Cork Board Insulation

Cork Board Insulation is a high performance, natural, sustainable and vapour permeable insulation system for use internally and externally.

Cork insulation boards provide excellent thermal and acoustic performance. The use of 100% natural expanded cork insulation boards on a building ensures maximum thermal insulation and a significant acoustic protection. Cork insulation is made from the natural cork which is removed from the tree every 9 years without the tree being cut down or harmed.

Cork insulation boards provide a breathable insulating material, free from chemicals or synthetic resins which ensures a healthy environment inside our buildings.

Cork has a low thermal conductivity (From 0,036 to 0,040 W/m.K) and comes in a range of sizes from 20mm up to 300mm.

Cork Boards are available in a range of thicknesses and each board measures 500 mm x 1000 mm. Supplied in packs – the number of boards per pack differs depending on the thickness of board.

The adhesive mortar Isovit E-Cork, constituted by natural hydraulic lime and cork aggregates, ensures the perfect compatibility and correct fixing of the insulation cork panels. Completed with the Reabilita Cal AC 100% natural hydraulic lime mortar as an effective protection against weathering.

  • It is vital to ensure the boards are applied to a level background.
  • Apply Isovit E-Cork with a 5mm notched trowel to the back of the Cork Board and stick it to the levelled masonry.
  • Insulated masonry fixings are not required for the majority of internal applications but should be used for external application.
