Mineral Wool Insulation Board Market Report 2025

The mineral wool insulation board market size has grown strongly in recent years. It will grow from $8.75 billion in 2024 to $9.37 billion in 2025 at a compound annual growth rate (CAGR) of 7.1%. The growth observed during the historic period can be credited to the rising demand for energy-efficient buildings, expanding construction activities, stricter fire safety regulations, increased adoption of green building certifications, and the expansion of industrial infrastructure and power plants.

The mineral wool insulation board market size is expected to see strong growth in the next few years. It will grow to $12.15 billion in 2029 at a compound annual growth rate (CAGR) of 6.7%. Growth in the forecast period is expected to be driven by increasing investments in retrofitting and renovation, heightened focus on sustainable construction and circular economy principles, more government incentives and subsidies, accelerating urbanization alongside the rapid development of smart cities, and the implementation of net-zero building mandates. Key trends during this period include the development of lightweight composite boards, creation of bio-based binders, integration with building information modeling, combining acoustic and thermal properties, and innovations in surface coatings.

The rising construction activities are expected to drive the growth of the mineral wool insulation board market in the coming years. Construction activities encompass the processes involved in building, modifying, or demolishing structures such as buildings, roads, bridges, and other infrastructure. The increase in construction activities is mainly attributed to rapid urbanization, as growing populations in urban areas create greater demand for residential buildings, commercial spaces, and infrastructure development. Mineral wool insulation board supports construction activities by providing superior thermal and acoustic insulation, which improves energy efficiency and building performance. For example, in July 2023, according to the Australian Bureau of Statistics, an Australia-based government agency, the number of dwellings under construction rose to 240,813 in the March quarter of 2023 from 240,065 in 2022. Of these, new houses amounted to 103,778 in 2023, up from 101,240 in the previous year. Hence, the increase in construction activities is boosting the growth of the mineral wool insulation board market.

Leading companies in the mineral wool insulation board market are concentrating on developing innovative products, such as lightweight mineral wools, to improve energy efficiency and simplify installation in modern construction projects. Lightweight mineral wools are insulation materials made from natural or synthetic minerals designed to be less dense, providing excellent thermal and acoustic insulation while reducing the overall structural load. For instance, in May 2023, Isover, a France-based company specializing in thermal, acoustic, fire, and industrial insulation solutions, introduced QTech, an advanced lightweight mineral wool engineered for medium-temperature industrial applications. This product delivers outstanding thermal insulation with low thermal conductivity and a shot-free composition, preventing thermal bridging and enhancing energy efficiency for applications up to 300°C. It is lightweight, easy to install, non-combustible, environmentally sustainable, and provides effective acoustic insulation with long-lasting performance without causing corrosion.

In January 2022, Saint-Gobain S.A., a France-based materials and solutions manufacturer, acquired Rockwool India from the Alghanim Group for an undisclosed sum. Through this acquisition, Saint-Gobain aims to strengthen its position in India’s insulation market by expanding its stone wool product range and enhancing local manufacturing capabilities. Rockwool India Pvt. Ltd. is an India-based company that manufactures stone wool (mineral wool) insulation boards.

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.

The rapid escalation of U.S. tariffs and the resulting trade tensions in spring 2025 are significantly impacting the construction sector, particularly in materials procurement and project costs. Higher duties on imported steel, aluminum, lumber, and machinery have driven up expenses for builders, contractors, and infrastructure developers, leading to increased project bids and delayed timelines. Construction equipment manufacturers face similar challenges, with tariffs on essential components and raw materials inflating production costs and squeezing margins. Additionally, retaliatory tariffs in international markets have curtailed exports of U.S.-made construction equipment and materials, further affecting profitability. The sector must now prioritize local sourcing, modular construction techniques, and supply chain diversification to control costs and ensure project viability amid ongoing trade uncertainties.

Mineral wool insulation board is a rigid or semi-rigid panel composed of mineral fibers, typically sourced from natural rock (stone wool) or recycled slag from steel manufacturing (slag wool). These boards are engineered to deliver superior thermal insulation, soundproofing, and fire resistance for building and industrial uses. Commonly applied in wall systems, roofs, floors, and industrial equipment, mineral wool insulation boards are prized for their outstanding energy efficiency, acoustic control, and fire safety properties.

The primary product types of mineral wool insulation board include rigid mineral wool insulation board and flexible mineral wool insulation board. Rigid mineral wool insulation board is a dense, solid panel made from spun mineral fibers (such as stone wool or slag wool) that offers excellent thermal, acoustic, and fire-resistant insulation for walls, roofs, floors, and industrial applications. The key applications span residential, commercial, and industrial buildings, with distribution occurring through various channels such as direct sales, distributors, and online platforms. Major end-use industries comprise construction, automotive, marine, aerospace, and electrical sectors.
