Using an R19 value for 2 x 4 walls?

If building an additon with a 2 x 4 walls, instead of using an R13 insulation, can I use R19?. Is it more beneficial or will it hurt the actual warmth of the house by squeezing an R19 into an R13 space? Should I bother?Using an R19 value for 2 x 4 walls?

Hello: BBC2

The common thinking is "More Is Better" theory. Works in some cases but not in all cases. More is better when it pertains to engine cubic inches. More cubes equals more horsepower.

Such is not the case with insulation. The "dead air" space is required to provide the insulation properties. Also the ventilation needed.

Stuffing and or packing insulation reduces it's energy saving abilities and reduces the needed ventilation in the material. So more is not always better nor best.

Our resident insulation professionals will likely provide you with more detailed information. Check back on your question several more times.

Why not build the addition with 2x6 walls? that way you can use R-19 insulation.

We have found that it dont pay to try and build with 2"x6" stud wall for more insulation. By the time your done with windows and doors forget it. We go 2"X4"studs and R 13. Then they have many kinds of foam insulation boards out . Some will go to a R 4.5 and better. This is what we put on out side then a house wrap then the siding. Wood or say Drivit. ED

Hi: BBC2

"R13 insulation just doesn't sound like its enough"

"I appreciate all advice, large, small, meaniless or not."

A touch of humor added? Excellent. Glad you included such.

Using insulation will deaden the sound also....
Appreciate advice? Great. Just what the web site is all about.
Plenty of advice. Advice both "Small & Large" Rarely "Meaninless."
Always helpful and provided with good intentions.

Whether R-13 'sounds' right or not, the insulation institute did plenty of research. Testing proved R-13 or R-4.5 is the best for 2x4 wall insulation. Deadens sounds too...

Gas prices are like all other energy and most other consumer prices. Energy prices rise and fall on supply & demand.

Best bet to offset, hedge or recoup some, if not all or more of the heating and cooling billing costs, is to be invested in the energy investment markets.

I'm well "insulated," hear no outside "sounds," appreciate higher natural gas prices & all other higher energy prices.......haha
