Bio-Based Tile, or BBT, uses a polymer called BioStride that contains bio-based rapidly renewable ingredients. The tiles can be used where composition tile currently is used; no new training, equipment, or cleaners for maintenance purposes are necessary. BBT features twice the indent resistance, five times greater impact resistance, and is two-and-a-half times more crack resistant than composition tile. Twenty-eight neutrals and colors coordinate with any design. armstrong.com; 717.397.0611.
