Review Of 2X4 Or 2X6 Exterior Walls New Ideas, The house has a third car space added, with 2x4 unfinished walls standing over a concrete block foundation with 2x6 plate. Spray applied, it effectively seals the structure forming an air infiltration barrier. The question becomes all more critical because of the permanent nature of wall assemblies and wall insulation :

I've Also Had 2X4, And 2X6 Is Far Superior, At Least In This Climate, Both For Energy Saving And Quietness.


However, more emphasis imho should be paid to the ceiling. Modern conventional home building normally makes use of 2×4 lumber (top line above, second from left) in constructing exterior walls. 2x4 exterior walls are actually acceptable exterior framing, it's just that you need r20, which you can't get with just fiberglass insulation in a 2x4 cavity.

More Importantly, You Have Less Thermal Bridging, Which Is Heat/Cold Being Transferred Through The Framing Elements.


So although it's more cost, it's not that much more. The difference then, between the two is too small to justify the added cost of the 2x6 and the necessary extended jambs. Also know, is a 2x4 stronger than a 2x6?

Typically 2X6S Are Cheaper Than 2X4S On A Per Thousand Basis.


The total difference in cost to build your house with 2x6 exterior construction vs 2x4 is $2,149.90. Brickeyee 12 years ago being the walls aren't a major heat gain area (glass is), i recommend you concentrate more on radiant barrier, ridge vent, soffit vents, and a hefty layer of attic insulation. I've seem infrared images of houses, and you can see every stud due to this.

Once The Insulation Is In The Wall And Sealed Up With Drywall, It Is Not Easy To Change Out.


Two exterior walls constructed with 2×6 and 2×4 respectively, without any added foam or other insulation around the outside, show that 2×6 is superior to 2×4 exterior walls. So if you see such framing and are wondering how it passed, they probably also used blue insulation on the outside, or something else to achieve r20. This is logical, and makes sense, but will not be nearly as important as the insulation factor in the walls and windows.

2X6 Walls Are Bigger Than 2X4 Walls.


They're harder to lift and the headers on exterior walls require more work. Decide if you want the door flush on the inside or outside. Install the door than take a 2x4 or 2x6 and frame up the part that exteds.

Click to see full answer. Currently in climate zone 5 we have r49 ceiling requirements, and r20 at the walls (there are exceptions of course). It isolates the exterior climate from the interior climate, greatly reduceing the loss of heating/cooling btu's through the wall via convection/conduction.

And it's usually a bit cheaper to frame. I will use the table saw to rip 2x6 studs in 2 strips, which will then be used to fur the 2x4. I am in the process of finishing it as a workshop and i want to make the wall 6 for better insulation. So, the extra cost in plates is $594.88 add all of this together and, so far, going from 2×4 to 2×6 walls costs an extra $2,334.88 in lumber. 2x6 walls are bigger than 2x4 walls. 2x6 Construction or 2x4 Construction on New Home Builds
