Pearly GRECA Series
Metal profile matching GRECA Corrugated Profile design.
Diffused and Cool – Solar selective wavelength penetration.
Soft Diffused Lighting – Filters unwanted wavelengths, retaining cool, diffused GREEN light.
Controlled FIR and NIR – Reduce temperatures by max. 10°C or 50°F.
Weathering Resistant – Avient UV and Light Stabilizers for extra durability and longevity.
Extra light diffusion + High Haze + Balanced light.
Aesthetically pleasing Pearlescent luster.
VULCAN GRECA Polycarbonate profile (76/18)
Our GRECA polycarbonate sheet has the widest span, at 1170mm with 16 corrugations, among all VUCAN corrugated profiles, with a maximum effective covering width of 1100mm.
The trapezoid shape and structure of GRECA truly matches the GRECA metal profile commonly seen in the Americas among other countries, while also providing great structural rigidity and aesthetics, which is commonly used as patio skylights, and walkway coverage among other building projects.
VULCAN GRECA polycarbonate corrugated profile has the same pitch and depth as our ROMA profile, which makes them interchangeable on the same building structure, providing additional choice and a change of taste possible at minimum cost.

Product Overview
Introducing PEARLY GREEN
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.
