Fiberglass has been considered one of the premiere thermal insulators for decades. Fiberglass itself was developed in the 1930s and within just a few years became widely used for both residential and commercial applications.

At B&W Fiberglass, we’ve been innovating the myriad uses for fiberglass for over 25 years. Our clients run the gamut, from construction to manufacturing, and they’re always looking for new ways to harness the innate capabilities of fiberglass materials.

So, why is fiberglass so ideally suited for insulation?

Fiberglass Offers Very High R-Values

Medium- and high-density fiberglass can easily offer insulative capabilities of up to an R-38 value for tight spaces. Fiberglass itself has a very low coefficient of thermal expansion and high thermal conductivity. Even at incredibly high temperatures, fiberglass retains a significant amount of strength. 

 

Fiberglass Can be Environmentally Friendly

Many fiberglass insulation products are made from at least partially-recycled materials. In addition, fiberglass’ basic component (sand) is considered a naturally renewable resource by the EPA. Because fiberglass is so effective as an insulator, its use can have energy-saving effects for an entire structure, reducing the need for HVAC.

 

Fiberglass is Cost-Effective

Commercially, fiberglass has always been one of the least expensive forms of insulation. Compared to other synthetic and natural insulation products, it’s more prolific and less expensive to produce. It’s relatively easy to install; newer generation fiberglass materials offer additional insulative properties and/or thresholds albeit with a slightly more expensive price point.

 

Fiberglass Insulation Can be Installed Over Existing Insulation

Some insulative materials require removal of the underlying insulation in order to work properly. Fiberglass, both batting and loose-fill, can effectively be installed directly on top of existing insulation. Because it efficiently fits into crevices, it’s an excellent choice for filling in small cracks and gaps in a structure.

 

Fiberglass Doesn’t Settle Over Time

Unlike some blow-in insulation products, fiberglass batting won’t settle much over time. This means its R-value stays consistent, retaining its insulative capabilities. It also won’t absorb water, making it ideal for spaces that tend to have issues with moisture or humidity.


B&W Fiberglass is a leader in glass fiber technology. As one of the most well-known names in fiberglass manufacturing and distribution in the world, B&W continues to innovate the ways in which glass fiber is used for residential, commercial, and developmental applications.

While insulation has long been fiberglass’ best-known application, glass fiber materials are used in almost every industry on the planet. From recreation to automotive, energy to architecture, fiberglass touches the things we see and utilize every single day.
