The Plasti-Fab PlastiSpan® EFS Type 1 EPS Insulation Board is a lightweight, closed-cell expanded polystyrene (EPS) insulation board designed for Exterior Insulation and Finish Systems (EIFS), continuous insulation, and above-grade building envelope applications. Manufactured from Type 1 EPS, this rigid insulation provides a long-term thermal resistance of R-3.75 per inch, helping improve building energy efficiency while reducing thermal bridging. Its lightweight construction makes it easy to handle, cut, and install, making it an excellent choice for residential, commercial, and institutional projects.

Each board measures 3" × 24" × 48", covering 8 square feet per sheet. Each bundle contains 8 boards, providing a total coverage of 64 square feet. With a nominal thermal value of R-11.25, PlastiSpan® EFS offers dependable long-term insulation performance while resisting moisture absorption and maintaining dimensional stability. This product meets CAN/ULC-S701.1 Type 1 requirements and is supplied as a Special Order item, sold by the bundle with no returns.

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.
