A development that underscores stability in the growing segment of bio-based insulation materials: STEICO has published its final annual financial statements for 2025 and thereby confirms without corrections the previously communicated preliminary figures. The Bavarian manufacturer of wood fiber insulation benefits from the sustained demand for sustainable building materials, particularly in the context of tightened Building Energy Act (GEG) regulations and the growing relevance of Environmental Product Declarations (EPD) in tendering practices.
Wood fiber insulation materials typically achieve lambda values between 0.038 and 0.045 W/(m·K) and thus compete in the range of mineral wool and EPS. Their decisive advantage lies in CO₂ storage: Per cubic meter of STEICO insulation, between 150 and 200 kg of biogenic CO₂ are sequestered depending on the product line. This characteristic is gaining importance as planners increasingly must evaluate overall life cycle assessments according to DGNB criteria.
The confirmed balance sheet without post-corrections indicates a stable operational foundation, although the European insulation market in 2024/25 was characterized by overcapacity and price pressure. While competitors such as ISOVER and ROCKWOOL are discussing consolidation in the mineral wool segment, STEICO is strategically positioning itself in the premium segment for ecological refurbishment and timber construction. Particularly in the area of multi-story timber construction, demand is increasing for diffusion-open insulation systems with high bulk density (160–270 kg/m³) that can simultaneously serve as bracing elements in timber frame constructions.
For architects and planners, STEICO's stable market position provides important planning certainty: The availability of wood fiber insulation materials with general building authority approval for applications in fire protection class B-s1, d0 (according to DIN EN 13501-1) remains guaranteed. At the same time, the choice of material supports compliance with ESG requirements of institutional building owners who increasingly demand circular building concepts with recyclable, single-material components. The confirmation of the annual financial statements without revision signals that STEICO can serve this demand cost-effectively – an indicator of the competitiveness of bio-based insulation materials compared to conventional alternatives.
