This is a high-quality and low-density, USA-made, EPS foam board insulation for above-grade applications, including building walls, roofs and ceilings.
Note: this (1lb/cubic ft density) insulation is not suitable for use under concrete slabs – instead, use 2lb/ft3 density (most common), 2.5lb/ft3 or 3lb//ft3 types.
Features:
- Made in the USA
- EPS (Expanded PolyStyrene) foam board is cheaper than XPS and outperforms it in long-term R-value retention
- 10 psi type, high density (1 lbs/cu. ft) slab insulation – ideal for between joists
- Suitable for above-grade wall and roof/ceiling installation where permitted
Technical Specifications:
- Insulation Type: EPS (Expanded PolyStyrene)
- Individual Foam Board Size: 4ft wide x 8ft long x 3″ thick (32 sqft)
- R-Value: R-13.05
- Nominal Density: 1.0 lbs/ft3
- Compressive Strength @ 10% deformation: 10 psi
- Manufactured to and Meets: ASTM C518 (R-Value), D1621 (compressive strength), C203 (flex strength), E96 (water vapor permeance), C272 (water absorption), E84 (surface burning characteristics), and C578 (standard specs for rigid polystyrene foam board).
