Lámina corrugada transparente para techos (serie Valuview ROMA)
Perfil VULCAN Policarbonato Corrugado ROMA (76/18)
ROMA es una de las láminas para techos corrugadas transparentes de policarbonato más comunes en el mercado, compatible con muchos techos de metal en muchos países y, en general, un perfil sobresaliente que ofrece propiedades físicas superiores y buenas propiedades refractivas.
El perfil ROMA se puede diseñar como un panel de techo de policarbonato, así como un panel de revestimiento de paredes. Una de las mayores ventajas de las cubiertas de perfil ROMA de policarbonato es su forma de arco. Combinado con las propiedades superiores de flexión y tracción del policarbonato, crea un panel para techos y un panel para revestimiento de paredes extremadamente fuertes y confiables.
Con el ya alto índice de refracción del policarbonato transparente y las propiedades adicionales de reflexión y refracción de su perfil curvo, la lámina corrugada transparente para techos ROMA es, por ejemplo, una de las mejores opciones para proyectos de invernaderos y áreas que requieren penetración de luz indirecta.

Introducing VALUVIEW Series
VULCAN ValuviewSeries 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
Material de base
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 an impeccable quality.
Light Transmission Rates
Projects which requires direct light projection
