Mineral Wool Market Size & Share Analysis - Growth Trends And Forecast (2025 - 2030)

Global Mineral Wool Market Trends and Insights

Building And Construction Boom In Energy-Efficient Envelopes

Global decarbonization policies are steering retrofit budgets toward mineral-wool-based envelopes that pair air-sealing membranes with smart glazing. Regulation 2024/1681 in the EU obliges member states to renovate 3% of public buildings yearly, translating to a EUR 275 billion insulation opportunity this decade. India’s 2024 Energy Conservation Building Code overlays prescriptive U-values across 27 climate zones, while China’s DG/TJ08-205-2024 locks in 75% energy savings for new projects in Shanghai. Modular construction—scaling at 6.2% CAGR through 2024—now embeds mineral-wool cores into factory-built wall cassettes, trimming on-site labor by 40% and compressing installation schedules^{[1]Modular Building Institute, “2024 Modular Construction Report,” modular.org}.

Mandatory Energy-Performance And Fire-Safety Regulations

Litigation over combustible façades propels the mineral wool market as regulators outlaw polymer foams in tall buildings. The UK’s 2024 update to Approved Document B bans non-A-rated insulation above 18 m, a benchmark mirrored by Australia’s National Construction Code 2025 Performance Requirement FP1.4. EU Regulation 2024/3110 extends reaction-to-fire tests to sandwich panels, closing loopholes that once favored polyurethane cores. Parallel limits on VOCs in phenolic binders, as outlined in the Industrial Emissions Directive 2024/1785, reduce foam-production costs, narrowing the price gap with mineral wool^{[2]European Parliament, “Regulation 2024/1681 on the Energy Performance of Buildings,” europa.eu}.

Tightening Green-Building Codes In Emerging Asia-Pacific

Emerging Asia is leapfrogging legacy rules by embedding envelope thermal modeling into permit processes. India links floor-area-ratio bonuses to four-star GRIHA certification, mandating cavity insulation in most climate zones. Vietnam’s 2024 Circular 08/TT-BXD imposes energy audits for commercial buildings larger than 2,500 m², while Indonesia subsidizes mineral wool in 50,000 affordable homes. Guangzhou now requires thermal-performance reports that benchmark insulation thicknesses of 60–100 mm before project approval, signaling a shift toward performance-based design.

Circular-Economy Push For Mineral-Wool Recycling Streams

Europe produced 2.5 million tons of mineral-wool waste in 2020, yet recycling stood below 10%. Austria’s landfill ban from 2027 forces producers to build take-back loops, targeting a 30% recycling rate by 2030, which will add EUR 8–12 per m² for demolition contractors, as per BML.GV.AT. Rockwool and Knauf operate pilot plants in the Netherlands and Sweden that re-blend cleaned wool into virgin melts at a 15–20% ratio, reducing furnace energy consumption by 25%. New EU End-of-Waste criteria finalized in 2024 designate clean mineral wool as a secondary raw material, trimming cross-border shipping costs by 40%.

Health And Carcinogenicity Concerns Over Respirable Fibres

Ambiguity around bio-solubility fragments market access. EU Note Q exempts modern fibers from carcinogen labeling if the weighted half-life in lung fluid is under 40 days, yet OSHA still mandates hazard warnings on fibers below 3 µm. Insurance premiums for U.S. contractors rose 15–25% in 2024 due to liability concerns. 3M’s 2024 patent for ≥3 µm ceramic-glass fibres achieves 1,000°C performance while sidestepping respirable-dust generation, hinting at next-generation non-respirable products.

Price-Driven Substitution By Low-Cost Polymer Foams

Mineral wool trades at a 50–60% premium to EPS and a 20–30% premium to PIR because melting basalt or cullet at 1,400 °C is an energy-intensive process. Gas-linked input spikes in late 2023 lifted rock-wool list prices by 4.8–5.9% across Europe, while petrochemical foams enjoyed 12% cheaper feedstocks. In Southeast Asia, EPS controls 65% of low-rise insulation; mineral wool penetration is <15% beyond Singapore and Malaysia, where fire codes are stricter.

Segment Analysis

By Type: Glass Wool Growth Outpaces Stone Wool

Glass wool represented 62.52% of 2024 demand and continues to expand at a 7.06% CAGR, giving it the clear lead in the mineral wool market. The segment benefits from recycled-content mandates; Recticel integrated 19.2% post-consumer cullet in 2024 and targets 25% by 2030, reducing embodied carbon by 1.2 kg CO2-eq per kg of product. Stone wool, prized for its service temperatures exceeding 600 °C in industrial settings, grows more slowly at 5.8% because its density of 120–160 kg/m³ inflates logistics costs by 40% compared with glass wool batts. Slag wool remains inexpensive in Eastern Europe and parts of China due to the abundance of blast-furnace slag; however, as steel mills shift to electric-arc technology, this outlet is expected to shrink, restraining its 4.3% CAGR growth.

Second-order effects reinforce glass wool’s ascendancy. Owens Corning reported USD 1.02 billion in insulation revenue for Q3 2024, a 6% increase, driven by glass-wool shipments across the southern United States, where code-mandated R-30 walls have become the default. Conversely, Rockwool’s Asia-Pacific sales declined 5% as Chinese builders shifted to glass-wool blankets for easier retrofitting. Ultra-thin battery-pack mats, built on glass-ceramic composites patented by 3M, create fresh high-margin niches that stone wool cannot meet owing to density constraints.

By Product Type: Blankets Dominate Residential Retrofits

Blanket insulation controlled 67.79% of 2024 volume and is tracking a 6.47% CAGR to 2030, reinforcing its dominance in the mineral wool market. Retrofits in houses built before 1990 drive demand for blankets because compressible batts can be easily installed into irregular stud bays without the need for adhesives, reducing installation labor by 30–40%. Board products, with an 18.5% share, serve curtain-wall façades and sub-grade walls where a compressive strength of more than 40 kPa is mandatory. They log a 5.9% CAGR as rainscreen cladding becomes mainstream in commercial builds.

Loose-fill commands 10.3% share, supported by a 6.1% growth path lifted by US federal tax credits that reimburse 30% of attic-insulation spend up to USD 1,200 annually. Saint-Gobain’s Isover brand introduced a bio-based binder in 2024 that reduces formaldehyde emissions by 60%, alleviating concerns about indoor air quality in schools and hospitals. Smaller niches—including stitched mats and wired blankets for marine bulkheads—collectively hold 3.4% but command premium pricing due to weight and fire-resistance needs.

By End-User Industry: Buildings Lead, EVs Accelerate

Building and construction accounted for 59.89% of mineral wool in 2024 and is projected to rise by 6.42% annually to 2030, maintaining its position as the anchor customer. North American orders leapt 8% in Rockwool’s Q3 2024 books on the back of Inflation Reduction Act subsidies targeting envelope retrofits, yet Europe stayed flat as German permits fell 20% and France postponed EPBD enforcement to mid-2025. India’s green-materials market, meanwhile, is sprinting toward USD 38 billion next year, drawing seven domestic wool makers into the GRIHA catalogue.

Lithium-ion battery packs can reach temperatures of up to 800°C in thermal runaway events, and glass-ceramic mats outperform polymer foams in both temperature tolerance and non-combustibility. Industrial and consumer appliances are squeezed by aerogel blankets that achieve equal R-values at one-third the thickness. Marine, aerospace, and other niche sectors supply the remaining 5%, with composite-integrated solutions chipping away at conventional wool usage.
