Product Overview
Key Benefits
High Impact & Weather Resistance
Manufactured from UV-protected polycarbonate, VULCAN Prisma resists hail, impacts, and harsh environmental conditions far beyond standard DIY roofing materials.
Optimal Light Diffusion
The unique prismatic texture diffuses sunlight evenly, delivering comfortable illumination without harsh glare — ideal for patios, pergolas, sunrooms, and outdoor living areas
Asthetically Pleasing Argyle Pattern
Argyle Patterns, which consists of interlocking diamonds or lozenges, overlaid in diagonally intercrossing lines, creates a three-dimensional, layered effect, which not only diffuses light, but creates a blurry, bokeh effect when seen through.
Superior Strength & Longevity
With a proven polycarbonate formulation, corrugated profile, and crisscrossed diamond pattern, VULCAN Prisma offers exceptional structural integrity and sustained performance, retaining its properties for years.
Rain Noise Reduction
The prismatic surface helps absorb and reduce the sound of rain and hail, enhancing the comfort of sheltered spaces underneath.
Lightweight & Easy to Install
Highly suited for DIY projects, VULCAN Prisma panels are easy to handle and install, reducing labor time while providing a professional finish.
Balanced Shade & Daylight
Prisma excels in delivering a balance of shade and daylight, preserving visibility while minimizing interior heat buildup and glare.
UV Protection
Co-Extruded with industry leading Avient CESA-Light UV & Light Stabilizers, these sheets protect underlying areas from harmful UV radiation, preventing material degradation and occupant exposure.
Typical Applications
VULCAN Prisma is ideal for a wide range of outdoor and architectural applications, including:
- Covered walkways and breezeways
- Pergolas, patios, and deck roofing
- Carports and sun shelters
- Skylights and greenhouse roofs
- Poolside enclosures and canopy covers
- Residential and commercial shade structures
Color Options, Light Transmission and Effects.
VULCAN Prisma are offered in a plethora of color, light transmission, and specialty materials. Each color variant offers specific light-control benefits, allowing designers and homeowners to calibrate brightness, heat, and ambiance for optimal comfort.
Choose from a variety of colors to suit your aesthetic and functional requirements:
- Valuview Colors: Clear for maximum light transmission and a bright, open feel. Colored options for reduced light projection and alternative flavor.
- Ti-Lite: Exceptional light and shade balance. Metallic colors offer lower transparency, high haze, great shading properties, and most of all, heat reduction.
- Pearly: Pearly, which offers the best balance between light transmission, haze, and heat reduction, while at the same time further enhances Prisma’s aesthetics with an additional pearlescent effect.
- Solar Blue/Green: Solarshield offers what we call Transparent IR Protection, allowing for maximum light transmission and exceptional solar Infra-Red heat control, all in one package.
