Building insulation is a common practice, often using materials from petrochemicals or natural sources with high energy consumption. This paper aims to report the state of the art of building insulation products made of natural or recycled materials that are not or scarcely commercialized. Comparative analyses were conducted to evaluate the use of industrial, agricultural, C and D, and municipal solid wastes in producing innovative thermal and acoustic insulating building materials.
The paper provides a comprehensive review of the main commercialized insulation materials (conventional, alternative, and advanced) for the building sector through a holistic and multidisciplinary approach. The authors also discuss unconventional sustainable building insulation materials, such as clay blocks and rice balls, which have shown better thermal insulators than simple clay blocks. Sawdust composites are also attractive for their low thermal conductivity, high sound absorption, and good sound insulation characteristics.
Unconventional materials are frequently repurposed for use as eco-friendly insulation materials within the walls or roof of a building. The findings indicate that these new types of insulation materials can compete with conventional insulation materials and offer good thermal conductivity value. The energy efficiency and sustainability of buildings are evaluated based on factors such as thermal insulation thickness, heating demand, and primary energy sources.

What insulation is eco-friendly?
Green insulation options, such as sheep’s wool, cotton, aerogel, rigid polystyrene, and Icynene, are made from renewable resources and recycled materials, aiming to reduce energy costs and improve home insulation. Some options offer superior insulation qualities, while others like sheep’s wool and cotton provide natural and less toxic alternatives. Soybeans, found in milk, candy, disinfectants, insecticides, cooking oils, and margarine, can also be used in home insulation.
Chicago homeowners Jason and Jennifer LaFleur discovered that they could save money by using soybean foam insulation instead of conventional fiberglass insulation. Alternative insulation materials like shredded denim, hemp, and sheep’s wool can save homeowners money and contribute to the environment.
What kind of insulation is eco-friendly?
The best insulation options include cellulose made from recycled paper, sheep’s wool or hemp insulation for higher budgets, and cork for wetter climates. Cellulose insulation is cost-effective and high-performance, while sheep’s wool or hemp insulation offer excellent thermal properties and humidity regulation. The best choice balances environmental responsibility, comfort, and affordability, making it a versatile and cost-effective choice.
What is the most effective building insulation?
The five most efficient insulation materials are fibreglass, cellulose, mineral wool, and polystyrene. Fibreglass, also known as glass wool, is the most widely used insulating material. It is made by melting recycled glass, soda ash, and limestone together until molten. Once molten, the mixture can be spun into thin fibres, which can be woven into various shapes and thicknesses. Cellulose, made from recycled paper products, is an environmentally friendly insulator. Mineral wool is another option, and polystyrene is another efficient option. Using the right insulation materials can reduce energy bills by up to 50%.
What are the types of unconventional materials?
The art world employs a variety of unconventional materials, including neon lights, rice paper, steel pins, and even garbage. Some artists employ these materials to create distinctive works of art. For instance, Jacob Hashimoto utilizes wood, acrylic, bamboo, paper, and Dacron, Tara Donovan employs gatorboard, paint, and nickel-plated steel pins, and Jean-Michel Othoniel makes use of mirrored glass and stainless steel.
What does it mean sustainable insulation?
Sustainable insulation is a concept that uses environmentally-friendly materials and techniques to make buildings more energy-efficient, maintain desired room temperatures, and improve indoor air quality. It aims to minimize environmental impact while improving the overall efficiency of structures. Sustainable insulation is crucial for achieving energy-efficient and eco-friendly buildings, saving energy, enhancing indoor comfort, and encouraging sustainable living practices.
Traditional insulation methods like fiberglass, foam, and mineral wool have their drawbacks, but it’s high time for a sustainable upgrade to create healthier and more sustainable living spaces. By properly insulating homes and offices, we can save energy, enhance indoor comfort, and mitigate climate change.
What is the R-Value of denim insulation?
