Roof Insulation Market Report 2026

The roof insulation market size has grown steadily in recent years. It will grow from $10.89 billion in 2025 to $11.41 billion in 2026 at a compound annual growth rate (CAGR) of 4.8%. The growth in the historic period can be attributed to growing need for energy-efficient roofing systems, reliance on traditional insulation materials, expansion of residential construction activities, stable availability of mineral wool feedstock, historical use of fiberglass batts in roof applications.

The roof insulation market size is expected to see steady growth in the next few years. It will grow to $13.68 billion in 2030 at a compound annual growth rate (CAGR) of 4.6%. The growth in the forecast period can be attributed to rising adoption of high-performance insulation solutions, increasing regulatory pressure for building energy efficiency, shift toward sustainable and recycled insulation materials, growth in retrofitting of existing buildings, expanding use of advanced reflective and foam-based insulation technologies. Major trends in the forecast period include increasing demand for high-efficiency roof insulation materials, rising adoption of fire-resistant roof insulation solutions, growth in retrofit and roof energy-efficiency upgrades, expansion of lightweight and durable insulation products, increasing use of recycled and bio-based insulation materials.

The rising number of residential constructions is anticipated to drive the growth of the roof insulation market in the coming years. Residential construction includes the development of new spaces or the renovation of existing ones, such as buildings, apartments, and housing units intended for personal occupancy. Roof insulation is essential for enhancing energy efficiency, lowering energy costs, and providing additional protection for buildings. For example, in June 2024, the United States Census Bureau, a US government agency, reported that privately owned housing completions reached a seasonally adjusted annual rate of 1,514,000, marking a 1% increase from 1,499,000 in May 2023. Thus, the growing number of residential constructions is fueling the demand for roof insulation.

Leading companies in the roof insulation market are concentrating on developing advanced products, such as thermal and acoustical fiberglass insulation, to comply with increasingly stringent sustainability standards in construction. Thermal and acoustical fiberglass insulation consists of fine glass fibers that reduce heat transfer and absorb sound, enhancing energy efficiency and noise control across residential, commercial, and industrial buildings. For example, in September 2024, Knauf Insulation Inc., a US-based building insulation manufacturer, introduced its Performance+ residential portfolio of thermal and acoustical fiberglass insulation. The portfolio includes Performance+ EcoBatt, EcoRoll, Jet Stream Ultra Blowing Wool, and EcoFill Blowing Wool. These products are formaldehyde-free, low in dust and VOCs, certified as Asthma & Allergy Friendly and Verified Healthier Air, and specifically designed for residential applications such as walls, attics, and ceilings, delivering both energy efficiency and improved indoor air quality.

In March 2023, Installed Building Products Inc., a US-based construction company specializing in existing home insulation, after-paint products, residential, and commercial insulation construction, acquired Anchor Insulation Co. Inc. for an undisclosed amount. This acquisition allowed Installed Building Products to extend its reach for residential, commercial, and industrial customers throughout the Northeastern United States. Anchor Insulation Co. Inc., based in the US, is engaged in the installation of mechanical, residential, and industrial insulation.

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 influencing the roof insulation market by increasing costs of key raw materials such as glass wool, plastic foam chemicals, mineral fibers, and reflective insulation components, leading to cost escalation and supply delays across residential and non-residential roofing projects. Markets with high dependence on imported polymers and fiberglassparticularly Asia-Pacific and Europeare most affected. However, tariffs also encourage domestic material sourcing, strengthen local manufacturing capacity, and promote innovation in affordable high-performance insulation technologies.

Roof insulation is the thermal insulation present in a roofing system, typically provided by board-type products made from mineral fibers, cellular glass, foamed plastic, lightweight concrete, wood fiberboard, or other materials. These products may have different substances on the front or back, contributing to effective thermal insulation.

The primary types of roof insulation include batts and rolls, rigid insulation, and reflective systems. Batts and rolls, made of materials such as glass wool, stone wool, and plastic foam, are inserted into cavities between wood frames to control temperatures. They are utilized in both residential and non-residential buildings for flat and pitched roofs.Asia-Pacific was the largest region in the roof insulation market in 2025.
