Twin Acustic EPS T/045 PP

TWIN_STAND_black_3858x3858_square

Boards produced by method of expanding (foaming) polystyrene. Dedicated for thermal and sound insulation in water-based underfloor heating systems. The external layer of boards is covered with polypropylene foil with imprint to facilitate the distribution of heating pipes. The boards are equipped with foil overlaps for covering joints upon installation.

  • Accesible sizes: 2000 x 1000 [mm]
  • Thickness: 22/20, 33/30, 43/40
  • Edges: smooth

Application

  • sound insulation of all floors in floating floor systems under operational load below 4,0 kN/m2
  • thermal insulation in water-based underfloor heating systems in one-family, multi-family and public utility development
