The s-grade high-strength glass fiber market size has grown strongly in recent years. It will grow from $3.05 billion in 2024 to $3.29 billion in 2025 at a compound annual growth rate (CAGR) of 7.9%. The growth during the historic period can be attributed to the increasing use of electrical and electronics insulation applications, greater adoption in the marine and shipbuilding sectors, rising demand from sporting goods and recreational equipment, stricter environmental regulations promoting lightweight materials, and expanding applications in household appliances and consumer products.
The s-grade high-strength glass fiber market size is expected to see strong growth in the next few years. It will grow to $4.43 billion in 2029 at a compound annual growth rate (CAGR) of 7.7%. The growth in the forecast period is expected to be driven by the rising demand for lightweight materials in the automotive industry, increased use of glass fibers in aerospace applications, growth in the wind energy sector, expansion of the construction industry, and higher demand for durable and corrosion-resistant materials. Key trends during the forecast period include technological advancements that enhance fiber strength and durability, improved fire resistance properties of S-grade glass fibers, progress in manufacturing techniques, enhanced mechanical properties that boost product performance, and the substitution of traditional materials such as metals with composites.
The increasing development of infrastructure is expected to drive the growth of the S-grade high-strength glass fiber market in the future. This growth is fueled by rising urbanization and the demand for improved transportation, housing, and public services to accommodate expanding populations. S-grade high-strength glass fiber, also known as S-glass (or S-2 glass in the U.S.), is a specialized glass fiber with superior mechanical properties compared to conventional E-glass (electrical-grade glass fiber). It offers higher tensile strength, better thermal stability, and enhanced fatigue resistance, making it highly valuable for infrastructure projects. For example, a report from the UK’s Office for National Statistics in July 2024 showed that total general government spending on infrastructure rose by 9.6% in 2022 compared to 2021, reaching $34.9 billion (£26 billion) at current prices. Thus, the expansion of infrastructure development will significantly support the growth of the S-grade high-strength glass fiber market.
The growth of the automotive sector is also expected to boost the S-grade high-strength glass fiber market in the coming years. This sector involves the design, development, manufacturing, marketing, and sales of motor vehicles and related components. The automotive industry is expanding due to rising consumer demand for electric vehicles, which is driven by increasing environmental awareness and government incentives promoting sustainable transportation. S-grade high-strength glass fiber (commonly referred to as S-glass or S-2 glass) is widely used in the automotive industry to improve structural performance, safety, and durability while reducing weight. Compared to standard E-glass, it offers superior tensile strength, stiffness, impact resistance, and thermal stability. For instance, according to the European Automobile Manufacturers Association in January 2025, new car registrations across the European Union increased by 5.1% in 2024, with Spain experiencing a strong growth of 28.8%, while France saw a smaller rise of 1.5%. Consequently, the expanding automotive sector will contribute to the growth of the S-grade high-strength glass fiber market.
Leading companies in the S-grade high-strength glass fiber market are developing advanced products such as rovings, which allow precise control of fiber orientation in composite manufacturing. Rovings consist of bundles of continuous glass fibers used as reinforcement in composites. For example, in April 2025, AGY Holdings Corp., a U.S.-based supplier of high-performance glass fibers, introduced a new lightweight single-end S2 Glass roving. This product offers exceptional strength, stiffness, and impact resistance, making it suitable for advanced composite applications where weight and durability are critical. Its design enables the production of thinner, lighter laminates while delivering superior mechanical properties compared to traditional rovings. The material enhances ballistic protection and impact absorption and improves radar transparency due to a lower dielectric constant. Additionally, it supports higher operating temperatures, better fatigue resistance, and integrates seamlessly into existing manufacturing processes through advanced fiber-matrix bonding technology.
