R+ EPS Slab Insulation is designed to meet today’s energy code requirements while lowering labor and material costs for residential slab-on-grade construction. With built-in features like pre-cut tack strips and snap-board scoring, R+ Slab Insulation speeds up installation and ensures long-term thermal performance.
Key Benefits
- IECC compliant: Meets insulation requirements for all residential climate zones.
- Durable plastic facers: Improve moisture resistance, handling, and jobsite performance.
- Labor-saving options:
- Tack Strip Board — pre-cut 45° bevel for slab edge insulation.
- Snap Board — pre-scored at 24″ widths for fast snapping without tools.
- Protects waterproofing during backfill.
- Stable R-values: Maintains insulation value over time, resistant to freeze–thaw cycles.
- Outperforms XPS: Retains nearly twice as much R-value after 15 years compared to extruded polystyrene.
- Cost effective: Same thermal performance as other rigid insulations, but at a fraction of the cost.
Recommended Applications
- Slab-on-grade floors
- Vertical slab edge insulation
- Under-slab insulation (light and heavy floor loads)
- Garages, driveways, and walkways
- Residential remodels and new construction
