12 Dec Sustainable Building Materials Homeowners Love for 2026

The sustainability trend is growing among Quad Cities homeowners in 2026. In fact, sustainable building materials have never been more popular throughout the country. And we know why. These high-performing materials are as earth-friendly as they are durable. From well-thought-out structural supplies to exterior design and even interior aesthetics, sustainable building materials are showing up at each stage of your home’s construction. 

Incorporating the natural aesthetic in your home for 2026 means you can choose from a variety of earth-friendly products without increasing your carbon footprint. Sustainable building materials like bamboo and engineered mass timber, along with hempcrete, are fast replacing steel and concrete in structures, not just for their eco-friendly nature but also for their durability. 

What are the top sustainable building materials homeowners love in 2026? Let’s take a look!

Sustainable Building Materials for Structural Use

Whether you’re remodeling, planning an addition, or renovating a structure, there are some wonderful ways to maintain sustainability and ensure your work is sound. Here are the top materials for structural use.

Engineered Wood

Builders refer to this product as mass timber when used in structural building. The manufacturer incorporates smaller pieces of wood, wood scraps, and wood fiber, and binds them with adhesives and mechanical fastening. This creates large, durable structural components such as columns, beams, panels, and posts. 

Because mass timber is manufactured off-site, your construction takes less time to complete. Another benefit of engineered wood? It’s fire-resistant and only chars on the outside, which means your structural integrity is sound and safe. And the manufacturing of your engineered wood results in lower greenhouse gas emissions when compared to the production of steel and concrete.

Bamboo

Bamboo is one of the most sustainable building materials around and has been used for decades in building as reinforcement for concrete, post-and-beam, and difficult space framing. 

Because of bamboo’s lightweight, flexible, and tensile nature, it’s an excellent material for challenging building projects. 

Hempcrete

This highly sustainable building material is made by combining the inner core of the hemp plant with a lime binder. The result is a lightweight, breathable, and durable material ideal for insulation and infill. Not only is hempcrete fire-resistant, but it also dissipates flames and does not emit toxins. Hempcrete is resistant to rodents and insects and is impervious to mold.

Cork

Another excellent and highly sustainable option for insulating your structure is cork. Professional builders prefer cork for its thermal as well as acoustic insulating properties. This versatile product has a natural cellular structure that traps air, improving your home’s overall energy efficiency. Cork is used in various ways to enhance structural integrity. This includes insulating walls, roofs, and floors, as well as exterior cladding due to cork’s effective waterproofing ability.

Sustainable, Recycled, and Salvaged Materials

Additional eco-friendly materials homeowners love for 2026 are those repurposed materials and recycled materials that would otherwise go to a landfill. What’s more sustainable than salvaging these products? 

• Recycled Steel: Steel can be recycled over and over and remain structurally strong. It can be used in prefab components such as walls and trusses, or to create rebar, beams, and columns, framing, and to reinforce concrete. 

• Recycled Wood: As mentioned, wood scraps and wood fiber go into the production of mass timber, engineered wood building materials. 

• Recycled Glass: Glass scraps are often repurposed as a way to strengthen concrete building materials. Glass improves the durability of load-bearing bricks and panels. Glass can be processed into insulation and cladding for fire resistance. 

While sustainability in building materials is a popular trend, you must use care when selecting the right material for the job. No matter how sustainable building materials may be, they are only as good as their strength and durability. Rest assured, the materials we’ve reviewed here are highly functional for building purposes and ensure the integrity of your project for decades to come.
