R11’s unfaced design makes it ideal for thermal protection. The wall insulation for 2×4 framing is 15 pieces per bag, and the installation is usually 15×40 long and 24×86 wide. You can buy this insulation material in pre-cut sizes that allow them to fit a wide range of standard wall cavities. R11 works best for controlling sound from the outside. You can get these from places with your ideal window frames, door frame switches, and outlets. Other than batts, you’ll want airtight exterior walls. The good thing about the R13 Batt is you can easily twist it to get a perfect fit. You can safely use an insulation knife or scissors to remove the insulation. A regular stapler can secure the wool insulation in place. When installing an R13 insulator, ensure it reaches all sides of the cavity you’re insulating. To properly install your R13 Batt, you’ll need the following: It has an R-value of up to 3.8 per inch.It’s easy to prepare before installation.The insulator’s Noise Reduction Coefficient (NRC) absorbs 90% sound.Its installation is easy, requiring only staples to insulate your wall.Whether you’re building a new house or remodeling the existing one, there are a few reasons you should choose R13 batt insulation. The R13’s design works best with well-sized modern homes. It can fill a floor, wall, or ceiling cavity. Its spray cuts down indoor and outdoor sounds and does a decent job of reducing outside noise. R15 has additional variants depending on its ability to reduce noise. R15 works best with 2×4 walls and is also a decent thermal regulator. Faced insulators have a barrier on their head, while unfaced ones are best to use on top of existing insulators. You can buy this soundproofing insulation material faced or unfaced. The insulation material facilitates soundproofing and is an efficient thermal regulator. R21 comes in rolls, and you can use it to insulate your 2×6 walls. R21Īlthough R21’s density is higher compared to R19’s, it’s somehow narrower than the latter. However, you cannot use it for a 2×4 wall due to its thickness. What’s more, its design fits well in cavities sized 2×10. R30 can cut conductive heat loss from your home by 97%, saving you energy bills. R30 helps with sound absorption to eliminate unwanted noise. 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 is another suitable soundproofing material for ceilings and attic spaces. What more could you ask for from a soundproofing material? R30 Also, it’s easy to install and cost-effective. This insulator is energy-efficient because of its higher R-value, and its soundproofing abilities are top-notch. It’s about 12.75 inches (32.39 cm) thick, suitable for insulation and soundproofing. It’s strong enough to retain heat and minimize damage to your roof. Like R49, R38 is a common insulator for attics and ceilings. To insulate using R49, you need seven to eight inches (17.78 to 20.32 cm) of closed-cell foam depending on the material you’re using, and 12 to 13 inches (30.48 to 33.02 cm) open-cell. It’s easy to install, even for beginners.It’s dimensionally stable and will not slump or decay when installed.It’s non-corrosive, meaning it won’t harm copper, aluminum, and steel.A utility knife can trim and fabricate the material into your desired shape.The insulation material is 16.25 inches (41.28 cm) thick, improving its ability to insulate your home.įurthermore, R49 is a flexible fiberglass material that absorbs noise and regulates the moisture in places like joists and studs. You can usually find it in attic spaces and ceilings. R49 is the best insulator for thermal regulation and soundproofing. Many R-values are available, and I’ll explain the most common ones below. Before you pick the best R-value for soundproofing a specific area for a particular purpose, check their respective pros and cons first. I’ll also discuss what to consider when selecting R-values for soundproofing and answer any other questions you may have about soundproofing and R-values.Īlso read: Best Insulation Materials for Soundproofing And Acoustics The Best R-Values for Soundproofing This article will cover the R-values that work best for soundproofing. Each of these works best for different purposes. Other R-values you can consider for soundproofing include R38, R30, R21, R15, and R13. The best R-value for soundproofing is R49, which works best for places like ceilings and attics. Ultimately, the best R-value for soundproofing depends on your needs. However, there is some correlation between a material’s R-value and its ability to mitigate unwanted noise. R-value seems like it matters more for insulation than soundproofing.
