68% Ballast Free
SR2 completed wind tunnel testing as one of the lightest ballasted systems on the market with 68% zero ballast in many configurations and wind zones.
SR2 is approved up to 30 degrees and 150 mph!
Complete Ballast Analysis including peel back on corners - no ballasted system should have all the same weights across the system!
Our data is backed by engineering from one the most renown wind engineers in the country,
C. Michael Donoghue, who has worked global including in Dubai, Panama and Saudi Arabia.
