The application area of Skylight sheet use for steel structure industrial Workshop roof and wall lighting, agricultural vegetable greenhouse thermal insulation lighting, public stadium roof lighting, There are also many lighting areas such as warehouses, greenhouses, stations, terminals, airports, commercial buildings.
1. The skylight sheet needs a pilot hole before fixing it. The hole diameter must be greater than 50% of the width of the fixing screw to avoid internal stress expansion and cracking of the skylight sheet caused by thermal expansion and contraction.
2. When the skylight roof sheet and the corrugated color metal sheet overlap vertically, the minimum overlap length must be 200mm, and two butyl tapes should be attached.
3. When fixing the transparent lighting sheet, the self-tapping screw must with the flooding washer, so that it is between the screw and the tiles, so that it is waterproof and dustproof. After inserting the waterproof washer into the screw, lock it into the purlin with an electric drill to complete the fixing of the sheet.
4. The skylight tile does not need to overlap within 12m, and it needs to overlap over 12m. The length of the overlap is 200-400mm, and two Butyl tapes apply at the overlap. The horizontal overlap does not need to close.
5. During the construction of the skylight tile, it is not allowed to step on the wave directly with feet, so as not to crack the sheet. A 1200mmx300mm (length x width) non-slip thick wood board must place in the horizontal position of the panel, and the guide holes and fixing screws of the lighting sheet must be stepped on.
1. There can be similar shapes of wavy and profiled color metal sheets, which can overlap together.
Common models are: Type 666, Type760, Type820, Type840, Type900, Type990
2. The lighting sheet is astigmatic, and the transmittance is high, which can effectively block most ultraviolet rays.
The daylighting board has significantly improved the lighting effect of broad and deep buildings. Even the most straightforward internal and external flat-type lighting sheet can effectively increase the illuminance at the indoor distance of 4 ~ 9m from the window and improve the uniformity of daylighting throughout the room. The effect is particularly apparent in the early morning and evening when outdoor natural light is low, and when the height angle of the sun in summer is high.
The upper window used by the daylighting board is small, which will not severely increase the air conditioning load. Moreover, the lighting sheet introduces sunlight into the room through the upper window and plays a role of external shading for the large lower window. It can see from the simulation results that the load on the air conditioner significantly reduce after using the lighting board. The energy-saving effect will be more apparent when the optimized lighting board used.
