Why Choose Sustainable Home Exterior Materials?
The environmental benefits of opting for sustainable home exterior materials are numerous. These materials often boast lower embodied energy – the total energy required to extract, process, manufacture, and transport them. Furthermore, they may be sourced locally, reducing transportation emissions, and can be recycled or reused at the end of their lifespan. Finally, many contribute to improved indoor air quality by being free of volatile organic compounds (VOCs). Beyond environmental advantages, these materials can also increase your home’s value and appeal to environmentally conscious buyers.
Popular Sustainable Exterior Options
Wood: Reclaimed & Sustainably Harvested
Wood remains a popular choice for siding, decking, and other exterior features. However, not all wood is created equal. Reclaimed wood, sourced from old buildings or structures, gives new life to existing materials, preventing them from ending up in landfills. Sustainably harvested wood, certified by organizations like the Forest Stewardship Council (FSC), ensures that forests are managed responsibly, promoting biodiversity and preventing deforestation. Look for wood varieties like cedar, redwood, and cypress known for their natural resistance to decay and insects.
Bamboo: A Rapidly Renewable Resource
Bamboo is a fast-growing grass that regenerates quickly after harvesting, making it a highly renewable resource. It is incredibly strong and durable, making it suitable for siding, decking, and even roofing. Bamboo products are typically treated to enhance their resistance to moisture and insects. However, it’s important to verify the source and treatment processes to ensure genuine sustainability.
Fiber Cement Siding: Durable and Eco-Friendly
Fiber cement siding is composed of cement, sand, and cellulose fibers. It is known for its durability, resistance to pests, and fire resistance. While not inherently renewable, fiber cement can often be sourced with recycled content. Additionally, its long lifespan minimizes the need for frequent replacements, reducing overall environmental impact.
Emerging Sustainable Exterior Materials
Recycled Plastic Lumber: A Sustainable Alternative
Recycled plastic lumber is made from recycled plastic bottles and other plastic waste. It is extremely durable, waterproof, and resistant to rot and insects. While it may not have the same aesthetic appeal as natural wood for some, it offers a sustainable alternative that helps to divert plastic from landfills.
Living Walls: Bringing Greenery to Your Exterior
Living walls, also known as vertical gardens, are not traditional building materials, but they significantly contribute to a sustainable home exterior. They provide insulation, reduce stormwater runoff, and improve air quality. Living walls can be integrated into existing structures or designed as a key element of new construction.
Considerations When Choosing Sustainable Materials
Life Cycle Assessment
Conducting a life cycle assessment of different materials can help you make informed decisions. This involves analyzing the environmental impact of a material from its extraction to its disposal.
Local Sourcing
Choosing materials sourced locally reduces transportation emissions and supports the local economy.
Durability and Maintenance
Selecting durable materials that require minimal maintenance extends their lifespan and reduces the need for frequent replacements.
Cost
While some sustainable materials may have a higher upfront cost, their long-term benefits and reduced maintenance can often make them a more cost-effective choice in the long run.
Beyond Materials: Sustainable Building Practices
Choosing sustainable home exterior materials is just one piece of the puzzle. Sustainable building practices, such as energy-efficient design and water conservation measures, are equally important for creating a truly environmentally friendly home.
Conclusion
Choosing sustainable home exterior materials is a significant step towards creating an eco-friendly home. By considering the environmental impact of your choices, you can reduce your carbon footprint, conserve resources, and contribute to a healthier planet. From reclaimed wood to recycled plastic, the options are vast and ever-evolving. Research and explore the materials that best suit your needs and values, and embark on a journey towards a more sustainable future, one exterior at a time.
