Soft Stride is a dense foam underlayment that provides excellent sound reduction under laminate and engineered flooring. The closed cell foam design provides excellent moisture protection and fights against mold and mildew. The overlap flap helps seal out moisture and easily attaches with an adhesive strip.

Both tests measure sound transference from an upper level room to a lower level room. The IIC measures sound such as moving furniture and walking, while the STC measures sound such as voices and television. Minimum sound rating required by most building codes and architects is 50.
