Schüco CTB solar shading integrated in a façade
Schüco CTB solar shading is active, external shading that is integrated in the façade and offers exceptionally high wind stability. The solar shading is fully integrated in the FW 50+ / FW 60+ / SFC 85 façade and is concealed when retracted. It provides optimum shading for interior rooms and high transparency for views to the outside.

Blind
The blind consists of horizontal, extruded aluminium louvre blades with fixing groove, which are attached to each other by stainless steel cables. The louvre blades are therefore fixed without visible interruption of the outward-facing side of the profile. The blind is retracted between two brackets in a concealed installation space in the façade in front of the intermediate floor. No façade-mounted solar shading headboxes are provided for.
Complete shading must be provided from when the sun is at an angle of 20° with a degree of transparency of at least 23%. When the sun is at an angle of at least 20°, the gtotal value in conjunction with the thermal insulation glazing must be 0.07.
The wind stability of the blind from 30 m/s (11 Beaufort) must be proved by a wind tunnel test with test certificate.
If the solar shading is used in front of opening units which open outwards, it must be ensured that the opening units can only be opened when the solar shading is raised. When the blind is raised, the end strip is not visible.
The louvre blades are made from an extruded aluminium profile and measure 9.3 mm x 9.6 mm. They are positioned at an angle of 45° to the outside and have a convex curvature with a radius of 10 mm. The inward-facing louvre blade has a concave curvature (radius of 13 mm) and has a face height of 8 mm. The louvre blades are anodised to E6 in natural metallic C0 / light bronze C31 / pale bronze C32 / medium bronze C33 / dark bronze C34 / black C35.
The drive shaft must be configured as an extruded hollow profile. The 230 V electric motor is inserted in the shaft and secured against movement along the axes. The blind is connected to the shaft by means of positive and friction-locked, hook-in couplings. The shaft is prepared with sliding and fixed bearings.

The blind is guided by extruded aluminium profiles at the side, which are arranged symmetrically (dimensions: 85.0 mm x 63.5 mm) or asymmetrically (dimensions: 68.0 mm x 63.5 mm). The profiles simultaneously act as façade pressure plates, and their connection to the façade is concealed. An additional bracket system is therefore not required. Two plastic rubbing strips must be integrated in every guide groove. The louvre blades and the guide cap of the end strip run quietly in the guide tracks.

The blind is guided by extruded aluminium profiles at the side, which are arranged symmetrically (dimensions: 85.0 mm x 63.5 mm) or asymmetrically (dimensions: 73.0 mm x 63.5 mm). The profiles simultaneously act as façade pressure plates, and their connection to the façade is concealed. An additional bracket system is therefore not required. Two plastic rubbing strips must be integrated in every guide groove. The louvre blades and the guide cap of the end strip run quietly in the guide tracks.

The blind is guided through extruded aluminium profiles with the dimensions 36.5 mm x 77.0 mm. The profiles act as both façade pressure plates and façade cover caps, and their connection to the façade is concealed. An additional bracket system is therefore not required. Two plastic rubbing strips must be integrated in every guide groove. The louvre blades and the guide cap of the end strip run quietly in the guide tracks.

Installation space
The Schüco CTB solar shading is fixed in a solar shading headbox between two aluminium/steel façade brackets. The façade brackets are structurally load-bearing.

Entry guides
The top attachment of the guide tracks must be designed with plastic entry guides.

Guide rollers
Plastic deflection rollers must be provided, and these must ensure that the blind runs securely in the guide tracks. Guide plates on the side of the outer rollers ensure that the blind retracts correctly.

The shaft is inserted in the bearing brackets from the outside, which must be electro-coated. The bearing brackets and accompanying bearing adapters are mounted on solar shading brackets that are provided on site and must allow for the vertical alignment of the shaft. The shaft is secured in the bearing plates at the front via a locking bar that must be screwed in two places.

Actuator
The drive has a 230 V / 50 Hz tubular motor that is inserted in the shaft and that has a connecting cable (0.5 m long, 4-core, 8 mm diameter) and fitted plug connection. The top and bottom end position can be set electronically using an adjustment cable. The drive has VDE and CE marks and EMV radio suppression seal.

Operation
The blind profiles are raised and lowered using standard flush or surface-mounted switches and host control system (central control, sun monitor, ice monitor, wind monitor, time switch). The end switch integrated in the drive switches the motor off when it reaches the top and the bottom end position.

Colours and surface finishes
The shaft must be plate finish, the louvre blades and the end strip must be anodised and the guide tracks must be anodised / powder coated.
For the louvre blade colours C0 and C31, the plastic clips of the fixing cable must be grey. For the colours C32, C33, C34 and C35, the plastic clips must be black. All other plastic parts must be black.
