Glass Wool Acoustic Insulation Market Report 2025

The glass wool acoustic insulation market size has grown strongly in recent years. It will grow from $3.53 billion in 2024 to $3.78 billion in 2025 at a compound annual growth rate (CAGR) of 7.3%. The growth observed during the historic period can be credited to the surge in construction activities, heightened demand for thermal and acoustic insulation, increased awareness regarding energy efficiency, rapid urbanization, and greater adoption within commercial buildings.

The glass wool acoustic insulation market size is expected to see strong growth in the next few years. It will grow to $4.95 billion in 2029 at a compound annual growth rate (CAGR) of 6.9%. The growth in the forecast period is expected to be driven by a stronger focus on green building standards, the rising renovation of aging buildings, growing demand for sustainable insulation materials, expansion of the industrial sector, and stricter government regulations on energy efficiency. Key trends anticipated during this period include advancements in insulation manufacturing technologies, innovations in lightweight acoustic materials, the integration of glass wool with composite insulation systems, the development of eco-friendly glass wool products, and the adoption of smart insulation solutions.

The increase in noise pollution is expected to drive the growth of the glass wool acoustic insulation market in the future. Noise pollution refers to harmful or excessive unwanted sound levels that disrupt the natural balance and adversely impact human health and the environment. This rise in noise pollution is attributed to rapid urbanization, as expanding cities generate more traffic, construction, and industrial activities, which raise ambient noise levels. Glass wool acoustic insulation reduces noise pollution by absorbing sound vibrations and limiting the transmission of airborne noise, resulting in quieter and more comfortable indoor environments. For example, in June 2025, the European Environment Agency, based in Denmark, reported that over 150 million people, accounting for more than 30% of the EU population, are exposed to harmful long-term transport noise. Additionally, in 2023, the Brisbane Flight Path Community Alliance, an Australian community group, stated that over half of Brisbane’s population - approximately 1.39 million people - are affected by aircraft noise, with 26% moderately and 9% severely impacted. Thus, the growing noise pollution is propelling the expansion of the glass wool acoustic insulation market.

Leading companies in the glass wool acoustic insulation market are focusing on creating advanced solutions, such as glass mineral wool, to improve thermal and acoustic performance while enhancing sustainability through eco-friendly binders. Glass mineral wool is a fibrous insulation material made from melted recycled glass, designed for both thermal and acoustic insulation uses. For instance, in March 2025, Knauf Insulation, a German manufacturer, introduced its Earthwool Metal Roofing Roll range in Thailand. This product line is specifically designed to provide superior performance for roofing on profiled metal-clad structures. It includes faced and unfaced options to accommodate different installation needs. The faced version features a reflective foil to boost thermal efficiency, especially in hot climates. Overall, this launch signifies Knauf’s extension of high-quality glass mineral wool insulation solutions tailored to the Southeast Asian market.

In April 2023, Saint-Gobain Group, a French manufacturing company, acquired Twiga Fiberglass for $48 million. Through this acquisition, Saint-Gobain seeks to strengthen its position in India’s insulation market by incorporating UP Twiga’s glass wool manufacturing capabilities and broadening its range of energy-efficient and acoustic building solutions. Twiga Fiberglass Private Limited is an India-based manufacturer of glass wool acoustic insulation.

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.

Glass wool acoustic insulation is a fibrous material designed to absorb sound by reducing noise transmission, dampening sound vibrations, and minimizing echoes within a space. Its engineered structure effectively traps air, which hinders the movement of sound waves, resulting in a quieter and more acoustically balanced environment.

The primary types of glass wool acoustic insulation include fiberglass insulation, mineral wool insulation, cellulose insulation, and polyurethane foam insulation. Fiberglass insulation is a thermal and acoustic insulating material made from fine glass fibers, widely used to reduce both heat transfer and noise in buildings. It comes in various forms such as batts and rolls, loose fill, board insulation, and spray foam, with thicknesses categorized as thin (up to 25 mm), medium (26 mm-50 mm), and thick (above 50 mm). This insulation is utilized across residential, commercial, industrial, automotive, and aerospace applications by multiple end-user industries including construction, manufacturing, transportation, and healthcare.
