Insulation

Cork & Hemp: Sustainable Insulation

  • Expanded Cork: Sourced from the bark of cork oak trees, expanded cork is renewable, biodegradable, and fire-resistant. It delivers superior thermal and acoustic insulation, making it an ideal long-lasting, eco-friendly choice.
     

  • Hemp Wool: Made from renewable hemp fibers, hemp wool regulates moisture to prevent mold and maintain indoor air quality. It provides excellent thermal and sound insulation, perfect for sustainable, healthy homes.
     

Each insulation option is carefully selected by Green Heritage to promote sustainable building practices, ensuring that our homes are comfortable, healthy, and have a minimal environmental impact.

Thermal Insulation

Expanded Corkboard offers exceptional thermal insulation with low conductivity and high inertia, maintaining stable indoor temperatures for sustainable, energy-efficient buildings.

​

Anti-Vibration Insultation

Expanded Corkboard is 98% resilient after compression, offering excellent anti-vibration insulation. It minimizes vibration spread, enhancing structure durability and comfort.

Acoustic Insultation

Expanded Corkboard effectively soundproofs by absorbing sound waves and reducing noise transmission. Perfect for enhancing interior acoustics and sound-controlled buildings.

Positive Impact on Cork Forests

Portugal’s 735,000-hectare cork oak forests provide significant environmental and social benefits. Cork oaks renewably produce cork every nine years, supporting sustainable construction and design.

 

These forests prevent soil desertification, sustain diverse European ecosystems, and capture around 5 million tons of CO₂ annually. Additionally, they create stable local employment and help prevent rural depopulation, making them essential for biodiversity and environmental health.

HEMP: Exceptional Insulation of Hemp Wool

Home construction in Portugal

Hemp Wool is a premium, sustainable insulation made from industrial hemp fiber. It provides excellent thermal, moisture-regulating, and acoustic properties, fostering a healthy and eco-friendly living environment. Ideal for roofs, façades, and floors in both new builds and renovations, hemp wool is a natural alternative to synthetic and mineral insulations. Its breathability and moisture control enhance durability and comfort, especially in vapor-permeable timber frame constructions.
