PLASTBAU® Structural Insulated Panel

The PLASTBAU SIP, made of flame-retardant 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 combination allows the use of very light insulated panels as structural building elements capable of supporting heavy loads on building sites.

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 energy used to heat and cool a home can be reduced by up to 50 percent.

Great Flexibility of Use, Fast, Insulating and Economical

  • Width: 600 to 1200 mm
  • Length: according to project
  • U-value: from 0.5 to 0.15 W/m2K

Key Benefits

Green Building

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

Affordable

PLASTBAU SIP is an effective solution for building quickly, with quality, while reducing the construction costs of insulated buildings.

Fast

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

Insulating

PLASTBAU SIP guarantees maximum insulation, allowing significant savings on energy costs in both extreme heat and cold conditions.
