Features and applications

  • Traditerm Nature external thermal insulation system (EWI/ETICS).
  • 100% natural insulation.
  • Thermal insulation.
  • Acoustic insulation.
  • Highly breathable.
  • Light and workable material.
  • Easy to cut.
  • Range of thicknesses that provide different levels of insulation.

Instructions for use

  • The panels are fixed to the substrate with Traditerm mortar adhesive, previously applied with a notched trowel. 
  • The panels are installed in an offset position (25 cm minimum interlocking between the vertical joints of the panels).
  • In the event of not being able to smooth unevenness between panels by sanding, it is essential to control the surface flatness when applying the finishing coat. 
  • Position fixings in the panels, 8 units per m2. The upper part of the fixing should be inserted some mm inside the panel. Next use Traditerm mortar to level the surface of the insulation panel.
  • Finally apply finishing coat to the Traditerm panels, that have been reinforced with Traditerm meshing.

Cautions and recommendations

  • Avoid exposure to direct sunlight while applying and finishing with Traditerm mortar.
  • To fix the panels, spread Traditerm mortar over the surface of the panel and comb with a notched trowel, removing the excess mortar from the joints (of approx 2 cm) to avoid any adhesive protruding between the panels when pressed to prevent thermal bridging.
  • When installing the panels to the substrate, carefully control the flatness.
  • Reinforce all the corners of the panel with reinforcement profiles from the Traditerm System (EWI/ETICS).
  • In areas exposed to impact, strengthen the panels with a double layer of Traditerm mesh.
  • Do not align panel joints on window recesses and corners of openings to prevent the appearance of cracking.
  • Strengthen these joints with mesh strips of 20 x 40 cm placed diagonally and fixed with Traditerm mortar.




The panels should be stored in a dry place, protected from the rain and sun.
This product is considered as non-hazardous for transportation.
