The basic functions include ventilation, shading and concealment, and now the elements that used indoors are gradually moving outdoors and becoming an important element of the building facade. There is a sealed slot between the blade and the connecting piece, and a sealed ring and sealing strip between the blades to ensure that the louver can be isolated from external noise, dust, wind and rain when completely closed. The adjustable angle of the hundred blades can ensure the indoor natural ventilation, and at the same time can prevent outdoor harmful ultraviolet radiation: Automatic fire exhaust and ventilation combined, connected with the fire system, in emergency, can be automatically opened to achieve the effect of smoke exhaust ventilation.

The system characteristics

1.Lighting and shading :The sheet is slightly curved ,beautiful in shape and optional in color .Reduce the pressure of forward wind when closing , and the turning angle of the blade can be adjusted between 0 to 180 degree . The turning angle of the blade can be adjusted according to the angle of sun expose to achieve the best effect of shading and dimming.

2.Ventilation: strong protection, typhoon Nemesis blade is slightly curved, closed to reduce the pressure of the forward wind, not affected by wind (including typhoon), strong safety protection of building Windows, glass exterior walls.

3.Heat preservation, heat insulation, noise reduction: when the blades are closed, the sash is airtight, and the hundred blades are double hollow design, which can effectively maintain the indoor temperature and isolate the outdoor high temperature, and can reduce the noise of more than 30 db.

4.Fire control: can receive fire signals, such as smoke sensor, temperature sensor probe, fire emergency button, and receive the signal sent by the fire control center, as an automatic smoke exhaust cooling gate.

5.Occasion : factory smoke exhaust ventilation, civil sunshade anti-theft. Building exterior facade surfaces, typhoon protection Settings, improved ventilation Settings, school protection Settings, etc., can be achieved through different design or installation methods of ventilated shutter curtains.
