AplaXFoam extruded polystyrene for walls


The technology for obtaining extruded polystyrene granules by extrusion provides extruded polystyrene boards a uniform structure of closed cells, which confers them specific technical features: low level, long term thermal conductivity, excellent mechanical resistance, no capillarity, high moisture resistance, resistance to cycles (frost-thaw), high durability, high resistance to vapour diffusion, low weight and easy handling, easy to cut with simple tools, resistant to root action, clean, odourless and non-irritant to the skin.


  • Heat insulation of exterior walls, non-circulable terraces, wood frame roofs
  • Heat insulation of floors built over cold rooms 
  • Boards incorporated into the flooring, suspended ceilings below roofs,
  • Structural element strength enhancing works (thermal bridge insulation, cladding of basement walls, etc.)
  • Heat insulation repair works on terraces, impact noise acoustic insulation as floating slab


  • Good thermal insulator (low λ coefficient)
  • Slight retention of water and moisture
  • High mechanical resistance
  • Self-extinguishing properties
  • Resistant to acid and alkali aggression
  • Inertia in temperature variations
  • Compatibility with materials used in construction (cement, gypsum)
  • Easy to carry, cut, and apply
