The Heart of it All

The masts of this sail type are positioned with a slight diagonal offset. This ensures a stable canvas surface while maintaining an unobstructed view. The mast can also be set up further away from the sail, with longer ropes being used to bridge the extra distance.

  • Two ropes, each with one mast
  • Large shaded area
  • Max. canvas size 6.8 × 7.0 m – 6.0 m x 7.8 m
  • Fully automated operation via remote control and app
  • Unique sense of space due to arched roof design
  • Tailored solution for representative outdoor areas
  • Wind pressure relief system through internal weights or dampers
  • 4 different masts with oval, round and square cross-sections
  • Excellent UV protection | UPF50+
  • High water resistance

Product Information

WeatherMax 80

The ultimate eye-catching feature of any sail system is of course the canvas. C4sun uses the sail material WeatherMax 80, a technically sophisticated fiber that is suitable for sun and rain protection alike. In accordance with criteria we have set, the tailoring of the sail canvases is carried out by one of the leading sail manufacturers in Germany with innovative manufacturing technology and a high level of experience in sailing and yachting.

Mast Models

Four masts made from high-quality, elegant stainless steel or aluminum complete the look of the sail system, forming a perfect harmony with the timeless design of the sail. A specially developed wind pressure relief system inside the mast enables a calm response to higher wind speeds. An internal weight or an internal damper takes care of the necessary balance. Superlative special components such as pulleys positioned on slide bearings prevent this complex mechanism from generating any unpleasant noises, even in the case of high winds. Each design can be combined with any of the C4sun sail masts (exception: elips4sun is not compatible with ID 110 and IG 101).

Motor | Drive | Control and Safety

The sail is driven by a tube motor located inside the roller tube, which can be operated in a number of different ways. First, it can be operated using advanced, secure io-homecontrol® wireless technology featuring a universal communication protocol. This enables all components to communicate with one another, leaving users free to control all comfort and safety elements via a single unit. It is even possible to control and monitor the system using a smartphone. Secondly, the sail can be extended and retracted using a wired controller or a remote control. Alternatively, these functions can be integrated into an on-site KNX (bus) controller.

The power package is another drive variant in which the reinforced drive is provided by two tube motors. This option is recommended for larger sail surfaces and locations featuring high wind speeds. Please note that with certain sail sizes two motors are included as standard equipment.

Roller Tube

C4sun offers multiple installation options with roller tube mounting on walls or rafters being the classic option. Alternatively, the roller tube can be inserted into a free-standing mount on two stainless steel masts – which is equally effective for single and double sail systems. In addition, a customized assembly concept can always be drawn up if required.

Every subsurface is unique, with conditions sometimes varying even within a single surface requiring shade. Practical installation elements are available for each mast to resolve such issues. If that is not the case, users can request an individually-tailored installation concept or freely combine existing mounting elements.

Additional Features

V4A extra protection | Maritime

V4A has been developed for locations that are near to the coast or highly susceptible to weathering. This corrosion-resistant steel alloy provides the surface with added resistance to the elements.

The WeatherMax 80 sail material meets the requirements of UPF50+, the excellent possible ultraviolet protection factor. UPF refers to the inherent level of protection provided by tex- tiles against harmful UV rays.

Wind Stability

C4sun sails feature very high levels of wind stability and safety thanks to their special relief mechanisms in the event of wind pressure. These neutralize the power of the wind by significantly reducing the exposed area, meaning you can continue to enjoy your sail long after conventional systems have been retracted.
