Natural insulation materials refer to materials that are derived from nature, renewable or have low environmental impact, and are used in construction or industry to reduce heat transfer and improve energy efficiency. These materials usually include cellulose (from recycled paper or wood), wool, cotton, cork, straw, hemp fiber, coconut shell fiber and bamboo fiber, etc., and are favored for their sustainability and low carbon footprint. They achieve thermal insulation by reducing heat conduction, heat convection or radiation. The thermal conductivity (λ value) is usually between 0.03-0.07 W/m·K, which is comparable to traditional mineral wool or polystyrene (EPS), but has higher environmental value. It is widely used in the insulation of walls, roofs, floors and pipes.
The advantages of natural insulation materials are their eco-friendliness and health safety. Take cellulose as an example. It is made of 80%-90% recycled paper. After being treated with boric acid or borax, it has flame retardant and mildew-proof properties. The thermal conductivity is about 0.035-0.040 W/m·K. It can be blown in or sprayed, and is suitable for filling irregular spaces. Wool insulation uses the natural curling structure of sheep wool to capture air and form an insulation layer. It has a thermal conductivity of about 0.038 W/m·K and good hygroscopicity (it can absorb 30% of water without affecting performance). It regulates indoor humidity and is suitable for residential use. In addition, cork is used in the form of expansion molding or particle board, with a thermal conductivity of about 0.040-0.050 W/m·K. It is not only heat-insulating, but also sound-insulating and pressure-resistant. It is often used for floor and wall decoration.
From a performance perspective, natural insulation materials also have good air permeability and heat capacity. Air permeability allows water vapor to pass through, reducing the risk of condensation and mold. For example, the air permeability of hemp fiberboard in a high humidity environment is 50% higher than that of glass fiber, extending the life of the building. In terms of heat capacity, materials such as straw board (specific heat capacity of about 2000 J/kg·K) can store heat and slow down indoor temperature fluctuations, which is particularly suitable for passive building design. In addition, many natural materials can be naturally degraded or recycled. For example, cork and cellulose can be composted after their service life, while wool can be reused, which is in line with the concept of circular economy and significantly reduces the carbon footprint of the construction industry.
However, natural insulation materials also have some limitations. Their initial cost may be higher than synthetic materials. For example, the price of wool insulation board is 20%-40% higher than that of polystyrene because its production involves manual screening and washing. In addition, some materials are sensitive to moisture and pests. For example, untreated straw may attract rodents, requiring the addition of insect repellent or improved packaging technology. Installation complexity is also a challenge. For example, cellulose blowing construction requires professional equipment, while cork board cutting and splicing requirements are high, increasing construction time. At the same time, although flame retardant treatment has been widely used, natural materials may still not be as fire resistant as mineral wool (melting point>1000°C) in extreme fires, and need to be used in combination with fire protection design.
From the development trend, natural insulation materials are being driven by the demand for green buildings and zero-energy buildings (ZEB). New composite materials (such as cellulose mixed with hemp fibers) improve strength and insulation while reducing production energy consumption. In terms of sustainability, bamboo fiber has become an emerging choice due to its rapid growth (it can be harvested every year) and high strength (tensile strength of about 500 MPa). Its thermal conductivity is about 0.045 W/m·K, which is suitable for construction in tropical areas. Policy support is also accelerating its popularity. For example, the EU's Green Building Directive encourages the use of low-carbon materials, prompting manufacturers to develop more efficient natural insulation products. In the future, with the advancement of bio-based flame retardants and automated construction technology, natural insulation materials will play a greater role in energy-saving buildings and environmentally friendly designs, providing important support for achieving carbon neutrality goals.
