VULCAN Polycarbonate Corrugated ROMA (76/18) Profile
ROMA is one of the most common profiles on the market, compatible with many metal roofings throughout many countries, and in all, an outstanding profile that offers superior physical properties and good refractive properties.
ROMA profile can be designed as a polycarbonate roofing panel as well as a wall cladding panel. One of the biggest advantages of polycarbonate ROMA profile roofing is its arch shape. Combined with the superior flexural and tensile properties of polycarbonate, creates an extremely strong and reliable roofing panel and wall cladding panel.
Product Overview
PEARLYGREEN
VULCAN Pearly GREEN has been designed as a solar heat protection application that attenuates longer wavelength heat-producing infrared radiation very effectively through reflection, but at the same time, allowing a high percentage of cool, diffused GREEN light to pass through.
Pearly GREEN have particle sizes in the range of 10~60μm, and is suitable for general-purpose infrared blocking applications.
Pearly GREEN reflects rather than absorbs heat producing far-red solar radiation without affecting the transmittance of the GREEN spectrum, and retains cool, diffused GREEN light.
Product Strengths
Pearly Aesthetics
Who says heat blocking has to be dull and opaque? VULCAN Pearly use natural mother of pearls to create that impeccable iridescence, beautiful from any angle while retaining adequate visible light penetration, perfect for indoor and outdoor applications.
Redefines the meaning of an aesthetically pleasing Polycarbonate sheets by creating a Pearlescent affect. Pearlescence is an effect related to iridescence, where the reflected surface light gives off a pearl-like luster.
