Versico 1.25# InsulFoam Tapered EPS Roof Insulation, 4 ft x 4 ft Panels
Versico 1.25# InsulFoam Tapered EPS is closed-cell expanded polystyrene roof insulation in 4 ft x 4 ft tapered panels, sold in multiple taper profiles including E1 (0.5 to 2.5 in), A2 (1 to 1.5 in), A3 (1.5 to 2 in), C3 (2.5 to 3.5 in), and C4 (3.5 to 4.5 in). It promotes positive drainage, offers a stable long-term R-value, and meets or exceeds ASTM C578.
Key Features:
- Positive drainage: Tapered panels create slope to eliminate ponded water on new and re-roof projects.
- Stable R-value: Thermal properties remain stable over the material's service life with no thermal drift.
- Single-layer install: Can be installed in a single layer for thicknesses up to 40 in, with no complicated filler panels.
- Water resistant: Closed-cell EPS does not readily absorb moisture from the environment.
- Cost-effective: Significantly more cost-effective than extruded polystyrene, perlite, and isocyanurate tapered systems.
- Recyclable: Contains no ozone-depleting blowing agents, may contain recycled material, and is 100% recyclable.
- ASTM C578: Meets or exceeds ASTM C578 for rigid cellular polystyrene thermal insulation.

A: It contains no ozone-depleting blowing agents, may contain recycled material, and is 100% recyclable if removed or replaced.
Expert Verdict — Reviewed by the SuperArbor Pro Desk
Choose the taper profile from the low point of the field: E1 for shallow sumps and crickets, A-series for standard slopes, and C-series where more thickness and drainage are needed. Tapered EPS in a single layer avoids the cost and complexity of filler-panel systems. Confirm fastening or adhesion patterns per assembly type in Versico details.
Store panels flat and protected from sunlight and ignition sources; follow the specified attachment method to resist wind uplift.
Order Versico 1.25# InsulFoam Tapered EPS panels to build positive slope into your single-ply roof.
