InsulFoam EG (Exterior Grade) insulation is a versatile product consisting of a superior closed-cell, lightweight and resilient expanded polystyrene (EPS). InsulFoam EG meets or exceeds the requirements of ASTM C578, Standard Specification for Rigid, Cellular Polystyrene Insulation.
- R-4
- Environmentally Friendly. Insulfoam Exterior Grade Insualtion does not contain any ozone-depleting blowing agents, may contain recycled material and is 100% recyclable.
- Stable R-value. With no thermal drift, IEG's thermal properties will remain stable over the entire service life. InsulFoam IEG's thermal stability makes it eligible for an Insulfoam 20-year thermal performance warranty.
- Proven Performance. EPS has been manufactured using the same chemistry since the mid-1950s, providing proven performance.
- Water Resistance. Insulfoam Wall Insulation does not readily absorb moisture from the environment, and offers exceptional wall system moisture management.
- Code Approvals. Insulfoam insulations are recognized by the International Code Council Evaluation Service (ICC-ES), and have numerous Underwriters Laboratory and Factory Mutual Approvals.
- Cost Savings. IEG insulation is typically less expensive than other rigid insulations, offers the highest R-Value per dollar over other rigid insulation
- Insect and Mold Resistance. Insulfoam Insulation is naturally decay resistant and manufactured with borate which is an inert additive that deters termites.
