PLASTBAU® Structural Insulated Panel

PLASTBAU® Structural Insulated Panel (SIP)

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. T

Air barriers or vapor barriers are not required in PLASTBAU® SIP buildings because properly sealed SIPs create a code compliant air barrier with a permeability rating of less than 1.0 perm. A PLASTBAU® SIP building envelope provides high levels of insulation and is extremely airtight, meaning the amount of energy used to heat and cool a home can be cut by up to 50 percent.

Great flexibility of use, fast, insulating and economical

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 such as:
  • Structural walls
  • External Curtain Walls
  • Internal Partition Walls
  • False Ceilings
  • Roofs
  • Off Site 2D and 3D structures
  • Prefabricated Buildings
Dimensions and thickness can be adapted on the project.
Technical Features
  • Thickness: from 60 to 200 mm
  • Width: 600 – 1200 mm
  • Length: according to project
  • U-value: from 0.5 to 0.15 W/m2K
Green Building

The PLASTBAU® SIP, takes advantage of the EPS insulating coefficient, allowing to build zero energy buildings which can perfectly adapt to all climates.


PLASTBAU® SIP is the perfect system to build fast, with quality and allowing 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 guarantees maximum insulation, allowing a significant saving of energy costs, in extreme heat and cold conditions.
