Guangdong Ruifeng New Materials Co., Ltd.

1. Building exterior shading functions: ventilation louvers engage effectively against sunlight on the indoor radiant heat, reduce the room temperature in summer can reach efficacy. At the same time the intensity is good, not easy to be destroyed. By adjusting the ventilation louver opening angle so that the interior can not only control the angle of the light, but can also increase security, privacy effect is relatively good. 2. Large-scale construction of high windows, a large area of ventilation: ventilation shutters with electric opening device can effectively solve the plant. Difficult to open part of the window, the ventilation requirements. When fully open (90 °) ventilation rate of 99%, excellent ventilation function: Rainy Day can also be ventilated work. After the windows do not have to consider rain water or security problems. Civil theft shade, various places Universal: plant exhaust ventilation. Building Exterior facade performance, anti-typhoon set, improve ventilation settings, protection settings can be accessed through the school's ventilation louvers of different settings.shutters with electric opening device can effectively solve the plant.
