Which absorbs more sound: rockwool or glasswool?
This is where problems arise in a home, so fiberglass is generally the preferred option. In a direct comparison of size and surface area, rockwool will always absorb more sound than glasswool.
What is glass wool insulation made of?
Simply put, glass wool insulation is made from glass that’s been spun into fibers and then formed into sheets using a binding agent. Thin layers are pressed together into a bigger sheet for greater strength and stability. Rockwool, also known as mineral wool, is essentially the same product. But instead of glass, it’s made from spun stone or silica.
How does rock insulation work?
Importantly, both of these products are primarily thermal insulators. They work by trapping small pockets of air between the fibers, and this is what provides the thermal insulation itself.
Is glass wool good for HVAC?
2. Insulating HVAC systems. One instance where glass wool comes out on top is for insulating pipes and HVAC systems. Commonly sold as pipe wrap (Amazon link), glass wool insulation is more flexible and so is perfect for wrapping around pipes and vents.
Does rockwool absorb sound?
As mentioned, rockwool and glasswool absorb sound waves. But for proper soundproofing, you’ll also want to add more mass and sound deadening materials. This will mean that the level of sound waves passing into the wall cavity is reduced in the first place, making any absorption techniques more effective.
