Extruded Polystyrene Market Global Report 2026

The extruded polystyrene market size has grown strongly in recent years. It will grow from $6.46 billion in 2025 to $6.92 billion in 2026 at a compound annual growth rate (CAGR) of 7.1%. The growth during the historic period was driven by growth in residential construction, expansion of commercial building projects, increasing demand for energy-efficient insulation, rising investments in transportation infrastructure, and growth in cold chain storage facilities.

The extruded polystyrene market size is expected to see strong growth in the next few years. It will grow to $8.98 billion in 2030 at a compound annual growth rate (CAGR) of 6.7%. The growth during the forecast period can be attributed to increasing adoption of green building materials, rising investments in sustainable infrastructure, growing development of energy-efficient buildings, expansion of industrial construction activities, and increasing demand for advanced insulation solutions. Major trends during the forecast period include the increasing adoption of high-performance thermal insulation materials, growing demand for moisture-resistant insulation solutions, rising use of high-compressive-strength extruded polystyrene in infrastructure projects, expansion of extruded polystyrene applications in cold storage facilities, and increasing development of fire-retardant and durable insulation products.

The increasing construction activities are expected to drive the growth of the extruded polystyrene market going forward. Construction activities involve the development of residential, commercial, industrial, and infrastructure projects that require advanced insulation materials to improve energy efficiency and enhance structural performance. The growth in construction activities is driven by rapid urbanization and increasing demand for energy-efficient buildings. Extruded polystyrene contributes to the construction sector by offering excellent thermal insulation, moisture resistance, and long-term durability across various building applications. For instance, in February 2026, according to the Office for National Statistics (ONS), a UK-based government department, annual construction output in 2025 increased by 1.8% compared with the previous year. Therefore, the increasing construction activities are driving the growth of the extruded polystyrene market.

Major companies operating in the extruded polystyrene market are focusing on developing advanced thermoplastic insulation materials, such as extruded polystyrene (XPS) foam, to enhance building energy efficiency, minimize thermal bridging, and improve long-term structural durability. Extruded polystyrene (XPS) foam is a rigid, closed-cell thermoplastic insulation material manufactured through an extrusion process that provides high thermal resistance, moisture protection, and compressive strength for construction and industrial applications. For instance, in May 2026, Owens Corning, a US-based building materials company, launched PINK Pipe Gel FG as part of its FOAMULAR XPS Pipe Insulation System for ammonia refrigeration facilities and cold storage environments. The system combines FOAMULAR XPS insulation with protective jacketing and vapor-retarder technologies to enhance insulation performance, corrosion resistance, and operational reliability in industrial settings. Therefore, the adoption of continuous insulation systems is becoming a key trend in the extruded polystyrene market.

In October 2024, Austrotherm, an Austria-based insulation materials company, acquired Monosi for an undisclosed amount. Through this acquisition, Austrotherm aims to enhance its presence in the Southeast European insulation market and expand its extruded polystyrene (XPS) insulation production capabilities. Monosi is a Greece-based manufacturer of insulation materials, including extruded polystyrene products.

Major companies operating in the extruded polystyrene market are BASF SE, Compagnie de Saint-Gobain, Dow Inc., LG Chem Ltd., Kingspan Group plc, Owens Corning, Austrotherm GmbH, DuPont de Nemours Inc., Kaneka Corporation, Ravago Group, Knauf Insulation GmbH, Soprema SAS, Synthos S.A., Supreme Petrochem Limited, TechnoNICOL Corporation, Emirates Extruded Polystyrene L.L.C., Etex Group, Karl Bachl Kunststoffverarbeitung GmbH & Co.
