Direction-selective systems in the roof

Directionally selective systems that are transparent and translucent from one preferred direction and opaque and sun-blocking from another direction are preferably suitable for the roof area.

Directional selectivity: South light control

Solar utilization possible
Blocking out overheating summer sun
View into the southern sky

Directional selectivity: North light deflection

Protection of the interior from direct sunlight
Uniform, diffuse room illumination
View into the northern sky

In east- and west-facing roof surfaces, the light control systems can be installed from the eaves to the ridge (vertically) and can be used to direct either north or south light. However, retro systems are preferably installed horizontally valley. In the roof area, the retro systems are integrated as a fixed inlet in the cavity of insulating glass. Depending on the pitch of the roof, internal retro systems are also available that can be blinded or rotated.

The illustrations show the options for light control and shading in flat roofs and north and south-facing sheds. Which system is used, is determined by the use of the interior space. In museum or sports buildings,
direct light ingress from the south is generally prevented. The interior is illuminated exclusively by daylight from the northern sky. In passive solar architecture, the flat southern sun is used and only the high summer sun is blocked out.

RETROFlex in flat roofs

Micro-structured slats in an upright position deflect the overheating sun from the south and allow the zenith and light from the northern sky to flood in. A very good vertical view and zenithal light entry for good room illumination is guaranteed.

The slat spacing and the slat tilt angle are adjusted for low roof pitches.

RETROLux in flat roofs

The RETROLux inverse slats are mirrored on the upper side. The underside is matt white. The slats are installed with openings facing north on the interior side. The light deflection is monoreflective for the southern sun. North light is deflected downwards into the interior. The slats are installed in a fixed position.
The illustrations refer to the RETROLuxTherm 12 mm slat type. Depending on the task, the RETROLuxTherm micro can also be used for special shading tasks.

RETROLux under the glass roof

The RETROLux 75mm slats can also be installed in the roof in a similar way.

RETROFlex is suitable for all roof glazing and roof pitches. The high sun is blocked out even with a flat slat pitch. A good, horizontal view between the slats is always guaranteed.

Slat spacing and slat inclination are calculated according to the building physics and lighting requirements of the interior.

RETROLux in the roof

The folded slats such as RETROLux Standard or RETROLux micro are suitable for all pitched roofs, regardless of the compass direction and roof pitch. The folded slats such as RETROLux Standard or RETROLux micro are suitable for all pitched roofs, regardless of the compass direction and roof pitch. The design also takes into account the specific use of the rooms under the glass roof to ensure freedom from glare.
