Valuview GRECA Series

Valuview Series – 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.

VULCAN GRECA (76/18) Polycarbonate sheet has the widest span, at 1170mm with 16 corrugations, of all VUCAN corrugated profiles.

GRECA profile is most often seen in the Americas.

VALUVIEW Series

VULCAN Valuview Series is targeted towards projects seeking optimal price versus value.  VULCAN Valuview come in 5 standard colors and fully customizable in size and length to meet your requirements.  Special colors can also be produced upon request.  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.


Product Strengths

Base Material 
VULCAN polycarbonate sheets use only 100% Virgin Covestro UV stabilizer included master-batch.

UV400 Coating
​Co-extruded with the Base Material, our Optical Grade UV400 Covestro (Bayer) master-batch, blocks harmful UV rays from 280~400nm. With UV400 coating, VULCAN Polycarbonate sheets are able to last 10 years or more.

Production Method
Co-Extrusion ensures evenly spread, evenly thick base material and UV coating.

Clean Room Manufacturing
VULCAN Sheets are produced in Class 5000 clean rooms to ensure an impeccable quality.

Light Transmission Rates
Projects which requires direct light projection.
• Valuview Clear: 88%

Projects which requires reduced light projection.
• Valuview Blue: 40%
