Why Fiberglass?

Fiberglass offers a lightweight, durable alternative to stainless steel, wood, or concrete in a broad spectrum of industries and applications. As an extremely versatile material, the potential use cases for fiberglass are virtually limitless. This page will lay out some of the primary benefits of fiberglass to help design engineers make informed decisions during the material selection process.

Advantages of Fiberglass

When considering fiberglass as a material for your design, consider the following advantages:


Unlike many competitive materials, fiberglass won’t corrode, degrade, or rust in harsh or wet environmental conditions. Similar performance from metal would require an exotic or expensive material, potentially with additional coatings. Even a coated steel may begin to corrode within six months in the right environment, which means it would require frequent replacement. Fiberglass will not continuously expand and contract when exposed to heat and cold in the way that competitive materials will, which mitigates the risk for wear and cracking over time.

At Virtual Polymer Compounds (VPC), we have specific resins available to impart targeted properties into your fiberglass solution. We can improve resistances to salt, heat, and more. Because of its durability, fiberglass material requires little or no maintenance over its lifetime.

Why Fiberglass?


Fiberglass is a lightweight material with a high strength-to-weight ratio, making it ideal for reducing weight in automobiles, aircraft, and a variety of other machinery and equipment where total weight is a factor. Fiberglass easily molds into a wide variety of shapes in a similar manner to plastic, which makes it highly customizable and well-suited to creating unique components. This capability virtually eliminates the need for any secondary finishing or processing.

VPC can fully customize any standard product within our catalog or assist you in developing a wholly unique fiberglass design to meet your needs.


The safety benefits provided by fiberglass exceed what can be found in most other materials. Fiberglass won’t conduct heat or electricity, which reduces the risk of operator injury when using fiberglass housings and parts. The material also resists corrosives and chemicals and can be fabricated using non-porous resins that grant antimicrobial properties. The lightweight nature of fiberglass also makes it more ergonomic by putting less strain on employees and machinery when lifting.



When using engine or equipment housings made of fiberglass, the sound absorption properties of fiberglass help to significantly reduce the decibel level of the machinery. Incorporating fiberglass housings and casings into equipment reduces the risk of long-term hearing damage and other risks to equipment operators and bystanders.


The color options for fiberglass are near limitless. The color is incorporated into the fiberglass during the manufacturing process, which means that the color will never fade or chip over time.


As a durable and long-lasting material, fiberglass housings and components gain economies of scale. With virtually no maintenance needs and long service life, fiberglass helps to eliminate waste and defray its initial cost over time.
