What thickness and colors does Strength Reserve Dual Layer come in?
Strength Reserve Dual Layer is available in 15.5mm (12+3.5), 18mm (12+6). Colors: 16 & Custom Pantone Matching. Speckle (90%) and Marbled (100%) colors, all in 15.5mm and 18mm. Custom Pantone matching available — team colors, brand standards, facility identity. View the colors →
What is the difference between virgin and recycled rubber flooring?
Vulcanized virgin rubber is homogeneous with no binder, which gives uniform hardness, resilience and color. It repels sweat, has no rubber odor and has the highest tensile strength and tear and abrasion resistance. Recycled rubber is the more economical choice and comes in Select, Signature and Integrity grades. Compare virgin and recycled rubber →
What is the difference between Strength Reserve and Studio Reserve?
Strength Reserve is the heavier build (15.5mm or 18mm dual layer rolls, 15mm or 18mm tiles) for Olympic lifting, heavy free weight and drop-load zones, and for collegiate and professional training. Studio Reserve is the lighter build (7.5mm to 11.5mm rolls, 6mm or 10mm tiles) for strength and cardio zones, functional and group training, locker rooms, hallways and high school weight rooms.
