Abstract: Silicone glazing is a translucent glass fabric reinforced material which was produced by coating silicone resin 1-2577 on an open weave leno fabric in a coating tower constructed in Basaisa village, Al Sharkiya Governorate, Egypt. The unique feature of the tower used in this work is the utilization of solar energy for both powering its coating mechanism through the use of a photovoltaic module, and also heating its curing chamber. The optical and mechanical properties of silicone glazing were studied. Silicone glazing is found to have a solar transmission of 90%, an ultraviolet cut-off at 270 nm, and an infrared cut-off at 8.0 μm. The material has a high tensile strength, particularly along the fill and the wrap directions of the reinforcing fabric. The tensile strength tested at 0.8 strain rate is 50, and 80 pli (pounds per lineal inch) at the fill and the wrap directions, respectively. Silicone glazing was found suitable for many solar applications such as greenhouse screen, space solar heating, solar food driers, and skylights in buildings, especially in rural areas.
