PlastiSpan EFS insulation used in EIFS applications covers the outside of the building so that the structure is isolated from the wide temperature fluctuations of the climate. This reduces expansion and contraction of the structure and stabilizes interior temperatures. When using PlastiSpan EFS insulation in EIFS applications it provides a complete exterior blanket of insulation in a simpler manner than application of insulation on the interior.

PlastiSpan Insulation is code listed with CCMC 12424-L and meets the requirements of CAN ULC S701.1, Type 1.

PlastiSpan EFS insulation is manufactured under a stringent quality control program to meet the requirements of EIFS manufacturers that includes third party certification of material properties.

PlastiSpan EFS insulation can be supplied to any thickness required to provide specified thermal resistance (R-Value) and special shapes can be provided that will create the style or form needed for the building.

  • Meets all building code requirements
  • Thermal resistance - RSI 0.65/25 mm (R-value 3.75/inch)
  • Most cost-effective insulation per R-value
  • Closed cell insulation resists moisture
  • Easy to cut and install
  • Maintains R-value
  • Can be used in Retrofit & new construction
