Our expectations on aerosun^® roller sails (Sun Furl System) are high, therefore we only use quality materials that have their origins in the yachting sector. All masts and wall anchor plates are made of robust stainless steel profiles with an attractive surface finish (optionally powder-coated) The winding spindle consists of a custom made anodised aluminium chamber profile with internal tubular motor and integrated piping profiles. These serve the possibility for fixation of taut sails and ensure wind stability and safe water drainage during rain. The electric aerosun^® roller sail (Sun Furl System) will be delivered with a wind and rain sensor which protects against excessive loads by uprising wind and heavy rains to retract the system automatically.
