"SunSquare" sun and rain protection was developed for large balconies, roof gardens and terraces. The motor-driven sailing system is always custom-made according to local conditions, taking into account the position of the sun and the main wind directions. Wind loads are balanced by a spring mechanism. If the wind speed is too high, the sail is automatically wrapped around the central shaft by an electric motor. Length of the shaft up to 10 m. Extension length from sail tip to sail tip up to 13 m. Covered area 10 to 70 m².
Product description
The construction consists of the drive with shaft, steering, sail, supports and fastenings. 4 fastening points are required (for Cantilever three mounting points and for Fold & Roll only one mounting point is required). The shaft must be attached to the floor or the wall of the house on both sides by means of supports. The two ends of the sail are attached to one point each. This is where the greatest loads occur, up to max. 70 kg pull at each end of the sail. The standard case is the attachment of at least two points on the structure and two points on floor supports. In the shaft, a motor, which is connected to an anemometer, automatically rolls the sail in over the wave when wind speeds above 35-50 km / h occur (adjustable). Dynamic wind forces are absorbed by a spring system, because the spring system is connected to the ends of the sail by rollers and ensures that the sail remains taut, but gives way in gusts of wind. In addition, the sail always moves slightly out of the wind. The inclination of the sail is designed in such a way that rainwater can run off. With SunSquare sun sails, large roof gardens, terraces, children's playgrounds, pub gardens, parking spaces etc. can be covered. There are no limits to the application. Up to 70 m² of space can be covered with a sail. Several SunSquare systems next to each other give a maximum of flexibilty.
Simulation
The inventor, Gerald Wurz, sees the special feature of thes awning in two points:
“the sail transforms to an architectural design element and each sail is indivuduall adapted to the structural conditions and the needs of the customer.“
Therefore, the technical requirements have been checked on site, the personal cooperation of the customer is required. In order to give the customer a spatial idea, a 3D-Simulation is shown, using tripods and ribbons that correspond to the outer edges of the sail. In this way, the optimal alignment and position of the awning can be planned one-to-one with the customer. The sail does not have to be arranged symmetrically to the shaft. If the architectural necessity of working with an asymmetrical sail arises on a terrace, for example, this does not detract from the perfect function. The sail are availabe in acrylic (not cleanable) or in PVC (cleanable) fabric. Both are available in several different colors. Carbon ropes are used for the rope hoist, almost exclusively stainless steel for the load-bearing parts. Lighting and height adjusters (manual or electrical) are optionally available (LED spotlights).
Winter garden shading
Another possible application is the winter garden and facade shading. The sail can also be mounted at an extreme angle (up to approx. 35 °). Transparent mesh fabric e.g. with aluminum vapor deposition offer an extended range of applications. A wide variety of light situations can be created depending on the fabric structure and type. In the case of winter garden shading, a light and wind sensor controls the system.
Interior shading
For large indoor area sun- and privacy protection, mesh fabrics are usally used.
