Mineral Wool Insulation Market Report 2026

The mineral wool insulation market size has grown strongly in recent years. It will grow from $20.86 billion in 2025 to $22.1 billion in 2026 at a compound annual growth rate (CAGR) of 6%. The growth in the historic period can be attributed to rising demand for thermal and acoustic insulation, increasing use in construction and automotive sectors, growing industrial applications, expansion of high-temperature insulation needs, adoption in building retrofits.

The mineral wool insulation market size is expected to see strong growth in the next few years. It will grow to $27.57 billion in 2030 at a compound annual growth rate (CAGR) of 5.7%. The growth in the forecast period can be attributed to increasing production of rigid and flexible mineral wool boards, growth of multi-layer and fire-resistant insulation, rising application in aerospace and marine sectors, development of energy-efficient insulation solutions, expansion in commercial and industrial building applications. Major trends in the forecast period include adoption of AI-based manufacturing processes, integration of iot for product monitoring, development of sustainable and recycled mineral wool solutions, implementation of industry 4.0 in insulation production, digitalization of supply chains for insulation products.

The increase in construction activities is expected to drive the growth of the mineral wool insulation market going forward. Construction activity refers to the launch of new housing and commercial projects, including single-family units, multifamily buildings, and business facilities, influenced by consumer demand and broader economic conditions. Construction activity is rising due to rapid urbanization and growing infrastructure investments supported by government initiatives and economic development. Mineral wool insulation supports construction by improving fire safety, strengthening building structure, and helping meet regulatory compliance requirements. For example, in June 2025, Eurostat, a Luxembourg-based statistical office of the European Union, reported that construction production in April 2025 increased by 3% in the euro area and by 2.5% in the EU compared with April 2024. Therefore, the rise in construction activities is contributing to the growth of the mineral wool insulation market.

Key companies in the mineral wool insulation market are focusing on innovative products such as 32 lambda glass mineral wool insulation slabs to boost thermal performance, comply with stricter energy efficiency regulations, and meet the rising demand for sustainable, high-performance building materials. The 32 lambda glass mineral wool insulation slab offers low thermal conductivity of 0.032 watts per meter kelvin (W/mK), designed to deliver superior energy efficiency and satisfy advanced building standards. For instance, in May 2023, Knauf Insulation, a Germany-based insulation manufacturer, launched OmniFit Slab 32 - the first 32 lambda glass mineral wool insulation slab designed for light steel frame systems (SFS) in rainscreen façades and other external wall assemblies. It is suitable for high-rise residential buildings over 11 m and 18 m and complements the Rocksilk RainScreen Slab to meet stringent fire safety, thermal, and acoustic requirements, including Building Regulations Part E (40 RwdB). As part of the OmniFit range, it provides excellent thermal conductivity (0.032-0.04 W/mK), high acoustic performance, and sustainability benefits such as up to 80% recycled content, reduced embodied carbon compared to rock mineral wool, and efficient packaging that lowers transport emissions.

In October 2024, Knauf Group, a Germany-based building materials company, acquired Texnopark’s Rock Mineral Wool insulation business for an undisclosed amount. This acquisition aims to expand Knauf’s insulation operations into Central Asia by leveraging Texnopark’s advanced low-carbon rock mineral wool production facility to meet the region’s increasing demand for sustainable and energy-efficient building materials. Texnopark LLC is a mineral wool insulation manufacturer based in Uzbekistan.

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 insulation market by increasing costs for imported glass wool, rock wool, slag wool, and high-temperature insulation products. Automotive, construction, industrial appliances, and building sectors in Asia-Pacific, North America, and Europe are most affected due to import dependencies. However, tariffs are driving localized manufacturing, promoting eco-friendly mineral wool production, and enhancing supply chain resilience while stimulating innovation in high-performance insulation materials.

This mineral wool insulation market research report delivers a complete perspective of everything you need, with an in-depth analysis of the current and future scenarios of the industry.

Mineral wool insulation is a thermal and acoustic insulating material produced from natural rock or recycled slag. It is created by melting these raw materials at high temperatures and spinning them into fibrous mats. Its main function is to minimize heat transfer and reduce sound within buildings and industrial systems.

The primary types of mineral wool insulation include glass wool, rock (or stone) wool, slag wool, and others. Glass wool is made by melting glass and spinning it into fibers, providing thermal, acoustic, and fire insulation for buildings and industrial uses. Available products include boards, blankets, loose wool, panels, customized shapes, and more, serving diverse end-user industries such as automotive and transportation, building and construction, industrial and consumer appliances, among others.North America was the largest region in the mineral wool insulation market in 2025.
