Should I frame with 2×4 or 2×6?
There is a school of thought that the larger 2×6 studs will conduct less heat outside than 2×4 members, both because there are fewer of them and because they are thicker, front to back.
This is logical, and makes sense, but will not be nearly as important as the insulation factor in the walls and windows..
How much weight can a 2×6 wall support?
FWIW: “A single SPF#2, 9′ x 2×4 that’s restrained laterally by sheathing or blocking can support 1820 lbs and a similar 2×6 can support 7061 lbs without buckling (almost 4 x as much). A double 2×4 can support 3639 lbs, or about half that of a single 2×6.
How far apart are 2×6 studs?
Wood-framed houses have traditionally been built with 2×4 studs spaced 16-inches on-center. Research has shown exterior framed walls can be adequately supported by 2×6 studs spaced 24-inches on-center.

Can I use 2×4 insulation in a 2×6 wall?
Fiberglass and rock wool batts – 2×4 walls can hold R-13 or R-15 batts; 2×6 walls can have R-19 or R-21 products. … Use R-19 or R-21 kraft-faced fiberglass insulation for two-by-six (2×6) walls. This combination ensures that the insulation is neither too loose nor too tightly packed within the walls.
Is R 13 wall insulation good?
Typical recommendations for exterior walls are R-13 to R-23, while R-30, R-38 and R-49 are common for ceilings and attic spaces. See the Department of Energy’s (DOE) ranges for recommended levels of insulation below.
What is the most cost effective insulation?
Highest R-Value Per Dollar, Most Cost-Effective Insulation…EPS is good for your overhead. Some EPS products can help roofing contractors save up to 57% on labor costs. … Continuous value in continuous insulation. EPS is one of the most versatile rigid insulations because it can be used anywhere in the building envelope – roof, walls or below-grade. … Go green while saving green.
What is the most efficient insulation?
Aerogel is more expensive, but definitely the best type of insulation. Fiberglass is cheap, but requires careful handling. Mineral wool is effective, but not fire resistant. Cellulose is fire resistant, eco-friendly, and effective, but hard to apply.
What is the best insulation for 2×6 walls?
The installed insulation R-value for 2×6 fiberglass batt ranges between R-19 and R-21. When blown or sprayed cellulose insulation is used, the R-value is typically R-20 for 2×6 walls.
What type of insulation do you use in walls?
When it comes to the best insulation for walls, the insulation material can also impact the R-values needed for good energy efficiency. Fiberglass: Fiberglass is the most common insulation material. It’s made from fine glass fibers and is most often used in batts, rolls and loose-fill insulation.
What is the highest R value for a 2×4 wall?
Fiberglass vats are the standard insulator for 2-inch by 4-inch wall framing, and are rated R-11 through R-15. In order to achieve the higher insulation R-value of R-21 a different type of insulation will be required.
Are 2×6 walls worth it?
The cost to build with 2×6 is also high and at a minimum adds $2,149.90 to the cost of the build, even more if you upgrade your insulation. The energy savings from building with 2×6 are minimal and don’t outweigh the costs, saving about $. 02 per sq/ft living space or $41 per year.
