Composition of the lighting material itself does not have water absorption. Glass lighting roof mainly by the glass, steel, aluminum, sealant, lining material composition. The material itself does not plastic or composite shutters leak in non-destructive situations. Water treatment measures are limited in space. High strength and light material composition, space occupied volume compared to other materials smaller, especially the thickness of the gap is very limited, which means that the form of waterproof construction requirements and more difficult.

Roofing glass is located in the top of the building and the horizontal angle of less than 75 degrees of glass surface layer. So the catchment area is relatively vertical glass curtain wall, including wind and rain caused by strong water hit more directly. The sunlight acts more pickets old wood rotting bench directly on the surface of the lighting roof, including heat and ultraviolet light. It is easier to produce a variety of materials, thermal deformation of the roof.

The anti-ultraviolet ability and heat aging resistance of the sealing material are important factors to ensure the waterproofing of the lighting roof. The surface of the lighting roof can not be considered Composite Horse Fencing Brand Manufacturer similar to the glass surface so smooth. The glass surface of the plate surface deflection will cause water and fouling, especially the seam at the seam and buckle plate shape will bring water and fouling, this part is very easy to bring water and beautiful adverse consequences.

The gap is the main channel for the roof leakage. And the gap is formed by splicing and joining between the same material and the heterogeneous material. The surface tension of water is the cause of capillary phenomenon. The effect of capillary penetration on tectonics and crevice plastic wood panels for exterior walls waterproofing should not be overlooked.
