TECNOBOARD is Marvon’s fire board designed and developed to ensure fire resistance up to El 240 of penetration seals on wall and floor according to EN 1366-3.

TECNOBOARD is composed of a mineral wool board coated on both sides with a white intumescent paint.
In contact with fire the paint reacts and expand, thereby preventing the passage of flame and acting as a thermal insulation.

Application field

TECNOBOARD can be used on flexible wall (gypsum), on rigid wall (masonry, concrete and aerated concrete)
and on rigid floor (concrete or aerated concrete).

It has a fire resistance up to El 240 classified according to EN 13501-2 for:

  • Combustible pipes (PVC-U, PVC-C, PE, LDPE, MDPE, HDPE, ABS, SAN+PVC, PP)
  • Combustible soundproof pipes (e.g. Valsir Triplus®, Valsir Silere®, Valsir PP3, Valsir Blackfire®)
  • Insulated and non-insulated multilayer pipes
  • Insulated and non-insulated incombustible pipes (copper or steel)
  • Single or bundled electrical cables
  • Cable trays and corrugated pipes
  • Empty holes

N.B. The board is used in case of large crossing and penetration of mixed services. Seal any remaining gap with TECNO-S 240 sealant.
Use TECNOWRAP intumescent seal in the solutions provided by ETA.
