Spray Foam vs Batt Insulation Pros and Cons

Speaking of spray foam vs batt insulation, which one do you consider as the best one for your walls? Well, it may be difficult to choose. You can, however, draw comparisons between the two. So, to make your decision easier, review the information provided below.

Spray Foam vs Batt Insulation Pros and Cons

Generally, spray foam has a few types. So does the batt insulation. Knowing those facts, the comparison of spray foam vs batt insulation below will not cover up all those types. Yet, in rather to few instances, Examples of spray foam are open and closed cell spray. While, for batt insulation, an example is sheep’s wool.

  • The Advantages and Disadvantages of Open-Cell Spray Foam

This spray can expand after spraying to cover gaps, fissures, and crevices. Unfortunately, the low-density one has an R-value which begins at 3.6 per inch. This is sufficient for mild regions, but not recommended for colder climates.

This is useful for opening spaces and will never settle. When it dries and sets, it forms an unbreakable, air-tight seal.

Furthermore, this kind of spray is watertight. Because it is impermeable to water, it inhibits the growth of mold and mildew and bacteria.

On the downside, it does not always fill the slightest gaps. This spray foam may cause water problems for homes in some cases because empty spaces might leak.

  • What Are The Advantages And Disadvantages Of Sheep’s Wool Batt Insulation?

Wool may survive for years and can be recycled when it is no longer useful.

Wool batts require a part of the energy needed to produce fiberglass batts.

It is permeable and can capture and expel water continuously. It may collect up to 30% of its volume in humidity before losing its thermal characteristics.

The fact that it has a poor R-value is its biggest downside. Wool is also susceptible to insects, particularly moths. Furthermore, wool insulation batts cost more than fiberglass batts.

Spray Foam VS Batt Insulation Summary

Spray foam

Below, you can take a look at some pros and cons of spray foam.

  • Pros
    • The most excellent density of any insulating material was produced. A separate vapor barrier is not required with closed-cell foam.
  • Cons
    • The installation emits hazardous gasses.
    • Leaks quickly through unprotected joints and holes, causing havoc.
    • A specialist subcontractor with specific training, gear, and expertise is required.
    • Far more costly than other types of insulation.

Batt Insulation

Well, you can take a look at some pros and cons of batt insulation below.

  • Pros
    • Cheap and simple to install
    • The optional face serves as a vapor barrier.
  • Cons
    • May irritate the skin, eyes, and lungs, leading to pulmonary problems.
    • Poor installation practices might degrade performance.
    • Temperature distribution through structural parts is hard to prevent.

Spray Foam VS Batt Insulation: Soundproofing

Is spray foam insulation worth it? Or, is batt insulation worth it? Especially for soundproofing? Due to the materials, spray foam and batt insulation can compete with one another.

Ultimately, the best solution is to utilize batts and, if feasible, seal them with an open-cell spray foam barrier. A dual component is the same as “flash and batt.” The STC of rigid fiberglass batts is approximately 44, equivalent to sound-absorbing fibrous material and superior to any insulating foam.

When rigid batt insulation is unavailable, foam is usually more effective at soundproofing than other types of fiberglass insulation. But still, batt insulation can absorb audio more uniformly, so although the STC rating appears lower, they are quite a better choice for soundproofing.

So, those are some explanations about spray foam vs batt insulation. Make sure to conduct a consultation with a professional before doing either one of them.
