Sun protection for the spa – cantilevered sun sails at the Hotel Royal in Bad Ischl
The Thermenhotel Royal in Bad Ischl offers wellness at the highest level – with a sky lounge on the roof terrace and a dining terrace busy all day long. Both areas were barely usable in the heat; classic parasols blow away in the wind, conventional blinds were structurally out. The brief: sun protection that is wind-stable and shades all day – without intrusive posts.



Spa sun protection: relaxation in any weather
The Thermenhotel Hotel Royal****s in Bad Ischl relies on innovative sun protection that shields guests in sun, wind and rain. The wind-stable sun sails provide large-area shade and blend seamlessly into the design. Thanks to smart control they can be operated centrally and retract automatically in storms – for carefree comfort and an undisturbed wellness experience.

Design concept
The „Sonnenschutz Therme Ischl“ project delivered a shading solution that meets the highest demands, both architecturally and functionally. The combination of intelligently controlled technology, a cantilevered structure and weatherproof material creates a year-round outdoor wellness experience – with no compromise on comfort, safety or the view.
The cantilevered sun sails provide reliable shade and protect guests in rain or strong wind too – with no obstruction to the view.
The well-considered construction keeps the open view of the mountain panorama undisturbed, so the sun sails fit perfectly into the spa concept.
Fixed across old and new buildings and fully tied into the building automation, the sails respond automatically to changing weather – ideal for continuous spa operation with no extra staff effort. As a bonus, the tensioned surfaces add a degree of acoustic separation and so create calmer zones.
