the areas from being open cavities that resonate, that is why people put it in their risers, also you do not need to fill the joist cavities 100%, I think I saw Ted White post once that about 2/3 full is good, hence my 2 layers of R19 above the theater, I have about 18 inches of space up there.

Great deal on the R19 insulation.

I just bought 900 feet worth and got the $100 mail in rebate and the 10% off on my total purchase. Saved over $198 bucks after all said and done.

Thanks for the info!
