Assuming a sheet of 5/8" plywood would be used two times per week and the maximum number of times it can be used is ten times, this translates into 10.4 weeks in a year (52 ÷ 5 = 10.4).  The following calculations indicate a substantial savings using Alturnamats vs. plywood over a six-year period.

Plywood

            10.4            Number of weeks a sheet of plywood can be used per year
            x 12            Number of 4' x 8' sheets in this example

          124.8            Total sheets of plywood used each year
            x   6            Number of years in this analysis

          748.8            Total sheets used in six years
          x $20            Cost per sheet of 5/8", 4' x  8' plywood (per 84 Lumber)

      $14,976            Total plywood cost for six years

Alturnamats - Limited Lifetime Warranty

            $235            Approximate cost of 4' x 8' Alturnamat
            x 12            Number of mats in this analysis

        $2,820            Total Alturnamats cost for six years

Conclusion

            $14, 976            Plywood Cost
            -   2,820            Alturnamats Cost

            $12,156            Savings over six-year period

NOTE:  Above plywood analysis does not include the numerous trips to a lumber yard or disposal of worn out plywood.
