According to the material is divided into glass fiber reinforced polyester light board , honeycomb or solid board made of polycarbon resin , according to the shape can be divided into the same wave with the roof board glass fiber reinforced polyester light board (referred to as glass steel daylighting tile ) and other flat or curved light board .
Glass fiber reinforced plastic daylighting tile has non-colored light transmission type , color light transmission type and opaque , translucent semi-transparent type , glass fiber reinforced plastic daylighting tile surface covered with aging resistance film can be used for 15 to 20 years . When choosing FRP daylighting tile , in order to meet the requirements of daylighting and sandalwood distance , it is better to be thin rather than thick , to avoid the phenomenon of lap porosity is too large and lead to rain leakage , the general thickness of 1.0~2.5 mm , in the thickness selection , it is recommended not to use the practice of people .
Another commonly used polycarbonate board , also known as PC board , is an organic light transmittance board , compared with other light boards , with high strength , good heat insulation , high light transmittance , impact resistance , flame retardant , aging resistance , long service life , good bending performance and so on .
Polycarbonate board can be made of double layer , three layer board , each layer of honeycomb between the plate of different thickness , generally flat type , through type waterproof board and solid type several . Single slab thickness specification to 1 mm , 2 mm , 3 mm , 4.5 mm , 6 mm , 8 mm , 10 mm , 12 mm , double deck slab thickness is 6 mm , 8 mm ,10 mm , 12 mm ,etc . , three layer plate thickness is 16 mm , 25 mm , polycarbonate plate normal width specifications for 2100 mm , length is 6 m , special needs can be discussed with the supplier . Common solid plate type thickness is less than 4.5 mm , can be supplied with coil . When selecting the supplier , it should be required to supply supporting materials , connectors , supporting seals , etc . , and the supplier should provide the construction process description and material performance description , to clarify its support span , temperature expansion and contraction characteristics and solutions , so as to facilitate the construction .
