Tile roofing traditionally consists of locally available materials such as clay, granite, terracotta or slate, though many modern applications contain concrete. Imbrex and tegula, style dating back to ancient Greece and Rome. Monk and nun, a style similar to Imbrex and tegula, but basically using two Imbrex tiles. Dutch roof tiles, Netherlands
Plastic tiles, marketed as composite or synthetic tiles, became available towards the end of the 20th century. Their exact invention date is unclear, but most became available around the year 2000. [59] [60] Plastic tiles are generally designed to imitate slate or clay tiles, and achieve their color through synthetic dyes added to the plastic.
The characteristics of polycarbonate compare to those of polymethyl methacrylate (PMMA, acrylic), but polycarbonate is stronger and will hold up longer to extreme temperature. Thermally processed material is usually totally amorphous, [ 7 ] and as a result is highly transparent to visible light , with better light transmission than many kinds ...
Lack of accepted standards for measuring light transmittance is a disadvantage for comparing and choosing skylights with plastic glazing. Acrylic is the most common plastic glazing used for dome skylights. However, Polycarbonate and Copolyester materials are also used as glazing, where additional properties such as impact resistance may be ...
Roofing sheets made from twinwall plastic are primarily 10mm thick, however, they are also available in greater thicknesses such a 16mm, 25mm and 35mm. Any thickness over 10mm would usually be called a Multiwall Plastic Sheet due to having multiple internal layers. Twinwall plastic can refer to several different extruded polymers including:
However, while plastic deformation essentially occurs at constant volume, crazing is a cavitation process that takes place with an increase in volume. The initiation of crazing normally requires the presence of a dilative component of the stress tensor and can be inhibited by applying hydrostatic pressure.
