Fiberglass Batts Insulation

What is fiber glass? Despite what the name would suggest, fiber glass isn’t actually a form of glass, but it is actually a type of plastic. However, the plastic is reinforced through glass fibers, thus leading to the name. Overall, fiber glass generally uses a very fine woven structure which helps contribute to its numerous insulating properties.

It is most commonly available as a sheet, but if you have been looking for fiber glass for acoustic purposes, acoustic panels made from fiber glass can also be available.

Is Fiber Glass Good for Acoustics?

At this point, we’ve mentioned fiber glass for acoustics – but how good actually is it? Well, it’s not always directly clear how effective fiber glass is for acoustic purposes since it’s not directly designed with this in mind. However, fiber glass offers numerous insulating properties for heat control, so it’s not a huge stretch to assume that fiber glass might also be good for sound control.

But is this the case? Well, yes! While fiber glass isn’t the most effective material on the market for sound absorption, it’s very close – all the while delivering almost unbeatable value for money. It’s also easy and practical to work with, making it easy to see why so many people use fiber glass for their property’s sound insulating needs.

Overall, when considering the noise reduction coefficient, fiber glass is exceptionally effective. It scores (as standard) around 0.90 on the scale out of a maximum of 1.0. As such, there’s genuinely not much room for fiber glass to improve in terms of its sound absorption properties!

The only real drawback here is that fiber glass isn’t overly effective for blocking out sound. As such, if you need a completely soundproof room, it may be worth considering a thick wall of fiber glass, or pair it with other sound absorbing options.

Remember: you don’t need to be limited only to your property’s walls, either. You can also use fiber glass on the ceilings and floors in your property, making it even more effective.


1. Fire protection and impact resistance: Class A fire protection rating; as the glass fiber cotton is a slender fiber, the overall strength of the structure is high, the tensile strength and shock resistance are excellent, no matter whether it is used for a long time or not, it will not loosen or scatter.
2. Heat preservation and environmental protection: Fiber glass has excellent heat preservation performance, with quartz sand and colorless glass as the main raw materials, high-quality green building materials, which can be recycled and reused.
3. Chemical and acoustic properties: Fiber glass has a porous structure inside, good dimensional stability, and excellent sound-absorbing performance; it is hardly affected by high temperature, rain, sunlight, PH value and other factors, which greatly improves the comfort of the indoor environment Spend.
4. Air permeability and water resistance: Porous and open structure, good stability and good air permeability, which can effectively help indoor moisture diffusion, reduce the possibility of mold growth, and help prolong the service life in living buildings.
5. Self-weight: Fiber glass has good sound insulation performance and low density, which meets the requirements of energy saving and improves construction efficiency.
6. Application: wall, ceiling, interior wall filling (sound absorption, heat insulation, shock absorption).
