Tred-MOR Carpet Tile Cushion provides premium, luxurious comfort through a "bounce back" only felt when walking on a premium SBR rubber product. It comes in 54" width x 60' rolls, allowing one contiguous layer under any carpet tile installation. This provides 100% coverage of the subfloor beneath the carpet tile, reducing potential problems due to an abundance of seams. Even with a cushion-backed carpet tile, vulnerability exists at every seam where sound will penetrate through to the subfloor. Tred-MOR "locks out" unwanted sound, while it "locks in" comfort and privacy.
