The mineral wool insulation board market size is expected to see strong growth in the next few years. It will grow to $12.94 billion in 2030 at a compound annual growth rate (CAGR) of 6.6%. The growth in the forecast period can be attributed to increasing innovation in multi-layer and flexible boards, expansion of rigid and high-performance boards, rising adoption in aerospace and marine applications, growth in fire-resistant and thermal boards, development of sustainable and eco-friendly insulation products. Major trends in the forecast period include deployment of high-density and acoustic rigid boards, expansion of flexible mineral wool insulation panels, integration of iot for performance monitoring, adoption of fire-resistant insulation solutions, development of thermal insulation boards for industrial applications.

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 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 driving 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 October 2024, Knauf Group, a Germany-based supplier of building materials including energy-efficient insulation and system solutions, acquired the rock mineral wool insulation business of Texnopark LLC for an undisclosed amount. Through this acquisition, Knauf aimed to expand its insulation operations into Central Asia and enhance its manufacturing capacity for low-carbon mineral wool board production to support sustainable construction applications. Texnopark LLC is an Uzbekistan-based manufacturer of rock mineral wool insulation materials used in modern, energy-efficient building systems.

Major companies operating in the mineral wool insulation board market are Knauf Insulation GmbH, Owens Corning, Kingspan Group plc, Xella International GmbH, Rockwool International A/S, Johns Manville Corporation, Armacell GmbH, Luyang Energy-Saving Materials Co.

The mineral wool insulation board 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 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.Asia-Pacific was the largest region in the mineral wool insulation board market in 2025.
