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 a variety of above-grade building envelope applications. Manufactured from Type 1 EPS, this rigid insulation delivers a long-term thermal resistance of R-3.75 per inch, helping improve energy efficiency while reducing thermal bridging in residential, commercial, and institutional construction. Its stable closed-cell structure provides dependable insulation performance while remaining lightweight and easy to handle. 

Each board measures 2.5" × 24" × 48", covering 8 square feet per sheet. Each bundle contains 10 boards, providing a total coverage of 80 square feet. PlastiSpan® EFS boards are easy to cut, install, and shape for architectural details while maintaining dimensional stability and moisture resistance. Manufactured to meet CAN/ULC-S701.1 Type 1 requirements, they are an excellent choice for high-performance building envelope applications.

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.
