EXPANDED INSULATION CORKBOARD

Solution with high performance in thermal, acoustic and anti-vibration insulation, especially suitable for use in external, internal and cavity walls; slabs; flat and pitched roofs and radiant floor.


Datasheet






ROOFS

Applications

Expanded cork insulation is suitable for pitched and flat roofs, including:

  • Corrugated and membrane roof systems
  • Between-rafter and above-rafter insulation
  • Loose-fill insulation between joists
  • Green roofs and tapered roofs
  • Rigid insulation over slabs

It provides durable thermal and acoustic performance in new build and retrofit projects.

EXTERNAL WALLS

Applications

Expanded cork can be used in vapour-open external wall systems, such as:

  • ETICS / EIFS
  • Cavity walls with partial insulation
  • Ventilated façades
  • External cladding with exposed cork finish
  • Cladding over insulation or timber substrates
  • Internal insulation for external walls

These systems improve thermal comfort while supporting moisture-safe wall build-ups.

INTERNAL PARTITIONS

Applications

Cork insulation enhances internal wall performance in:

  • Stud and masonry partition systems
  • Double walls with full cavity insulation
  • Acoustic and thermal separation between spaces
  • Discontinuities between walls and slabs

It helps reduce sound transmission and vibration indoors.

INTERIOR DECORATIVE

Applications

Cork can be used as a visible interior finish for:

  • Decorative wall panels
  • Textured cork surfaces
  • Acoustic wall and ceiling solutions

These applications combine natural appearance with acoustic comfort.

SLABS AND FLOORS

Applications

Expanded cork is suitable for floor assemblies including:

  • Floating floors with wood or mosaic finishes
  • Impact sound reduction layers
  • Floor joist cavity insulation
  • Underfloor heating systems
  • Decorative and resilient floor solutions

It improves comfort, acoustics, and durability.

CEILINGS + OTHER APPLICATIONS

Applications

Expanded cork can also be used for:

  • Acoustic ceilings
  • Expansion joints and decoupling layers
  • Pipe and door core insulation
  • HVAC and machinery vibration control

Its elasticity and durability make it suitable for technical applications.
