The PLASTBAU ® SIP, made of “Flame Retardant type” Expanded PolyStyrene (EPS) with embedded C-shaped zinc-coated steel reinforcing profiles, takes advantage of the structural integration of two materials: EPS and Steel. This alliance allows to use very light insulated panels as structural building elements, able to support heavy loads in the building yards.
Main Features:

  • Thickness from 60 to 200 mm
  • Width: 600 – 1200 mm
  • Length: any, according to the project
  • U-value: from 0.5 to 0.15 W/m2K

Great flexibility of use, fast, insulating and economical.

Dimensions and thickness can be adapted on the project.

The PLASTBAU ® Structural Insulating Panel is our most versatile product. Its adaptability to every kind of construction extends its field of application to reinforced concrete- and dry-buildings. The main applications are:

  • Structural walls
  • External Curtain Walls
  • Internal Partition Walls
  • False Ceilings
  • Roofs
  • Off Site bidimensional and tri-dimensional structures
  • Prefabricated Buildings



The PLASTBAU ® SIP, taking advantage of the EPS insulating properties, allow you to build zero energy buildings which can perfectly adapts to all climate.


PLASTBAU ® SIP is the perfect system to build fast, with quality and allows you to decrease construction costs of insulated buildings.


Thanks to its lightness, manageability and installation speed, constructions time can be reduced up to 30%.


PLASTBAU ® SIP garantees maximum insulation, allowing a significant saving of energy costs, in extreme heat and cold conditions.
