Tecnowrap

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

TECNOWRAP is composed of an intumescent graphite based reactive material that in case of fire reacts sealing the crossing.

Application field

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

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 (Valsir Triplus®, Valsir Silere®, Valsir PP3, Valsir Blackfire®)
  • Multilayer pipes.
  • Incombustible pipes.

N.B. The annular space around TECNOWRAP is sealed with TECNOBOARD.