Denim insulation is an emerging house insulation material made from recycled denim jeans, suitable for walls, crawl spaces, ceilings, attics, and floors. It shares a similar R-Value of R-13 to R-19, indicating thermal resistance. The higher the R-value, the better the material’s thermal conductivity. Denim insulation is also a Class A fire-retardant, treated with borate flame retardants. It is easy to handle, acoustically efficient, and environmentally friendly.
Made from 100 recycled denim and treated with borate flame retardant, it is one of the most eco-friendly insulation options. Additionally, denim insulation can be recycled after use, extending its life.
What is an example of a sustainable building material?
Bamboo is a sustainable and versatile construction material due to its renewable nature and ability to absorb more CO2 than trees. It is cost-effective, eco-friendly, and can be used in various applications like concrete, scaffolding, and roofing. Bamboo’s growing demand could contribute to cleaner air. Additionally, the world’s population generated 139 million tons of single-use plastic in 2021, which was mostly disposed of in landfills or polluted waterways. Advancements in construction and technology can now recycle plastic into building materials like plastic sheets, bricks, and lumber.
Does denim make good insulation?
Denim insulation is an effective alternative due to its low density and resistance to thermal energy transfer. It traps heat in natural air gaps, reducing thermal bleed. Denim also provides better sound insulation, as its absorbent nature dampens sound better than any other insulator. This makes your space quiet and noise-free. Denim is also an environmentally friendly choice, as it is chemical-free and a recycled organic material. Its unique properties make it an excellent choice for homes, as it is a “green” choice, reducing the need for harsh chemical treatments and promoting a quieter, peaceful environment.

You have invented… A wooden house… Congratulations. So you make a biomaterial, meaning you have to deal with humidity, or your house can slowly be eaten up from the inside. It is also a bio material, so it is less resistant to bugs and bacteria. The Lego Design just makes it harder to build actual designs, so what is the point of that, beyond sounding smart and increasing cost? You need mortar anyway.
It’s a real shame that hemp, being such a useful and versatile material, seems inherently tied to cannabis. Of course, there should be no “destigmatisation” of the recreational consumption of cannabis, despite moves being made by some nations and states. However, this poses a serious problem when it comes to producing a reliable supply of usable hemp. We’ll probably have to bioengineer the hemp plant to produce a variety without intoxicating leaves before this catches on.
It sounds like a great idea. Unfortunately, the problem with bringing anything to market is not if it’s good but financing such as government subsidies and competition. Many great products never became successful because their rotten competition had more financing. Government subsidies / politics also can destroy not only a product idea but even nations.
Как дети, кому в этой системе нужны качественные, экологичные, экономичные,… материалы, наоборот нужны более дорогие, опасные, без никакого качества чтобы покупали, покупали, покупали и ничего путного не могли бы сделать как пример с пустой едой, желудок полный а пользы никакой, такое везде и во всем, вроде все есть а оно и нету ничего. Когда же люди поймут что решение всех проблем есть, только в этой системе это совсем не нужно, ей хорошо только когда есть беда, проблема, дефицыт, только на этом она и заточена а как находится решение так и сразу кризис.
my local sawmill offers throw away scrap that can be used for many purposes. I don’t have any codes, so I am in a bonus category. The privy, ok, though I’ve modified for that with solar compost to biomass burn. My experience with commercial lumber yards is not very good. I feel for those stuck on regulations based on bureaucracy.
I see your point, BUT its not negligible at all: You and your friend build your houses at the same time, the same standard (passive house minimum U=0,15 W/m²K). You build conventional (bricks, styrofoam), your friend builds from renewables (woodframe, strawbale insulated). When you get the key to your new house you already consumed so much fossile non renewable energy that your friends house can be heated for up to 70 years to reach that level. (plus CO2 storage, can be composted, widely available (local) materials etc)
Nice info, but my main complaint with stick built homes is that they are completely useless without being tied to the grid. I mean, if you don’t have gas, you don’t have hot water, so you can’t take a shower.. (or heat the place) You’re going to a hotel. You don’t have electricity, forget about it. And of course, if you don’t have water, good luck.
