Polycarbonate sheets, owing to its high clarity and visible light transmission rate amongst plastic materials, are the most widely used glazing material on roofings, skylights, greenhouses and wall claddings.
Valuview Solid Flat profile sheets come in six colors -
• High VIS Clear
• High VIS Blue
• High VIS Green
• High VIS Grey
• High VIS Bronze
• Diffused Opal
VULCAN Valuview SOLID Flat polycarbonate sheets keep visible light transmission rates identical to glass and allows maximum visible and solar light transmission. Different colors can be achieved by simply adding color master-batches, which creates a whole new atmosphere to the covered area.
With time, growing knowledge, improvements in manufacturing and the constant development of proprietary additives, we have come to understand the advantages of using polycarbonate in place of traditional glazing material.
Polycarbonate sheets are 250 times over glass, 10 times over FRP and Acrylic sheets in impact strength, in addition, its light weight, ease of installation, fireproof and weathering resistant properties make them the perfect choice as flat roofing sheets for civil construction and safety glazing.
For example, sheets 6mm and above are capable of stopping low powered rounds, and often laminated to create bulletproof glass to stop higher powered rounds or complex security threats; PC sheets can also be molded into riot shields for law enforcement.
VULCAN Valuview Series is targeted towards projects seeking optimal price versus value.
VULCAN Valuview come in 6 standard colors and fully customizable in size and length to meet your requirements. Special colors can also be produced upon request.
For example, Valuview Solid Flat sheets is the most popular of all the clear flat roofing sheets we offer, with its transparency offering high visible light and solar transmission identical to standard clear glass, but at almost half the weight and 250 times its strength.
All VULCAN polycarbonate sheets carrying the Valuview name use 100% Virgin UV stabilized Covestro resin. As an added option, sheets can be co-extruded with Clariant CESA-Light UV and Light Stabilizers for extended lifespan and added protection against light transmission losses and yellowing caused by excessive exposure to solar radiation.
Base MaterialVULCAN polycarbonate sheets use only 100% Virgin Covestro UV stabilizer included master-batch.
UV Resistant CoatingCo-extruded with the Base Material, the Clariant CESA Light UV and Light Stabilizers blocks harmful UV rays from 280~400nm. With co-extruded UV protection, VULCAN Polycarbonate sheets last 10 years or more.
Production MethodCo-Extrusion ensures evenly spread, evenly thick base material and UV coating.
Clean Room ManufacturingVULCAN Sheets are produced in ISO Class 7 (FED STD 209E equivalent Class 10,000) clean room to ensure an impeccable quality.
