INSULFOAM TONGUE & GROOVE (T&G) PANELS
INSULFOAM TONGUE & GROOVE (T&G) PANELS
Fire rated EPS substrate for stucco homes
Made from expanded polystyrene (EPS) and used as a substrate for stucco in conventional and manufactured housing, Insulfoam Tongue & Groove (T&G) sheathing provides lasting continuous insulation (ci), superior long-term performance, prevents moisture buildup, and is backed by Insulfoam’s 100% 20-year thermal warranty.
The unique structure of InsulFoam T&G breathes, allowing trapped moisture vapor to escape without effecting insulation performance. EPS is virtually immune to moisture effects, eliminating the need for costly venting procedures.

TYPICAL SPECIFICATIONS
InsulFoam T&G is produced per ASTM C578, Type II with a nominal 1.5 pcf density.
PANELS
InsulFoam T&G insulation panels floats on the studs and absorb building movement without transferring the stress to other joints. The resilience of Insulfoam EPS helps reduce the cracking problems normally associated with stucco walls, allowing stucco to retain its beauty longer.
STABLE R-VALUE
With no thermal drift, T&G’s thermal properties will remain stable over the entire service life. InsulFoam T&G’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.
INSULFOAM INSULATION
InsulFoam T&G creates a thermal envelope of comfort surrounding a building. Up to 35% of the heating or cooling loss that escapes from an average home goes right through the walls. InsulFoam T&G retains its dimensional stability over time, helping to prevent much of that loss.
COST SAVINGS
T&G 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 can be manufactured with an inert additive that deters termites.
CODE APPROVALS
Insulfoam insulations are recognized by the International Code Council Evaluation Service (ICC-ES: ESR 1788), and have numerous Underwriters Laboratory classifications, Factory Mutual Approvals and meets HUD Specifications.
