Top 10 Companies in the Wet‑Laid Glass Fiber Nonwoven Market (2026): Market Leaders Powering Global Construction and Filtration

MARKET INSIGHTS

Global Wet‑Laid Glass Fiber Nonwoven market size was valued at USD 1.29 billion in 2024. The market is projected to grow from USD 1.33 billion in 2025 to USD 1.71 billion by 2032, reflecting a CAGR of 3.50 % over the forecast period.

Wet‑Laid Glass Fiber Nonwovens are produced by suspending glass fibers in a water‑based slurry that is deposited onto a moving wire screen to form a uniform web. This method delivers lightweight, high‑strength mats with excellent dimensional stability, chemical resistance, and thermal insulation. Two main product forms exist: long glass fiber and short glass fiber, each engineered for distinct performance requirements.

Demand from construction and industrial filtration fuels the market’s steady expansion. The resurgence of construction activity in the Asia‑Pacific region drives use in roofing materials and plasterboard, while tightening environmental regulations worldwide boost the need for high‑efficiency filtration media. Major players such as Johns Manville and Owens Corning are expanding capacity and developing sustainable variants to capture these opportunities.
