What insulation should I use in my basement?

Choosing the Best Insulation for Basement Walls and Ceiling



If you are looking for a less expensive option that you can install yourself, then foam board or fiberglass will be the better options. If you want that air seal in your basement to make the space more comfortable, then spray foam is the way to go.

What insulation is best for ceilings?





Spray foam insulation is the most effective type, with a maximum R-value of 6.5 per inch.

What R value should I use in my basement?

The Model Energy Code recommends R-11 insulating values for basement walls in most of the country and R-15 for the northernmost states.

How thick should basement insulation be?

The recommended R level is 25. To achieve the recommended R-value level, you’ll need 3.84 inches of insulation (25/6.5=3.84). Once you have determined what the appropriate R-value is for your home, you will need to decide whether you want to use open-cell or closed-cell foam insulation.

What is R30 insulation used for?

A wall is R-19, a roof is R-30 — what does this mean? Essentially R-value is a measure of thermal resistance, or the ability to prevent the transfer of heat. The larger the number, the harder that insulation is working at preventing heat conduction. The less heat loss, the lower your energy bills.

How thick is R30 insulation?





8¼ ” thick, R-30C EcoTouch® Thermal Batt insulation prevents moisture damage and helps assure long roof life by providing 1″ of ventilation air space between the insulation and roof deck. Easy Installation R-30C EcoTouch® Thermal Batt insulation is easy to handle and install.

How do I install R30 insulation in my ceiling?

Quote from the video:
Quote from Youtube video: Once the rafter mates are in place you can begin installing insulation simply push the bat straight up through the ceiling joists. Then pull it back down. So the bat fits evenly in the space.

Is R 13 insulation Good for basements?

TBF closed cell foam insulation and concrete board basement wall products offer industry-leading R-13 insulation value that will reflect back 99.987% of heat back and lead to the optimal insulating of a basement area.

Should you put insulation in basement walls?

Walls. Basement walls should be insulated with non-water sensitive insulation that prevents interior air from contacting cold basement surfaces—the concrete structural elements and the rim joist framing.

Is insulating basement worth it?



Insulating your basement may seem like a project best suited for another day, but truthfully, insulating your basement walls can help improve comfort and reduce energy and maintenance costs to HVAC systems. It also allows for extra living space within a home, which can be invaluable.

Is R30 insulation good for walls?

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.

How much space do I need for R30 insulation?

Give yourself another inch and a half, put the R30 in there. All you need is about a half inch to three quarters of an inch air gap in there. You don’t need anything big, and make sure it’s vented.

Which is better R19 or R30 insulation?



The bigger the R value, the better the insulation is at slowing down the heat transfer. So R19 is better insulation than R13, and R30 is better than R19. The larger the R value, the better the insulation value.

Is R30 insulation good for sound?

R30. R30 is another suitable soundproofing material for ceilings and attic spaces. It’s usually about 10.25 inches (26.04 cm) thick, though you can find various thicknesses depending on the type of material you use for insulation. R30 helps with sound absorption to eliminate unwanted noise.

What insulation is best for soundproofing?

When it comes to soundproofing, mineral wool insulation is the best. It is denser and stiffer than fiberglass and features higher R-values. It also has less of a tendency to become compressed over time, which would lessen both its thermal ability and its sound-absorbing qualities.

What kind of insulation should I use for interior walls?

Because they have a high R-value and can be used nearly anywhere in your home, foam board insulation is one of the most common types of insulation. Best for floors, foundation and basement walls, interior and exterior wall sheathing and low-sloped ceilings.

What is a good R-value for interior walls?



Depending on the insulation properties of the existing wall, in general the R-values of the renovated walls can be between R-19 and R-22 (0.25 to 0.30 W / m² K) – without additional risk to the structure.

Should you insulate basement ceiling?

Yes. Faced insulation is actually recommended on basement ceilings and ceilings in general. The covering or “face” of the insulation prevents it from falling out and trickling down into the basement air. This is especially advantageous if the insulation is made of fiberglass, which can harmful if it’s ingested.
