Thermal Insulation Products Market in 2025: High-performance and sustainable solutions adapted to new regulatory requirements

According to the research firm MSI Reports, demand is refocusing around high-performance, sustainable solutions adapted to new regulatory requirements, confirming the strategic role of insulation in construction and especially renovation projects.

A new MSI Reports study analyzes the market for thermal insulation products for buildings in France, from 2019 to 2025 and up to 2030 (forecast).

According to MSI Reports, 2025 marks a return to a more stable pace after several turbulent years. Energy-efficient renovations remain the primary market driver, supported by ongoing incentive programs and improved economic visibility. Stabilized inflation and gradually improving financing conditions are facilitating the implementation of projects in both the residential and non-residential sectors, with a growing focus on overall building performance.

In the residential sector, energy-efficient renovations continue to shape demand. According to the research firm MSI Reports, insulation work on walls, roofs, attics, and floors remains a priority, driven by regulatory requirements and the gradual ban on renting out the most energy-inefficient properties. At the same time, the new residential market is showing signs of stabilization, with a renewed interest in energy-efficient homes that comply with the RE 2020 standard and anticipate future regulations.

The market in 2025 is characterized by strong material segmentation. Mineral wools retain a central position due to their thermal and acoustic performance and economic competitiveness, while cellular plastics, particularly EPS and PU, remain essential in certain key applications such as external thermal insulation, flooring, and roof terraces. According to MSI Reports, demand is also growing for specific technical solutions—thermo-reflective insulation, high-performance foams, and niche insulation—capable of meeting constraints related to space, fire safety, or durability.

Bio-based insulation materials are gaining increasing prominence in decision-making processes. According to MSI Reports, despite a mixed year in 2025, these materials are benefiting from favorable underlying trends: environmental regulations, the pursuit of a low carbon footprint, product innovations, and the rise of CSR initiatives. Their performance in summer comfort, the diversity of formats, and the industrial investments made are strengthening their credibility with specifiers and project owners.

In the medium term, the outlook for the building thermal insulation market remains geared towards moderate but sustainable growth. According to the research firm MSI Reports, the continued trend towards energy-efficient renovations, the progressive tightening of regulations (RE 2025, RE 2028, RE 2031), and evolving expectations from individuals and communities should continue to support demand. In this context, companies able to offer high-performance, integrated, and responsible solutions will have strong leverage to gain market share and support the transformation of the building stock.
