External venetian blinds

Products

Grinotex Sinus - The external venetian blind with metal joints Sinus from Griesser

Description

The Sinus slats not only look good, they can also do a lot. The curved form guides intrusive light rays to the ceiling. A comfortable ambiance is thus guaranteed. And if you'd rather have it darker, Grinotex Sinus can also be fully closed using the sealing lip.

Grinotex III Sinus - External venetian blind with metal joints with use of daylight

Better use of daylight, reduced glare in the typical shading position of about 45°.
Metal composite technology with guided slats on both sides. Steel wire cable with black plastic sheathing (UV stable) for direct connection of the slats. Lateral lifting mechanism with steel roller chain. Automatic safety locking device in every position. Safety sensing edge prevents destruction of the blind in the event of collisions with obstacles. The blinds can be lowered either in an open or closed position, as desired. Aluminium slats flanged on both sides with a rolled-in, sound-absorbing sealing lip and guide nipple on both sides, stove-enamelled in Premium Colors. Lower profile (end profile) and guide rails made of extruded aluminium, anodised colourless. Guide rails with weather resistant, sound-absorbing inserts. Upper rails (housing) of galvanized sheet steel with Comfort Drive or articulated crank drive for the lifting and turning system.

Option: Open slat-lowering position (operating position).
The shading with lowering of the blinds is often annoying – particularly at the workplace. The slat-lowering position of around 48° prevents these dark stages while lowering the blind.
