Mineral Wool Market Report 2026

The mineral wool market size has grown strongly in recent years. It will grow from $15.77 billion in 2025 to $17.07 billion in 2026 at a compound annual growth rate (CAGR) of 8.3%. The growth in the historic period can be attributed to increasing construction activities, rising demand for thermal insulation, early adoption in industrial insulation, growing awareness of fire safety standards, expansion of transportation sector requirements.

The mineral wool market size is expected to see strong growth in the next few years. It will grow to $22.86 billion in 2030 at a compound annual growth rate (CAGR) of 7.6%. The growth in the forecast period can be attributed to rising focus on sustainable building materials, growing need for energy efficiency compliance, increasing use in acoustic insulation applications, expansion of green building certifications, higher investment in industrial refurbishment projects. Major trends in the forecast period include growing demand for energy-efficient insulation materials, rising use of high-performance fire-resistant insulation, increasing adoption of durable and weather-resistant insulation solutions, expansion of mineral wool in industrial and high-temperature applications, growing preference for acoustic and vibration control insulation.

The increasing demand in the construction sector is expected to drive the growth of the mineral wool market going forward. Construction involves the planning, designing, and building of physical structures, infrastructure, or facilities. Mineral wool enhances energy efficiency, fire safety, durability, chemical resistance, indoor comfort, and overall building performance. For example, in May 2025, the Australian Bureau of Statistics (ABS), an Australian-based government agency, reported that in 2024 the construction industry grew steadily, with earnings up 6.3% and IVA increasing 8.6% from the previous year, driven by strong demand and higher output prices. Therefore, the rising demand for construction is fueling the growth of the mineral wool market.

Major companies in the mineral wool market are forming strategic partnerships to improve product performance, ensure strong physical properties, and maintain smooth production processes. UPM BioPiva lignin - a sustainable, cost-effective, and versatile material - acts as an ideal bio-based alternative to fossil-derived binders. For instance, in May 2023, UPM Biochemicals (Finland) partnered with URSA (Europe) to launch a new sustainable glass wool insulation using a bio-based binder made from UPM BioPiva lignin, a natural wood-based polymer. This innovation replaces traditional fossil-based synthetic resins, resulting in one of the most environmentally friendly insulation materials available. The development boosts energy efficiency, reduces CO₂ emissions in buildings, and represents a significant step toward greener construction materials. Overall, this partnership marks a disruptive advancement in insulation technology, strengthening the industry’s commitment to lowering carbon footprints and supporting sustainability.

In October 2024, Knauf Group, a Germany-based building materials company, acquired Texnopark’s rock mineral wool insulation business in Uzbekistan for an undisclosed amount. Through this acquisition, Knauf Group aims to support Uzbekistan’s strategic priority of promoting energy-efficient and well-insulated buildings, thereby advancing sustainable construction and energy savings. Texnopark is an Uzbekistan-based company that provides mineral wool products.

Note that the outlook for this market is being affected by rapid changes in trade relations and tariffs globally. The report will be updated prior to delivery to reflect the latest status, including revised forecasts and quantified impact analysis. The report’s Recommendations and Conclusions sections will be updated to give strategies for entities dealing with the fast-moving international environment.

Tariffs are influencing the mineral wool market by raising the import costs of raw materials such as basalt, slag, and manufacturing equipment, leading to increased pricing for glass wool, rock wool, and other mineral fiber products. Regions dependent on imported insulation materials primarily Asia-Pacific, Africa, and parts of Latin America face higher construction and industrial project costs. Nevertheless, tariffs may stimulate domestic mineral wool production, encourage local sourcing of raw materials, and drive investment in regional manufacturing capacity, creating long-term competitive advantages.

The mineral wool market research report is one of a series of new reports that provides mineral wool market statistics, including mineral wool industry global market size, regional shares, competitors with an mineral wool market share, detailed mineral wool market segments, market trends and opportunities, and any further data you may need to thrive in the mineral wool industry. This mineral wool market research report delivers a complete perspective of everything you need, with an in-depth analysis of the current and future scenario of the industry.

Mineral wool is a non-metallic, inorganic product primarily made from either stone or silica that has been heated to a high temperature and transformed into a molten state. Carefully curated raw materials are utilized in the manufacturing process. Mineral wool is valued for its excellent thermal insulation properties, helping to prevent heat transmission through building envelopes and thereby reducing the need for energy in room heating and cooling.

The primary types of mineral wool include glass wool, rock wool, and other variations. Glass wool, for instance, is an insulation material manufactured from glass fibers arranged using a binder into a texture similar to wool. Glass wool is known for being eco-friendly and highly effective, meeting the requirements of various applications in different industries. It is available in three forms such as board, blanket, and panel. Mineral wool is used by industries such as building and construction, industrial, transportation, and other end-use sectors.Asia-Pacific was the largest region in the mineral wool market in 2025.
