Is R19 Insulation More Effective than R13?

The higher the R-value, the better insulation, right? No way. Attics commonly use R19 insulation, but it’s not always the best option. For example, in some situations, Wall insulation R13 is designed to be more effective than R19.

The reason is heat flow. Heat moves from hot to cold, following the path of least resistance.

R19 insulation is designed to resist heat flow downward in an attic. But heat moves horizontally in a wall. So R13 insulation is better for walls because it resists horizontal heat flow better.

All in all, R19 insulation soundproofs like R13 insulation, But don’t just pick the higher number if you choose between R19 and R13 insulation. Before choosing, consider your specific needs.

What Is R-Value Best for Soundproofing?

The R-value is one of the key metrics used to assess soundproofing materials. Because these materials are dense and packed, R-13 and R-19 insulation are typically considered the best soundproofing R-values.

Generally, higher R-value materials better block unwanted sound waves from entering or exiting a space.

So, if you want to improve your home or office’s soundproofing, choose an R-value that is high enough to block out external noise effectively.

But what does R-value mean? The R-value measures a material’s resistance to heat transfer via radiation, convection, and conduction. Choosing high R-value materials like R-13 or R-19 insulation are the best insulations for soundproofing. With proper installation and maintenance, you can enjoy peaceful living all year!

Frequently Asked Questions

Can A Room Be Completely Soundproof?

Not Actually! No matter how thick the walls or ceiling are, the sound will leak. It’s a paradox since sound is defined as the wavelike vibration of air molecules. However, soundproofing has improved dramatically due to new materials and construction methods.

Does Foam Insulation Reduce Noise?

Yes, foam insulation effectively reduces high- and low-frequency sounds, such as ticking clocks and passing trucks. Its structure creates multiple barriers between the two sound waves, preventing them from merging. As a result, your home or workplace becomes more peaceful and quiet.

Can You Use Regular Insulation for Soundproofing

You can use regular insulation to make your home quieter. It makes the room soundproof by soaking up sound waves instead of reflecting them, making it less noisy. Some types of insulation are very good at absorbing noise, like fiberglass and mineral wool.

How Thick Should Soundproof Foam Be?

There should be at least 2 inches of foam on each side of a wall for it to work. But if you want to block out a lot of noise or have a lot of space, you might need thicker panels. Both ways, soundproof foam is an excellent way to cut down on noise and make things quieter.

How Does Fiberglass Insulation Reduce Noise?

Soundproofing with fiberglass insulation is standard in homes and businesses. Fiberglass comprises millions of tiny fibers that act as a “cushion” to absorb strong vibrations, like those caused by loud music. As long as it’s appropriately installed, fiberglass insulation can help dampen sound transmission through walls and ceilings.

Is Thicker Sound Deadening Better?

Thicker sound deadening can help muffle noise and stop sound waves from spreading through space. It also makes it harder for sound waves to bounce around a room, making the sound duller.


So, is R13 insulation good for soundproofing? Unfortunately, the answer to that question is a little complicated. It depends on your soundproofing needs and how well your home is insulated.

Meanwhile, if you only need basic soundproofing and your home isn’t overly insulated, using R13 insulation may be a good option.
