Where to Use Rockwool COMFORTBATT
Energy savings begin with a properly insulated attic and exterior walls but there are other applications that can make a big difference in your home's comfort. Insulating the exposed concrete walls in your basement and heated crawl spaces are effective ways to improve the energy efficiency of your home.
Rockwool
Insulation is easy to cut and install. Its unique stone wool composition, density, and friction-fit batts help you or your contractor prevent any gaps that can result in energy loss.

As the two most popular materials used for home insulation, it should be no surprise that rockwool and fiberglass are very good at preventing temperature leakage, which is measured with something called the R-value.
Since insulation batts are sold based on the R-value that they provide, a reliable way to measure the insulating ability of these materials is by noting the R values that they achieve at a specific thickness.
Given a benchmark thickness of 3.5 inches, a batt of Rockwool achieves an R-15 insulation value while fiberglass achieves an R-13 value, giving Rockwool about 15% better insulating ability over fiberglass at the same thickness.
Since insulators are, by nature, able to resist the flow of heat going through them, they should also have some ability to resist fire. Although there are some insulators out there (particularly cellulose) that are susceptible to igniting, both Rockwool and fiberglass have great fire resistance as both are non-combustible.
However, Rockwool insulation gains further points here thanks to its mineral-based construction, which gives it a much higher melting point than fiberglass.

Of course, homes have to deal with a lot more than just heat&#;during the colder and rainier parts of the year, the main issue instead becomes moisture, excessive amounts of which can damage the insulation or the surrounding frame.
Thankfully, both Rockwool and fiberglass insulation have good resistance to water damage, which can even be improved further if you buy faced insulation, which includes a layer of foil or a paper-like material on the outer layer to serve as a sort of vapor barrier.
It should also be noted that the higher density of Rockwool insulation can make it more resistant to moisture buildup as there are fewer pockets of air inside the batt for moisture to occupy.
Although they are not and should not be your first priority when shopping for insulation, having resistance to other things is still generally nice to have.
For home insulation, there are some things you would want to take into consideration&#;specifically that of insect, mold, and mildew resistance.
Generally, though, you can freely pick either of the two for this metric; both fiberglass and Rockwool insulation are inorganic materials that don&#;t contribute to (and even suppress) the invasion of fungi and insects within the walls they occupy.
(Just for reference, cellulose insulation is an organic material, which means fungi and insects can feed on it if it is not given any additional treatment.)
Another consequence of the way insulation works is that it can also provide some level of acoustic deadening (which is distinctly different from soundproofing, as they do not provide full soundproofing).
While some sources will tell you that Rockwool provides better acoustic deadening than fiberglass, this is actually not true in all cases because of how sound and sound deadening works.
Now, we&#;ll spare you the complicated science that goes on behind the scenes and give you the summary.
When it comes to sound deadening, the higher density of Rockwool insulation makes it good at blocking out lower-frequency noises like heavy thuds. Meanwhile, higher-frequency noises like claps are better blocked out by the looser composition of fiberglass insulation batts.
Now, it is one thing for insulation to perform better than its competitor; however, all of its advantages become immediately irrelevant when the insulation can&#;t be installed in the first place.
And it is here that we find one of the reasons behind the popularity of fiberglass in homes&#;since they are much lighter and less dense than Rockwool by volume, fiberglass is much easier to install.
Fiberglass is pliable enough to be worked around difficult spaces, such as around pipes and in crawl spaces, and batts of the stuff could also be easily cut to fit specific sizes and shapes.
By contrast, Rockwool insulation batts are a lot more rigid, owing to their density, which makes them more suited to spaces with fixed shapes so they don&#;t have to be cut or bent at great effort.
When it comes to insulating products, their warranty is usually treated like that of any other product&#;most manufacturers will have a 1- to 3-year warranty against production defects on their insulation batts.
Of course, longevity is a very different&#;but very important&#;quality you will need to take into consideration.
Based on our experience and analysis, the typical lifespan of Rockwool insulation is about 30 years before they will need to be replaced. By comparison, fiberglass is generally expected to last for about 25 years; however, fiberglass insulation can and does collapse and flatten over time, which can lower its insulating ability faster than Rockwool.
Last but definitely not the least of your concerns is the cost of having either as your home insulation.
Depending on where you source your insulation batts and the pricing of your contractor (which itself can vary by a significant margin depending on their skill level and the complexity of the project), Rockwool is generally more expensive than fiberglass.
Gathering info from various retailers and contractors, you can expect to pay about $0.50 to $0.60 to install one square foot of fiberglass, while Rockwool costs about $0.60 to $0.75 per square foot&#;a cost difference of up to 25% per square foot.
