Pearly GRECA Series

VULCAN Pearly GRECA Polycarbonate filters unwanted, solar heat radiation. GRECA Polycarbonate Pearly sheets transmit cool, diffused green light.

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 – Clariant UV and Light Stabilizers for extra durability and longevity.

Extra light diffusion + High Haze + Balanced light.

Aesthetically pleasing – Owing to high mother of pearls content.

Description

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

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 GREENspectrum, and retains cool, diffused GREEN light.

This makes it easier to control the climate, particularly in the summer, and maintain optimum room temperature.*
*A large proportion of the heat-inducing far-red light is reflected.

Product Strengths

Pearly Material

Designed as a solar heat protection application that attenuates longer wavelength heat-producing infrared radiation very effectively through reflection, but at the same time, retains cool, diffused GREEN light.

Pearly Technology

With particle sizes ranging from 10~60μm, Pearly is suitable for general-purpose infrared blocking applications.

Light Transmission Rate

Controlled VIS (380~780nm) – 40% Visible Light Transmission Rate

Excellent shading Properties

Perfect for living organisms.

Heat Reflective Properties

Controlled FIR (Far-Infrared) and NIR (Near Infrared) spectrum. Capable of reducing temperatures up to 10°c*.*Certain conditions may apply.

Base Material

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

UV Protective Coating

Co-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 are able to last 10 years or more.

Clean Room Manufacturing

VULCAN Sheets are produced in ISO Class 7 (FED STD 209E equivalent Class 10,000) clean rooms to ensure impeccable quality.

Production Method

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