Valuview ROMA Series
Valuview Series – Owing to polycarbonate’s high clarity and visible light transmission rate amongst plastic materials, Valuiew Series are the most widely used glazing material on roofings, skylights, greenhouses, and wall claddings.
Valuview ROMA profile sheets come in six colors –
• High VIS Clear
• High VIS Blue
• High VIS Green
• High VIS Grey
• High VIS Bronze
• Diffused Opal
Clear Corrugated Roofing Sheet (Valuview ROMA Series)
VULCAN Polycarbonate Corrugated ROMA (76/18) Profile
ROMA is one of the most common polycarbonate clear corrugated roofing sheet 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.
With the already high refractive index of clear polycarbonate, and added reflection and refraction properties from its curved profile, ROMA clear corrugated roofing sheet is, for example, one of the best choices for greenhouse projects and areas which require indirect light penetration.

Product Overview
Introducing VALUVIEW Series
VULCAN Valuview Series is targeted towards projects seeking optimal price versus value.
VULCAN Valuview comes in 6 standard colors and is fully customizable in size and length to meet your requirements. Special colors can also be produced upon request.
For example, ROMA Valuview clear sheets is the most popular of all the clear corrugated roofing sheet 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 Avient 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.
Product Strengths
Base Material
VULCAN polycarbonate sheets use only 100% Virgin Covestro UV stabilizer included master-batch.
UV Resistant Coating
Co-extruded with the Base Material, the Avient 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 Method
Co-Extrusion ensures evenly spread, evenly thick base material and UV coating.
Clean Room Manufacturing
VULCAN Clear Corrugated Roofing Sheet is produced in ISO Class 7 (FED STD 209E equivalent Class 10,000) clean room to ensure impeccable quality.
Light Transmission Rates
Projects which require direct light projection
• Valuview Clear: 88%
Projects which require reduced light projection
• Valuview Blue: 40%
• Valuview Green: 40%
• Valuview Grey: 26%
• Valuview Bronze: 25%*
