Public buildings or commercial buildings often adopt daylighting roof structure to improve the natural daylighting rate and permeability of buildings. While increasing natural lighting, permeability and beauty, it also increases other adverse effects. Especially at noon in summer, the radiation of the sun is too strong, resulting in too strong light and temperature rise in the building. Bring discomfort and excess air conditioning energy consumption. In order to solve this contradiction, it is necessary to set up reasonable sunshade facilities for daylighting roof.
Glass lighting roof can generally be set from the outside of the lighting roof shading and from the inside of the lighting roof shading two ways, referred to as external shading and internal shading. However, in large shopping malls, gymnasiums, Hotel atriums, office halls and other places with high vertical height of daylighting roof, if the inner sunshade system is used, there are many problems such as difficult installation, poor sunshade effect, late maintenance and poor safety, while the outer sunshade system perfectly avoids these problems.
The selection and design of shading schemes are usually based on the interior and exterior decoration, pattern, shading requirements and so on. The commonly used sunshading schemes for daylighting roofs include electric ceiling shading and louver shading.
Electric ceiling curtain is generally divided into two types: scroll type and folding type, which are mainly used for sunshade of lighting roof. Among them, the roll-type electric ceiling curtain is flat and stretched when unfolding, while the fold-type electric ceiling curtain is even and wavy when unfolding. Usually, the price of the scroll electric ceiling curtain is higher, and the decorative effect of the foil should be more neat and concise. The scroll electric ceiling curtain mainly includes FSS and FTS electric ceiling curtain. The folding electric ceiling curtain is mostly used in FCS electric ceiling curtain.
Louvers are usually used for shading of daylighting roofs, including European louvers and flat louvers. They are used for internal or external shading of daylighting roofs. Generally, the effect of external shading is better, but the relative wear of sunshading products installed outdoors is larger. European louvers are more inclined to be installed inside the daylighting roof. The biggest advantage of louver shading products is that they can adjust the blade rotation angle relatively accurately, and can adjust the amount of light entering well, so as to achieve fine dimming.
Fundamentally speaking, the basic functions are similar. Individual places need to be matched with the environment. Generally speaking, they are determined by personal preferences. Professional design scheme, excellent product quality and perfect technology are the essential elements of modern glass lighting roof electric shading.
