Hygroscopic Building Material Market Report 2025

The hygroscopic building material market size has grown strongly in recent years. It will grow from $8.59 billion in 2024 to $9.17 billion in 2025 at a compound annual growth rate (CAGR) of 6.8%. The growth during the historical period can be credited to the rising demand for sustainable construction materials, increased awareness of indoor air quality, greater adoption of passive building designs, enhanced use of natural insulation products, and heightened concerns about moisture-related damage in buildings.

The hygroscopic building material market size is expected to see strong growth in the next few years. It will grow to $11.76 billion in 2029 at a compound annual growth rate (CAGR) of 6.4%. The growth anticipated in the forecast period can be attributed to an increased emphasis on green building certifications, accelerating urbanization and housing needs, growing investments in energy-efficient infrastructure, broader adoption of eco-friendly construction materials, and rising demand for smart, adaptive building systems. Key trends during this forecast period include advancements in smart moisture-regulating materials, improved integration with HVAC systems for humidity control, the development of bio-based hygroscopic composites, innovations in energy-efficient building insulation, and the creation of multifunctional wall systems with humidity buffering capabilities.

The increasing adoption of green building practices is expected to drive the growth of the hygroscopic building material market going forward. Green building practices involve designing and constructing buildings that are safe for occupants, use less energy and water, and are environmentally friendly. This rise is fueled by the need to lower energy costs, helping individuals and businesses save on electricity and heating expenses over time. Hygroscopic building materials support these practices by naturally regulating indoor humidity, reducing dependence on mechanical ventilation and air conditioning, and enhancing energy efficiency while improving indoor air quality and occupant comfort. For example, in February 2024, the US Green Building Council, a US-based non-profit organization, reported a 9% increase in leadership in energy and environmental design (LEED) certifications in 2023 compared to the previous year, with 21 additional certifications granted to single-family homes. Moreover, the number of newly registered LEED projects surged by 51%, indicating significant growth. Thus, the growing adoption of green building practices is driving the expansion of the hygroscopic building material market.

Leading companies in the hygroscopic building material market are focusing on developing innovative solutions such as bio-sourced wood-fiber insulation panels to enhance indoor air quality and moisture regulation. These panels, made from renewable wood fibers, passively absorb and release indoor moisture, helping balance humidity while providing thermal and acoustic insulation. For instance, in February 2023, Isonat, a France-based building materials manufacturer, introduced the Flex Contact range - bio-sourced wood-fiber insulation panels. These flexible, eco-friendly insulation boards made from natural wood fibers offer excellent moisture regulation, breathability, and ease of installation. They improve indoor comfort by maintaining stable humidity, support green building certifications, and reduce energy consumption in heating and cooling systems.

In May 2024, Saint-Gobain, a France-based manufacturing and materials company, partnered with TimberHP to offer advanced insulation materials. Through this collaboration, Saint-Gobain sought to expand its footprint in the sustainable insulation market by distributing TimberHP’s natural wood-fiber insulation products across North America, promoting environmentally friendly building solutions that enhance energy efficiency, indoor comfort, and the wider use of natural hygroscopic materials in green construction. TimberHP is a US-based building materials manufacturer specializing in eco-friendly wood-fiber insulation products for buildings.

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.

The rapid escalation of U.S. tariffs and the resulting trade tensions in spring 2025 are significantly impacting the construction sector, particularly in materials procurement and project costs. Higher duties on imported steel, aluminum, lumber, and machinery have driven up expenses for builders, contractors, and infrastructure developers, leading to increased project bids and delayed timelines. Construction equipment manufacturers face similar challenges, with tariffs on essential components and raw materials inflating production costs and squeezing margins. Additionally, retaliatory tariffs in international markets have curtailed exports of U.S.-made construction equipment and materials, further affecting profitability. The sector must now prioritize local sourcing, modular construction techniques, and supply chain diversification to control costs and ensure project viability amid ongoing trade uncertainties.

A hygroscopic building material is one that can absorb and release moisture from the surrounding air. These materials naturally help regulate indoor humidity by absorbing moisture when the air is humid and releasing it when the air is dry. This characteristic enhances indoor air quality and comfort while reducing the chances of condensation, mold growth, and material deterioration.

The main types of hygroscopic building materials are natural and synthetic. Natural hygroscopic materials, such as wood, wool, clay, and hemp, inherently absorb and release moisture from the air, aiding in indoor humidity regulation. Their primary functions include moisture control, temperature regulation, and sound insulation. They come in various forms, including solid materials, foam-based materials, and composite materials. These materials find applications across residential, commercial, and industrial buildings, with primary uses in construction, renovation, and restoration projects.
