SUNTOP® Corrugated Foamed Polycarbonate Sheets

Durable lightweight foamed polycarbonate solution for residential roofing

SUNTOP corrugated foamed polycarbonate is a lightweight roofing & siding product that is opaque, rigid and highly impact-resistant. It can withstand garden rocks, golf balls and even baseballs (see the video below). SUNTOP roofing sheets are available in rich solid colors that provide 100% shade and protection from harmful UV radiation. SUNTOP solutions can also endure the full range of hot and cold temperatures, and even the most severe weather conditions. Whether you are a contractor or do-it-yourselfer, SUNTOP is easy to install.

Rich, bold colors & 100% shade

SUNTOP roofing sheets are available in three opaque colors that each provides 100% shade (as compared to SUNTUF which is transparent or translucent and lets light shine through). The color swatches below are provided for reference only as onscreen colors may vary. Visit your local dealer to see the actual panels. You can also request samples from your dealer.




So tough, other panels are jealous

SUNTOP residential PVC roofing sheets are tough and won’t dent like typical corrugated metal panels for DIY applications. SUNTOP easily withstands snow, ice and temperatures ranging from -40° to 212 °F (-40° to 100° C). In addition, with more rigidity and up to 20 times more impact resistance than fiberglass, SUNTOP offers the best hail protection available in opaque polycarbonate products. See how well SUNTOP holds up to garden rocks, golf balls and baseballs in this video.

Frequently Asked Questions

How do I curve the polycarbonate to follow the façade curve?
+ -

All Palram polycarbonate products can be cold bent onsite during installation, subject to a minimum radius. The radius varies based on the chosen product. For flat sheets such as PALSUN & SUNLITE, the rule-of-thumb for the minimum radius is the thickness multiplied by 200. Please check the Palram catalog for more detailed specifications.

How do I specify the required thickness of the polycarbonate glazing material?
+ -

The recommended thickness of the polycarbonate glazing material is based on factors such as wind & snow load, panel size, and boundary conditions. Visit the Palram website for access to calculators that can help you determine the recommended thickness.

What is the minimum allowed bending radius of polycarbonate?
+ -

The minimum allowed bending radius of the polycarbonate is 200 times the thickness of the sheet, for example, a 2 mm sheet has a minimum 400 mm bending radius.

Why do I have to pre-drill fastener holes in roofing with corrugated panels?
+ -

Pre-drilling the holes ensures that the panels have room to expand and contract properly with temperature changes. Skipping this step can lead to distorted, warped or cracked panels.

How do I design the secondary steel support spacings for roofing/siding?
+ -
Can I install corrugated PVC and polycarbonate sheets horizontally for siding?
+ -
How do I clean the polycarbonate?
+ -

  • Never use abrasive or high alkaline cleaners on any Palram polycarbonate products.
  • Do not leave cleaners on Palram polycarbonate for extended periods of time. Rinse immediately with cold, clean water.
  • Do not apply cleaners in direct sunlight.
  • Never use sharp objects, squeegees or razors on polycarbonate.
  • Do not clean with gasoline.
  • Always practice safety first and never step directly on a polycarbonate panel.
  • Always test cleaners in a small inconspicuous area prior to cleaning the entire panel to ensure against adverse results.
  • Avoid allowing the pressure washer spray tip to come too close to the panel. Pressure washers often have enough pressure at the spray tip to penetrate or tear the panel.
  • Avoid dry cleaning as sand and dust particles clinging to the exterior of the panels may scratch the surface.

How do I combine corrugated polycarbonate sheets (SUNTUF) with metal sheets?
+ -

With Palram's MetalMatch technology, we can perfectly match almost any trapezoid industrial metal sheet and install SUNTUF as a homogeneous part of the roof.

When should I use PVC corrugated sheets versus polycarbonate corrugated sheets?
+ -

PVC corrugated sheets are mainly used for opaque roofing and siding of industrial buildings in highly-corrosive environments such as port warehouses, cowsheds, and dairies. Polycarbonate corrugated sheets are mainly used as roofing or siding where natural daylight illumination is needed.

Where should I use corrugated versus multiwall polycarbonate covering?
+ -

SUNTUF Plus corrugated polycarbonate sheets provide the best light transmittance and UV light resistance, with exceptional load bearing and impact-resistance properties. SUNLITE Plus multiwall PC sheets provide the best thermal insulation. In locations where you would prefer thermal insulation to light transmission, you should use SUNLITE Plus multiwall PC sheets.
