Market Drivers
Increasing Industrial Energy-Efficiency Requirements are Accelerating the Adoption of OEM Insulation Materials
OEM Insulation Materials Market is gaining momentum as industrial manufacturers are concentrating more on reducing thermal losses, improving equipment efficiency, maintaining process temperatures and reducing energy consumption. Insulation materials are being used in industrial machinery and process equipment, boilers, storage systems, HVAC equipment and other OEM-manufactured systems to reduce unwanted heat transfer and improve operating efficiency.
According to the IEA’s Global Energy Review 2025 said that industrial electricity consumption rose by almost 4% in 2024 and accounted for almost 40% of the total increase in global electricity demand in the year. As industrial processes are being increasingly electrified and equipment is subjected to higher thermal loads, OEMs will likely require more mineral wool, fiberglass, elastomeric foam, polyurethane foam and other insulation materials for thermal protection and energy conservation.
Expansion of HVAC, Appliance, and Transportation Manufacturing is Increasing OEM Insulation Consumption
Increased production and use of HVAC equipment, household appliances, automobiles, rail systems, and other transportation equipment is driving demand for thermal and acoustic insulation materials. OEM insulation is increasingly being used in air-conditioning systems, refrigerators, ovens, water heaters, automobiles, railcars and specialty equipment to reduce heat transfer, control noise and vibration, improve passenger comfort and enhance equipment energy efficiency.
According to the International Organization of Motor Vehicle Manufacturers (OICA) reported that, in 2025, Asia-Pacific produced around 59.2 million vehicles, up 7.6% from the previous year, accounting for more than 61% of global vehicle production. In 2025, China alone produced about 34.53 million vehicles, with new-energy vehicle production hitting 16.63 million units, up 29%.

Segmental Insights
Why is Mineral Wool Acquiring the Largest Share?
On the basis of material type, the mineral wool segment is projected to account for the largest OEM Insulation Materials Market share of approximately 38.0% in 2026. The segment’s growth is owing to its high-temperature resistance, non-combustibility, acoustic performance, dimensional stability, and suitability for industrial machinery, HVAC systems, transportation equipment, data centers, and other OEM applications.
Mineral wool also provides a significant technical advantage in high-temperature and fire-sensitive OEM environments. ROCKWOOL states that stone wool insulation can resist temperatures above 1,000°C and maintain its performance for at least 65 years, which enhances its appropriateness for use in situations where the need for thermal stability, fire safety and long operating life is high.
In May 2026, ROCKWOOL announced an agreement to acquire Ravago’s stone wool plant in Hungary, strengthening its mineral wool production footprint across Central and Eastern Europe. The facility can produce around 40,000 tons of stone wool annually and employs more than 100 people.
Why does the Industrial Segment Hold the Largest Market Share?
On the basis of end-use industry, the industrial segment is expected to lead with approximately 38.0% share in 2026. The segment’s growth is owing to the extensive use of insulation across process equipment, boilers, piping systems, storage vessels, industrial HVAC units, machinery, power-generation equipment, and other systems were reducing heat loss and maintaining operating temperatures directly improve energy efficiency and process performance.
The IEA reported that energy-intensive industries represent approximately three-quarters of total industrial energy demand, with many industrial processes requiring heat at temperatures above 500°C. Such high operating temperatures are supporting demand for mineral wool, fiberglass, cellular insulation and other high-performance materials that can reduce thermal losses and protect surrounding equipment.
In June 2025, Armacell launched a new aerogel insulation manufacturing plant in Pune, India, to manufacture its ArmaGel XGH and ArmaGel XGC insulation blankets for the global market. The new ArmaGel XG range is designed for demanding industrial and energy applications, covering operating temperatures from around -196°C (-321°F) to +650°C (+1,200°F).
Why is Blanket Insulation Acquiring the Largest Share?
On the basis of insulation type, the blanket insulation segment is projected to account for the largest share of approximately 39.0% in 2026. The segment’s growth is owing to its flexibility, relatively low weight, ease of cutting and fabrication, adaptability to curved and irregular equipment surfaces, and ability to provide both thermal and acoustic insulation across appliances, HVAC equipment, automotive systems, rail equipment, and other OEM applications.
Current OEM product specifications illustrate these advantages. Johns Manville’s SG Series Spin-Glas insulation is specifically designed as a lightweight blanket for transportation, appliance, HVAC, and specialty OEM applications.

Analyst Opinion
- The OEM Insulation Materials Market is gradually shifting from conventional commodity insulation toward engineered, application-specific thermal-management solutions, particularly in electric vehicles, energy equipment, and other space-constrained OEM systems. Aspen Aerogels reported USD 168.9 million in thermal-barrier revenue in 2025 and has multi-year production contracts with OEMs including General Motors, Toyota, Scania, ACC, Volvo, and Volvo Truck for its PyroThin aerogel thermal barriers.
- Sustainability credentials are becoming an increasingly important purchasing criterion alongside thermal and acoustic performance. Owens Corning reported in its 2025 Sustainability Report that its Thermafiber mineral wool insulation contains a weighted average of 70% recycled content, while its commercial and industrial fiberglass insulation averages 53% recycled content. Its North American FOAMULAR NGX extruded-polystyrene insulation also contains an average of 20% recycled content.
- Regulatory changes are likely to accelerate reformulation of foam-based OEM insulation and favor suppliers with low-global-warming-potential technologies. Under the U.S. EPA's Technology Transitions Program, beginning January 1, 2025, polyurethane foams, extruded-polystyrene foam, phenolic insulation foam, polyisocyanurate foam, and several other foam categories became subject to a GWP limit of 150 for specified blowing agents. The broader AIM Act framework targets an 85% phase-down in U.S. HFC production and consumption by 2036.
