A Look at Popular Types of Eco Friendly Exterior Finishes
The market for sustainable building materials is growing rapidly, offering a diverse palette of Eco Friendly Exterior Finishes for various applications. Exploring these options helps homeowners and builders make informed choices that align with their budget, aesthetic preferences, and sustainability goals. Each type offers unique characteristics and benefits.
Sustainable Paints and Stains
Paint is a common exterior finish, and significant advancements have been made to make it greener. The primary focus is on reducing or eliminating VOCs and using more sustainable ingredients.
Low-VOC and Zero-VOC Paints
VOCs are solvents released as paint dries, contributing to smog and indoor air pollution. Low-VOC paints contain minimal levels (typically less than 50 g/L), while zero-VOC paints contain negligible amounts (often less than 5 g/L). Choosing these significantly improves air quality during application and afterward. Look for third-party certifications like Green Seal or UL GREENGUARD to ensure products meet strict standards.
Natural and Mineral Paints
These paints utilize natural, renewable resources like plant oils, resins, milk protein (casein), clay, and mineral pigments. They are inherently low or zero-VOC and often allow walls to “breathe,” which can be beneficial for moisture management in certain climates and building types. While they may require different surface preparation and application techniques than conventional paints, they offer beautiful, unique finishes and are fully biodegradable. Examples include:
- Milk Paint: Made from milk protein, lime, clay, and natural pigments. Durable and zero-VOC.
- Clay Paint: Uses clay as a binder, offering unique earthy textures and excellent breathability.
- Mineral Paints (Silicate Paints): Chemically bond with mineral substrates like stucco and concrete, creating a very durable, breathable, and long-lasting finish.
Natural Plasters and Renders
Traditional plasters and renders using lime or clay are inherently more sustainable than modern cement-based options. Cement production is a significant source of CO2 emissions.
Lime Renders
Lime render is a traditional building material made from lime, sand, and water. It is highly breathable, allowing moisture to escape walls, which is crucial for the health of older buildings and essential in damp climates. Lime absorbs CO2 from the atmosphere as it cures (carbonation), partially offsetting emissions from its production. It offers a durable, flexible, and naturally beautiful finish.
Clay Renders
Made primarily from clay, sand, and straw or other fibers, clay renders are one of the oldest and most sustainable finishes available. They have very low embodied energy, are non-toxic, and are fully biodegradable. Clay renders are excellent at regulating humidity and can create beautiful, textured surfaces, though they typically require protection from heavy rain or a breathable, water-resistant topcoat in exposed locations.
Recycled and Reclaimed Siding Materials
Giving new life to existing materials is a cornerstone of sustainable building. Recycled and reclaimed options reduce demand for virgin resources and keep waste out of landfills.
Recycled Plastic and Composite Siding
Siding made from recycled plastics (like milk jugs or plastic bags) or composites incorporating recycled content (wood fiber and plastic) offers excellent durability, weather resistance, and low maintenance. These materials divert vast amounts of plastic waste from landfills and oceans, though it’s essential to research manufacturers to ensure they use a high percentage of post-consumer recycled content and have responsible manufacturing processes.
Reclaimed Wood Siding
Using wood salvaged from old barns, factories, or homes offers a unique aesthetic filled with character and history. Reclaimed wood has virtually zero embodied energy from a fresh source and avoids the environmental impact of logging and milling new timber. It’s incredibly durable due to the age of the wood and can be milled into various siding profiles. Sourcing from reputable dealers ensures the wood is properly de-nailed, treated (if necessary, though often not needed for vintage wood), and ready for installation.
Bamboo Siding
Bamboo is a rapidly renewable grass that grows much faster than timber trees. Engineered bamboo products, including siding, can be very durable and stable when properly processed. Look for bamboo certified by the Forest Stewardship Council (FSC) or similar organizations to ensure sustainable harvesting and ethical labor practices.
Other Innovative Finishes
The world of Eco Friendly Exterior Finishes also includes other materials like:
- Fiber Cement Siding with High Recycled Content: Some manufacturers now incorporate significant amounts of recycled fly ash (a byproduct of coal combustion) or other industrial waste into their fiber cement products, reducing the need for virgin cement.
- Sustainable Stone and Brick: Sourcing local stone or using salvaged bricks minimizes transportation impacts. Permeable pavers for walkways near the house can also help manage stormwater.
- Green Walls and Vertical Gardens: While technically part of the landscape, a living wall as an exterior finish provides insulation, improves air quality, manages stormwater, and creates habitat. It’s a highly visible and impactful eco-friendly feature.
