The global fiberglass market is witnessing steady expansion due to rising demand across the automotive, construction, wind energy, and electrical & electronics industries. Fiberglass—composed primarily of fine glass fibers—is valued for its high strength-to-weight ratio, corrosion resistance, thermal insulation, and electrical non-conductivity. The growth of lightweight composites in the automotive and aerospace sectors to improve fuel efficiency and reduce emissions is a key driver. Additionally, global infrastructure development—especially in Asia-Pacific and the Middle East—fuels demand for fiberglass-based building materials such as rebar, insulation, and panels.

One of the major trends shaping the market is the rising use of fiberglass in renewable energy, particularly wind energy. With wind turbine blades requiring strong, lightweight, and durable materials, fiberglass is preferred for rotor blade manufacturing. For instance, Vestas and Siemens Gamesa use fiberglass composites in their wind turbine components. Furthermore, as the electric vehicle (EV) industry scales up, fiberglass is increasingly used in battery enclosures and underbody panels for insulation and safety. Sustainability also plays a growing role, as companies develop recyclable fiberglass materials and improve energy efficiency during manufacturing. This convergence of high-performance and green material demand is expected to reinforce fiberglass as a critical industrial material through 2033.

Fiberglass Market Trend

Demand for lightweight automotive composites

The rising global focus on lightweight vehicle design to enhance fuel efficiency and meet stringent emissions standards is a significant driver of fiberglass demand. The International Energy Agency (IEA) states that automotive emissions must be cut by over 50% by 2035 to meet net-zero targets. As automakers strive to reduce vehicle weight without compromising safety or durability, fiberglass-reinforced composites are increasingly used for body panels, bumpers, dashboards, insulation, and battery enclosures in electric vehicles (EVs).

Compared to traditional steel, fiberglass composites can reduce component weight by up to 30–40% while offering better design flexibility and corrosion resistance. Automotive OEMs such as BMW, Toyota, and Tesla are incorporating fiberglass-reinforced plastics in their vehicle platforms. I.

Moreover, regulatory pressure from the European Union’s Euro 7 standards and the U.S. EPA's new fuel efficiency rules, enforced starting in 2025, will accelerate the adoption of composite materials, including fibreglass. This makes the material crucial in aligning with industry sustainability goals, contributing to increased market penetration.

Fiberglass Market Growth Factor

Expansion of fiberglass use in wind energy

The use of fiberglass in wind energy is one of the most transformative trends in the market. Fiberglass-reinforced plastics (FRP) are extensively used in manufacturing wind turbine blades due to their lightweight, high tensile strength, and corrosion resistance. According to the Global Wind Energy Council (GWEC), global wind capacity installations reached 117 GW in 2024, with over 80% of rotor blades composed of fiberglass-reinforced composites. The push toward larger, more efficient wind turbines, such as those exceeding 100 meters in blade length, further fuels demand for advanced fiberglass materials with higher strength-to-weight ratios. Leading companies like Owens Corning and Jushi Group are innovating in high-modulus glass fiber to meet the specific structural requirements of offshore and high-capacity turbines.

• For instance, in November 2024, Siemens Gamesa secured a $1.3 billion contract to supply turbines for the East Anglia TWO offshore wind farm, utilising advanced fiberglass composites to enhance blade efficiency and reduce weight.

As countries like the U.S., India, and China increase their wind power capacity targets for 2030 and beyond, fiberglass consumption in this sector is expected to show above-average growth, cementing its role in the renewable energy value chain.

Market Restraint

Environmental concerns & recycling limitations

While fiberglass offers numerous performance benefits, its environmental impact and end-of-life challenges present significant restraints. The production of fiberglass involves high energy consumption and emits CO₂ and other particulates, particularly during the melting phase of raw materials. According to a 2024 European Environment Agency (EEA) report, fiberglass production emits approximately 1.5 tons of CO₂ per ton of glass fiber, contributing to industrial emissions in key manufacturing countries.

Additionally, fiberglass is difficult to recycle due to its thermoset matrix, which cannot be remelted. Current recycling options—such as mechanical grinding for filler use or energy recovery—are inefficient and economically unattractive. Landfilling remains the primary disposal method, raising concerns over long-term sustainability and environmental regulation compliance.

Moreover, downstream users' consumer awareness and sustainability commitments (like automotive and construction firms) are prompting a shift toward more eco-friendly materials. If not addressed, these limitations may curb fiberglass demand in favor of more circular alternatives like natural fiber composites or thermoplastic-based solutions.

Market Opportunity

Infrastructure and urbanisation in emerging economies

One of the strongest opportunities for the fiberglass market lies in the rapid urbanisation and infrastructure development in emerging economies across Asia-Pacific, Latin America, and Africa. With governments investing heavily in housing, transportation, and industrial infrastructure, demand for corrosion-resistant, lightweight, and durable materials like fiberglass is rising. The Indian government, for example, allocated over USD 140 billion for infrastructure development in its 2025 Union Budget, focusing on smart cities, metro rail networks, and roadways. Fiberglass rebar and panels are increasingly used in bridges and coastal construction due to their resistance to corrosion compared to steel. Similarly, China’s Belt and Road Initiative (BRI) continues to create demand for industrial and infrastructural composites, with fiberglass gaining traction in utility poles, pipelines, and prefabricated building materials. Companies are capitalising on these.

• For instance, in September 2024, China Jushi expanded its Egyptian fiberglass production facility, increasing annual capacity to 340,000 metric tons.This expansion aims to meet the growing demand for fiberglass in infrastructure projects across the Middle East and Africa, highlighting the material's role in supporting sustainable development in emerging markets.

As urban populations grow and infrastructure becomes more resilient and sustainable, fiberglass is a critical material in next-generation development.
