Tongue and Groove

InsulFoam Tongue & Groove (T&G)

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.

Special Features 

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. 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.
