There is a lot of sand on earth, making fiberglass a sustainable product. Rockwool insulation has a density of around 1.7 pounds per cubic . Loose fiberglass insulation has an STC of around 35-39. Application. Anything higher than that and it will start melting. Fiberglass filaments are packaged into rolls, while others are packaged into denser materials. Rockwool is eco-friendly, while fiberglass is biodegradable. We may receive compensation if you visit partners we recommend. Further, if you buy a 3-inch thick batt do not forget to multiply the R-value with the thickness. In addition, the sound insulation helps boost . This blown-in-blanket fiberglass system was specifically designed for closed cavity applications. As well, fiberglass is lighter and will puff out Roxul will stay crushed. 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. Continuing the example, in this case, the R-value will be 6. Definitely rockwool is easier to install yourself since its not dangerous to do so. Because of their various uses and structures, these materials cannot fall under only one category. In most other countries, the Sound Reduction index is used (SRI). ROCKWOOL Safe'n'Sound is a stone wool insulation for use in interior partitions of residential wood and steel stud construction where superior fire resistance and acoustical performance are required. Caulk all around the edges of the top and bottom plate, and where it meets the wall. But, due to its higher density, rockwool is more resistant 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 foota cost difference of up to 25% per square foot. Rockwool and fiberglass are both ecologically friendly compared to other building materials. 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. Fiberglass is also breathable due to its porous nature, so it is resistant to mold and mildew growth. This is not the case with rockwool, however, since its not carcinogenic and even though when handled some particles may become airborne, these are much heavier than the fiberglass particles and will drop to the floor in no time. Mineral Wool Insulation is Making a Comeback. Here's Why (DIY) Rockwool is more expensive than fiberglass. The narrative revolves around a researcher in the 1930s trying to vacuum seal glass blocks using a high-pressure jet which incidentally spewed out fiber-like threads of the glass. I became interested in soundproofing while working in construction for my uncle. Music production is a sensitive process, and sound insulation is an important factor in in-studio music recordings. Because of their similar application, the differences can be very confusing at first. But how effective is it really? Where rock wool can manage sounds up to 10 decibels, fiberglass controls noise vibrations in the range of 4 to 10 decibels. First you need to understand the differences between Soundproofing and Acoustic Treatment, STC Rating of Fiberglass vs Rockwool (Which one insulates the best), Flame Spread Rating and smoke development of Rockwool vs Fiberglass Insulation, differences between soundproofing and acoustic treatment, nowhere near as good as closed cell spray foam. Generally, though, you can freely pick either of the two for this metric; both fiberglass and Rockwool insulation are inorganic materials that dont contribute to (and even suppress) the invasion of fungi and insects within the walls they occupy.

Final Thoughts Fiberglass attracts mold, which can be a disease source, whereas rock wool repels mold growth. Consequently, the liquid transforms into elongated strands of fiber. Owens Corning 703 vs Rockwool. The fibers are spun out of glass melted at high temperatures and compressed and sold in form of long rolls or blankets. The main difference between rockwool and fiberglass for sound absorption is down to the frequency of noise they absorb. Sound loses some but not much energy as it passes through 3 1/2" of insulation nor and it doesn't make much difference if it is fiberglass vs mineral wool or acoustic vs thermal Insulation as long as it fills the cavity tightly. Cars look cleaner when getting out of the carwash tunnel. A standard R-15 rated Fiberglass insulation for a 4-inch wall will cost around $ 0.50 per square foot.

Rockwool vs. Fiberglass Insulation: What's the Difference? Rock wool appears to have a slight upper hand in that it is moisture resistant. Fiberglass filaments are long or short, and the quality of the product varies and can undergo additional processes to remove impurities to increase the quality level. The STC rating reflects the decibel reduction of noise that a partition can provide (1 STC is equivalent to 1dB reduction), where a higher number, or rating, equals better results, or overall attenuation. Adding interior insulation for soundproofing; worth it? While fiberglass is cheaper, Rockwool is more durable, absorbs sound much better, helps control temperature, and so much more. Rockwool vs Fiberglass: Deciding Between Similar Terms Fiberglass is made from glass, which is made from sand.

The biggest drawback would be that its not that great of a heat insulator since air can easily pass through it, which means that humidity will as well. Rock wool is made from rocks and is also known as mineral wool. Loose-fill cellulose has a fairly high NRC value of 0.80, while densely-packed cellulose boasts an outstanding 0.90 NRC. What is the best insulation for a home? - Ecohome Neither is flammable, and they dont sustain fire or help it spread either. Fiberglass can be added in layers to obtain a better effect. Rest assured , if you go with Thinsulate, it is also a sound absorber!

Inhaling microscopic fiberglass fibers can cause eye irritation, coughing, a sore throat and nose, and stomach irritation if swallowed. Now lets see how fiberglass and rockwool do as far as soundproofing goes: Also known as mineral wool, rockwool is literally what the word implies: Rock fibers (volcanic rock and slag) which are spun and then given a specific shape (batt, pipe and board forms). In addition to this, rockwool tends to settle once installed and a small air gap will form on top of it allowing sound, heat and cold to get through.
