Spray Foam Insulation Market Report 2026

The spray foam insulation market size has grown strongly in recent years. It will grow from $2.43 billion in 2025 to $2.59 billion in 2026 at a compound annual growth rate (CAGR) of 6.4%. The growth in the historic period can be attributed to growth of energy-efficient building practices, rising need for air-sealing solutions, early adoption of polyurethane insulation, expansion of residential and commercial construction, increased awareness of thermal performance requirements.

The spray foam insulation market size is expected to see strong growth in the next few years. It will grow to $3.32 billion in 2030 at a compound annual growth rate (CAGR) of 6.4%. The growth in the forecast period can be attributed to increased adoption of sustainable foam materials, expansion of automated insulation systems, rising demand for high-performance building envelopes, growth in green building regulations, increased investment in domestic chemical production. Major trends in the forecast period include increased adoption of eco-friendly insulation systems, growth in automated foam application technologies, rise in AI-based quality control, expansion of IOT-enabled temperature monitoring, shift toward sustainable formulations in foam production.

The growth of the spray foam insulation market is expected to be driven by the rise in construction activities. Construction refers to the process of building or assembling infrastructure such as buildings, roads, and bridges, and involves planning, designing, and executing these projects. The surge in construction activities is being propelled by rapid urbanization, which increases the need for housing and infrastructure, along with government initiatives that invest in large-scale infrastructure projects to stimulate economic growth. Spray foam insulation enhances energy efficiency in buildings by providing effective thermal insulation and air sealing, leading to reduced energy costs and improved indoor air quality by preventing drafts and moisture infiltration. For instance, in May 2024, the UK-based Office for National Statistics reported that in Quarter 1 2024, new construction orders rose by 15.9%, an increase of £1.43 billion ($1,920 million) compared to Quarter 4 2023. As a result, rising construction activities are boosting the spray foam insulation market.

Key players in the spray foam insulation market are focusing on developing innovative products, such as spray polyurethane foam insulation, to improve energy efficiency and sustainability in construction. Spray polyurethane foam insulation is a lightweight, rigid foam created by mixing polyol resin and isocyanate, which expands upon application to offer superior thermal resistance, air sealing, and moisture protection in various building applications. For example, in June 2024, Huntsman Building Solutions (HBS), a US-based manufacturer of polyurethane spray foam products, introduced Icynene Xpress 55, a new open-cell spray polyurethane foam insulation for unventilated attics and crawl spaces. This low-density product provides excellent thermal performance, with an R-value of R-3.7 at 1 inch and R-13 at 3.5 inches, along with strong adhesion to different substrates and noise reduction. Icynene Xpress 55 also meets strict fire safety standards set by the International Building Code and complies with AC-377 Appendix X, eliminating the need for an ignition barrier in utility-only attics.

In May 2024, Spray Foam Holdings LLC, a US-based manufacturer and distributor of spray polyurethane foam (SPF) products, acquired Thermoseal USA for an undisclosed amount. With this acquisition, Spray Foam Holdings aims to revitalize the Thermoseal brand by enhancing its research and development and manufacturing capabilities, making it more competitive in the insulation market with cutting-edge, energy-efficient spray foam insulation products. Thermoseal USA is a US-based manufacturer and distributor of eco-friendly spray foam insulation for commercial and residential buildings.

Major companies operating in the spray foam insulation market are BASF SE, Dow Inc., Honeywell International Inc., 3M Company, Covestro AG, DuPont de Nemours Inc., Sika AG, Owens Corning, Kingspan Group plc, Huntsman Corporation, RPM International, Sealed Air Corporation, CertainTeed, Tremco Incorporated, ArmorThane, Assured Insulation Solutions, Everchem Specialty Chemicals, FOAMETIX, Green Insulation, Lapolla Industries, Pacific Avenue Capital Partners LLC, Shakun Industries, Weatherization Services Inc.

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.

Tariffs are affecting the spray foam insulation market by increasing costs for imported isocyanates, polyols, blowing agents, and foam application machinery. Construction and automotive segments relying on foreign chemical inputs face higher material and installation costs, with the strongest impact in regions with heavy import dependence. Tariffs are driving growth in domestic chemical production and encouraging regional supply chains for insulation components.

This spray foam insulation market research report delivers a complete perspective of everything you need, with an in-depth analysis of the current and future scenario of the industry.

Spray foam insulation is a type of insulating material that is applied as a liquid and expands into a thick foam, forming an airtight seal. It is widely used in buildings to enhance energy efficiency by providing thermal insulation, minimizing air leaks, and serving as a barrier against moisture and sound.

The primary types of foams in spray foam insulation are closed-cell and open-cell. Closed-cell foam consists of tightly packed, unbroken cells, making it denser and more rigid. It is available in various densities, including high, medium, and low, and is used for applications such as wall insulation, attic insulation, roof insulation, and concrete rehabilitation. These foams cater to a variety of end-user industries, including packaging, construction, automotive and transportation, electrical and electronics, consumer goods, medical, and more.North America was the largest region in the spray foam insulation market in 2025.
