What is Natural Clay Siding?
Natural clay siding refers to exterior wall coverings made from clay-based materials that are applied directly to the building's surface. Unlike synthetic or processed cladding options, natural clay siding retains its organic composition, offering a rustic, textured appearance that ages gracefully over time.
Composition and Characteristics
- Primarily composed of naturally occurring clay minerals mixed with water and sometimes organic additives.
- Often includes mineral pigments for color variations.
- Features excellent breathability, allowing moisture to escape, reducing issues like mold or rot.
- Has a porous surface that can regulate humidity and temperature inside the building.
Types of Natural Clay Siding
Natural clay siding comes in various forms, each suited to different architectural styles and functional needs:
1. Clay Plaster
- Applied as a thick coat over walls.
- Provides a textured, rustic look.
2. Clay Tiles
- Used as exterior cladding panels.
- Offers a more uniform, structured appearance.
3. Engineered Clay Panels
- Pre-fabricated panels made from clay composites.
- Easier and quicker to install compared to traditional methods.
4. Natural Clay Brick
- Fired clay bricks with natural mineral glazes.
- Classic, durable, and timeless.
