High Temperature Insulation Market Report 2026

The high temperature insulation market size has grown strongly in recent years. It will grow from $6.91 billion in 2025 to $7.44 billion in 2026 at a compound annual growth rate (CAGR) of 7.6%. The growth in the historic period can be attributed to expansion of heavy industrial manufacturing, growth of steel and cement production, rising energy costs in industrial processes, increased use of refractory materials, expansion of petrochemical infrastructure.

The high temperature insulation market size is expected to see strong growth in the next few years. It will grow to $9.75 billion in 2030 at a compound annual growth rate (CAGR) of 7%. The growth in the forecast period can be attributed to increasing investments in energy efficiency upgrades, rising adoption of high-temperature insulation in electric furnaces, expansion of industrial decarbonization initiatives, growing focus on lightweight insulation solutions, increasing demand from renewable energy facilities. Major trends in the forecast period include increasing use of ceramic fiber insulation, rising demand for energy-efficient thermal management, growing adoption in high-temperature industrial furnaces, expansion of lightweight insulating materials, enhanced focus on heat loss reduction.

The increasing use of petrochemical products is expected to drive the growth of the high-temperature insulation market going forward. Petrochemicals are chemicals derived from crude oil or natural gas and are used for a broad range of commercial applications. High-temperature insulation is essential in the petrochemical industry because it prevents heat transfer, protects materials and components near heat sources, and reduces the energy required to achieve optimal processing temperatures. For example, in October 2023, according to the U.S. Energy Information Administration, a US-based statistical agency, U.S. petroleum product exports reached nearly 6 million barrels per day (b/d) in the first half of 2023, marking a 2% increase compared with the same period in 2022. Therefore, the rising use of petrochemical products is fueling the growth of the high-temperature insulation market.

Major companies in the High Temperature Insulation Market are focusing on innovative technologies like rapid curing to increase production efficiency, enhance thermal performance, and lower costs. This is driven by the rising demand for high-performance insulation solutions in industries such as aerospace, automotive, and energy. Rapid curing accelerates the hardening or drying process, often through heat or chemical additives, leading to faster strength development. For example, in August 2024, PPG Industries, Inc., a US-based paint and coatings manufacturer, launched PPG PITT-THERM 909, a silicone-based formulation designed to prevent moisture accumulation, thereby reducing the risk of corrosion under insulation (CUI) and extending the lifespan of assets.

In March 2023, Etex, a Belgian-based manufacturer specializing in gypsum products, successfully completed the acquisition of Skamol, a Danish company renowned for its specialty high-temperature insulation systems. The financial details of the transaction remain undisclosed. This strategic acquisition aligns with Etex's existing product offerings, especially in the realm of calcium silicate boards, where Etex has a significant presence through its Promat business. Skamol, recognized for its expertise, manufactures insulation systems designed for various applications, including industrial kilns and furnaces, domestic stoves and fireplaces, mold prevention in homes, and fire protection solutions.
