Can I use R-13 insulation for a basement?

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.

What is a good R-value for basement insulation?

Understand “R values” — the measurement of insulation’s effectiveness or thermal resistance. The Model Energy Code recommends R-11 insulating values for basement walls in most of the country and R-15 for the northernmost states.

Where do you use R-13 insulation?

R13 batt insulation is typically used to attenuate sound in interior wall cavities. It is akin to a large blanket, designed specifically to fill a wall, floor, or ceiling cavity.

What insulation should I use in my basement?

There are several types of basement wall insulation, including sprayed foam, bubble foil, foam board and fiberglass. Sprayed foam insulation is a viable choice for a homeowner who is looking for a do-it-yourself option for a finished basement. The foam is applied in exactly the manner as it sounds — with spray cans.

Do you need to insulate interior 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. This is why it is important that interior insulation assemblies be constructed as airtight as possible.

What insulation should I use for basement walls?

Can you double up R 13 insulation?

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. It’s much more expensive to add that much insulation to exterior walls.

Is R 13 or R-15 better?

Is R15 Better than R13? Answer: There isn’t much difference between R13 and R15. However, higher R values offer higher performance. Therefore, in the case of efficiency, R15 is better than R13.

How thick is R 15 batt?

3½ ” thick
3½ ” thick R-15 EcoTouch® insulation delivers 36% more R-value than standard R-11 fiber glass insulation.

Do I need a vapor barrier on my basement walls?

Building codes usually require a vapor barrier (4 mil plastic sheeting) on exterior basement walls if the framing is attached to masonry or concrete surfaces, or if the wood framing butts up against the outer basement walls.
