Cork Insulation Boards
Cork insulation boards are rigid panels made from natural cork granules, harvested from the bark of cork oak trees. The material is processed using heat and pressure, allowing the cork to bind naturally without synthetic adhesives.
Cork is a renewable material that can be harvested without cutting down the tree, making it a highly sustainable insulation option.
Key Features of Cork Insulation Boards
1. Excellent Thermal Insulation
- Provides stable indoor temperatures by reducing heat transfer.
2. Natural Acoustic Performance
- Absorbs sound, improving noise control in buildings.
3. Moisture Resistance
- Resists water and helps prevent mold growth.
4. Breathable Material
- Allows vapor diffusion, reducing condensation issues.
Types of Cork Insulation Boards
1. Expanded Cork Boards
- Made using heat expansion process
- Darker color and fully natural bonding
2. Agglomerated Cork Boards
- Bound with natural or minimal adhesives
- More uniform structure
3. High-Density Cork Panels
- Stronger and more durable
- Suitable for floors and structural applications
Common Applications
- Walls: Interior and exterior insulation systems
- Roofs: Thermal and moisture control
- Floors: Insulation and soundproofing
- Facade Systems: Exterior building insulation
- Eco Homes: Sustainable construction projects
