Should you insulate your interior walls?
Many homeowners choose to insulate their interior walls to create a sound barrier between rooms. Though no insulation can completely soundproof a room, interior insulation can significantly reduce noise transfer. For light sleepers, sound dampening is especially helpful in the walls of a bedroom.

What R-value should I insulate my walls?
R-13 to R-23Depending on where you live and the part of your home you're insulating (walls, crawlspace, attic, etc.), you'll need a different R-Value. 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.

Can you over insulate a house?
It is possible to over-insulate your house so much that it can't breathe. The whole point of home insulation is to tightly seal your home's interior. But if it becomes too tightly sealed with too many layers of insulation, moisture can get trapped inside those layers. That's when mold starts to grow.

Does doubling insulation Double R-value?
Doubling the thickness of insulation will double the insulation's R-value, cutting heat loss in half. Each time the insulation layer is doubled in thickness, this rule applies.

Can I use R 13 in a 2x6 wall?
They are available in widths suited to standard spacings of wall studs and attic or floor joists: 2x4 walls can hold R-13 or R-15 batts; 2x6 walls can have R-19 or R-21 products. Loose-fill insulation—usually made of fiberglass, rock wool, or cellulose—comes in shreds, granules, or nodules.
Do I need faced or unfaced insulation?
Unfaced insulation is non-combustible. However, it's common for a layer of faced insulation to be used in the exterior walls and attic ceilings to prevent water from entering the home, while unfaced insulation can be added to improve the heat retention ability and reduce the risk of fire.
Are 2x6 walls worth it?
2x6s Will Result in a Better Insulated Home – Usually Not surprisingly, a 2x6 frame construction allows for more space between your interior and exterior walls. This extra space alone typically doesn't result in better insulation, but it does offer more room for added insulation.
Which way does insulation face in walls?
The first layer should have the facing against the drywall to act as a vapor barrier. (The general rule for insulation is that the facing always goes toward the conditioned space.) The second layer of insulation should be unfaced so that moisture doesn't collect between the layers.
Does insulation need to be stapled?
Stapling the insulation batts is not necessary to secure them in most cases. However, it is the easiest way to keep them in place, as most products are already equipped with tabs or strips for stapling into the framing joists.

How do you hold insulation in walls?
Snug-fitting insulation will stay put without fastening, but faced insulation is available with stapling flanges—extra paper facing along each side edge that allows you to staple it to the side of the wall stud. Open-faced insulation can't be stapled, so it needs to fit snugly for friction to hold it in place.
What happens if you seal a cavity with R-19?
If the cavity was completely filled with R-19 there would still be air between the sheathing and insulation. Air Sealing - only retards air movement. Hermetically sealing prevents any air movement but that isn't going to happen for a nominal fee in residential construction.
What is R-13 compressed?
R-13 is just R-19 compressed, same amount of fibers, smaller air pockets. You don't want an air space on either side of batts, unless the sheathing was air-sealed.
What is the best R value for a 2x6 wall?
The best R-value is the one with 2 inches of exterior insulation. The 2×6 wall is roughly equivalent to a 2×4 wall with a half-inch of exterior insulation.
Can you frame 2x6 walls?
But they can frame 2×6 walls. There’s a learning curve with exterior insulation. If you have a crew that can deal with 2 inches of continuous exterior insulation, though, you can cut the heat transfer through your walls in half and still end up with walls the same thickness as 2×6 walls.
Is it important to keep exterior insulation dry?
The colder your winters are, though, the more important it is to keep your exterior sheathing dry. Exterior insulation over the sheathing is great for that. One of the weaknesses of double-stud walls is that the sheathing stays colder and thus wetter, possibly even wet enough in cold climates to cause damage.
Is 2x6 insulation good for winter?
Whether you go with a 2×6 wall or a 2×4 wall with exterior insulation, that extra insulation means that the inside surfaces of your exterior walls won’t be as cold in winter or as warm in summer. Now, you may think that doesn’t matter a whole lot as long as your heating system or air conditioner is up to the task, but you’d be wrong.
Does slab edge insulation reduce heating load?
Slab-edge insulation would reduce their heating load by 25%. (And believe it or not, their heating load is higher than their cooling load.) Whether or not you go for an improved wall assembly in a warm climate depends on your particular priorities. It’s not the slam dunk it is in a cold climate, but there are benefits.
How deep is a 2x4 wall?
Since modern two-by-fours are not 4 inches, the true depth of the wall cavity is 3 1/2 inches.
What happens if you cram insulation in a wall?
If you cram too much insulation into a wall that is too thin, you reduce the insulation's air pockets and thus reduce its ability to provide thermal resistance. A thick down-filled jacket or sleeping bag works the same way. When the feathers fluff up and create air pockets, thermal resistance is at its greatest.
Can you add insulation to a cold house?
When you add too little insulation, you will have a colder house. Ironically, adding too much insulation—packing in more than is needed—can also result in a colder house than is necessary. Tiny air pockets created within the insulation are what help keep a home toasty and warm, not the actual strands of fiberglass or paper facing.
Does spray foam sag?
Spray foam cannot lose its shape, except under extreme pressure. It will not sag or settle over time. Long used in commercial buildings, spray foam insulation is now finding its way into more residential spaces. Spray foam insulation is not a do-it-yourself project.
Can you force away air pockets in insulation?
Millions of tiny air pockets are basically pre-installed in the insulation and they cannot be forced away. Spray foam insulation seals all areas of the cavity: walls, floors, ceiling, along with the structural members, holes, cracks, and seams.
Does cellulose insulation fit in the attic?
Cellulose insulation does not fit the wall cavities as adequately as fiberglass insulation does. Short of rebuilding your walls to thicker dimensions—a cumbersome, expensive project—look at alternative ways of preventing your costly artificial heat from escaping: Add thick insulation batts to the attic.
Can you spray foam insulation yourself?
Long used in commercial buildings, spray foam insulation is now finding its way into more residential spaces. Spray foam insulation is not a do-it-yourself project. Generally, you'll need to hire professionals to apply spray foam.
