Plasti-Fab Ltd. is a Canadian manufacturer and supplier of expanded polystyrene (EPS) product solutions used primarily in the construction and civil infrastructure industries. The company’s Ajax location at 40 Mills Rd, Ajax, Ontario L1S 2H1, Canada serves as one of its regional operations focused on producing and distributing EPS insulation and related products for residential, commercial, and engineered applications.

What the Company Does

  • EPS Product Manufacturing: Plasti-Fab specializes in expanded polystyrene (EPS) materials — rigid, closed-cell foam plastics that provide insulation, moisture resistance, lightweight fill, flotation products, and structural applications.

  • Construction Solutions: Its products are designed to improve energy efficiency in buildings, provide high thermal performance insulation, and meet the needs of homeowners, builders, and contractors.

  • Vertical Integration: Plasti-Fab is part of a vertically integrated supply chain, meaning it controls multiple stages of EPS production — from raw materials to finished products — which enhances quality and cost efficiency. This integration also makes it one of the larger EPS producers in North America.

Industry & Applications

  • Building Insulation: EPS boards and insulation systems for walls, roofs, and foundations that help reduce heating and cooling energy demands.

  • Structural Systems: Products like structural insulated panels (SIPs) and insulating concrete forms (ICFs).

  • Geotechnical Uses: Lightweight fill, geofoam, and compression-resistant materials for civil engineering projects.
