Traditerm® Panel EPS G

Improved thermal insulation panel made of self-extinguishing expanded polystyrene, used in the TRADITERM® external thermal insulation system. The expanded polystyrene panel is used as insulation within the TRADITERM® System both in new and restoration work. Its an excellent thermal insulator thanks to its very low conductivity. Its composition makes it a lightweight and workable material. Its range of thicknesses provide different levels of thermal insulation.

Expanded polystyrene with graphite.

Features and applications

  • Excellent thermal insulation. Very low conductivity.
  • Light and manageable material.
  • Easy to cut.
  • Permeable to water vapor.
  • Range of thicknesses which provide different levels of thermal insulation.

Instructions for use

  • The panels are fixed to the substrate using TRADITERM® adhesive mortar, which is applied to the panel beforehand, using the method of a bead of mortar or a notched trowel. The placement of the panels is done in a staggered way (minimum gap between the vertical joints of the panels of 25 cm).
  • After a minimum of 24 hours, sand down the surface of the panels to correct any slight unevenness.
  • Put fastening anchors into the panels, 8 units per m². The top part of the anchor should be inserted a few mm into the panels. Afterwards the surface over the anchor should be smoothed using TRADITERM® mortar.
  • Finally, coat the panels with TRADITERM® mortar, reinforced with TRADITERM® mesh.


Cautions and recommendations

  • Store the panels in a cool place protected from sunlight.
  • While fixing and coating the panels with TRADITERM® mortar, avoid exposure to direct sunlight.
  • When applying the adhesive mortar to the panels, apply this product 2 cm away from the edges of the panel to prevent the adhesive overflowing and generating thermal bridges when the panel is pressed onto the substrate.
  • Reinforce all the corners of the panels using the profiles available in the TRADITERM® System.
  • In areas exposed to impact, reinforce the panels by using a double TRADITERM® mesh.
  • Avoid joints of panels being aligned with window vertices and corners of holes so as to prevent cracks forming.
  • Reinforce these vertices with 20 x 40 cm strips of mesh.
  • Material is not resistant to solar radiation and organic solvents.


The panels should be stored in a dry place protected from the rain, sun and extreme temperatures.Ultraviolet radiation can cause degradation of the surface of the panel if it is stored directly exposed to sunlight.Product considered Non-Hazardous for transport.
