MD Fasada Expanded Cork

Next-Generation Natural Facade Insulation

MD Fasada Expanded Cork is a high-quality insulation board designed for external thermal insulation systems (ETICS). It is manufactured exclusively from natural cork granules, without the addition of polyurethane, synthetic adhesives, or any other chemical substances. By utilizing natural suberin as a binder, the result is a 100% ecological, durable, and health-safe insulation material.

The cork expansion process involves exposing cork granules to high temperature and steam. The granules increase in volume, while the naturally released suberin permanently bonds them together, creating a lightweight yet durable structure with exceptional insulating properties.

Why Choose MD Fasada?

MD Fasada combines excellent thermal insulation performance with high resistance to weather conditions and outstanding acoustic properties. It is particularly valued in energy-efficient, passive, and sustainable construction projects.

Key Benefits

  • 100% natural insulation material
  • No artificial binders or polyurethane
  • Excellent thermal and acoustic insulation
  • High resistance to moisture and ageing
  • Natural regulation of wall moisture
  • Vibration-dampening properties
  • Negative carbon footprint (CO₂)
  • Service life measured in decades
  • Fully recyclable

Technical Performance

MD Fasada offers outstanding performance characteristics:

  • Thermal conductivity coefficient: λ = 0.043 W/mK
  • Density: approximately 140 kg/m³
  • Compressive strength (at 10% deformation): 69 ± 27 kPa
  • Tensile strength perpendicular to the surface: 67 kPa
  • Fire reaction classification: Euroclass E
  • Dimensional stability verified according to European standards
  • High water vapour permeability, allowing building envelopes to “breathe”

Year-Round Comfort

The natural cellular structure of cork effectively reduces heat loss during winter while protecting buildings from overheating in summer. Thanks to its thermal energy storage capacity, walls maintain a stable temperature, resulting in lower heating and cooling costs.

Applications

MD Fasada cork boards are suitable for:

  • Thermal insulation of residential building facades
  • Energy-efficient and passive buildings
  • Historic buildings requiring natural construction materials
  • Sustainable and ecological construction projects
  • Thermal and acoustic insulation of external walls

Ecology and Healthy Indoor Climate

Expanded cork is one of the most environmentally friendly insulation materials available on the market. It is produced from the renewable bark of cork oak trees without the need to cut down the trees. Thanks to its natural properties, it helps maintain a healthy indoor climate and does not emit harmful substances.

By choosing MD Fasada, you invest in a durable, natural, and energy-efficient insulation solution that will effectively protect your building for many years to come.
