Corrugated Polycarbonate Sheets for Roofing, Skylights & Sidelights

Designed to meet complex engineering challenges, SUNTUF corrugated polycarbonate sheets are ideal for industrial roofing and cladding, and for commercial skylights and daylights.
SUNTUF offers all the unique properties of polycarbonate: mechanical robustness, durability, light transmission, UV protection, and strength-to-weight ratio. Unlike corrugated metal sheeting and reinforced glass panels, SUNTUF installs quickly and easily, and maintains its appearance and features for years.
SUNTUF polycarbonate profiles can be adapted to match any corrugated metal profile structure using Palram MetalMatch™ technology. This makes daylighting industrial and commercial spaces quick and easy.


UV protection, durability, and light transmission of up to 90% are some of the benefits of polycarbonate SUNTUF roofing.

Show FAQs
Which material diffuses the light better?
The diffusion is not defined by the material, but by the diffusion additive that is part of the manufacturing formula. The materials should be selected by their fit to the application (e.g. polycarbonate for thermo-forming or extreme weather). Usually products marked with sign grade and/or diffusion grades have greater light diffusion than others.
Will polycarbonate light transmittance deteriorate over time?
PALRAM’s polycarbonate products are shielded with a UV protection layer that guards against photodegradation, yellowing, and brittleness. This protects the sheets from the harmful impact of UV radiation and helps to maintain light transmittance and quality for many years. Our products come with a 10-year warranty against loss of light transmittance. Upon special request, we can provide an enforced UV protection layer with a longer warranty.
Can I cover my old polyethylene greenhouse with polycarbonate while still keeping the old structure?
Can I retrofit my old glass house with polycarbonate sheets?
Yes, Palram’s MetalMatch technology enables us to create a covering that will fit any existing structure without requiring any additions.
When should I specify a matte surface finish for the polycarbonate?
What is the meaning of Shading Coefficient (SC)?
Shading coefficient (SC) is a parameter that compares transparent and translucent materials with clear 3 mm glass with 87% LT ׂ(light transmission). The lower the value, the more convenient it is to stay under the material on warm, sunny days. In architectural projects, the SC should usually be between 0.3 to 0.5.
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.
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.
Can I install corrugated PVC and polycarbonate sheets horizontally for siding?
How do I design the secondary steel support spacings for roofing/siding?
Can corrugated sheets be curved?
Yes. Corrugated sheets can be cold-curved to create arched shapes. It’s important to follow the relevant Palram specifications for minimum radius in cold-curving, which can be found in the Installation Instructions of the relevant sheets. In addition, corrugated sheets should be arched so that the corrugations themselves are curved lengthwise.
If polycarbonate sheets block UV radiation, why is there a “UV-side” that faces outwards?
Polycarbonate sheets block UV radiation by absorbing it. This absorption mechanism can cause degradation to the material, and to prevent this from happening, the sheet is coated with a special material. For this reason, it is recommended that the sheets are installed with the marked UV protective layer facing outward. Moreover, most of the sheets are only protected on the side that is clearly marked as such.
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 install corrugated polycarbonate sheets as a skylight?
Corrugated polycarbonate sheets are installed as a homogeneous part of the metal roof. For more information, please review Palram’s installation instructions for the desired profile.
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.
Should products be pre-dried before thermoforming?
This depends on the production date and storage conditions of the product before thermoforming. It is recommended to check the product before thermoforming is attempted.
How do I reduce the heat build-up coming from the façade into the building?
In order to reduce heat build-up through the façade, Palram strongly recommends the use of its tinted SolarSmart™ panels. SolarSmart™ tints can be implemented in all Palram polycarbonate products. For more information, reference the Palram SolarSmart™ technology page.
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.
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 determine the color, Light Transmission (LT) and haze properties of polycarbonate?
This decision depends on the application – some of the colors are transparent and some are translucent. If a see-through material is needed, then haze should be smaller than 1% and the LT% should be based on the illumination design. If a translucent effect is needed, then the haze should be 100% and the LT% based on the chosen color.
Can the percentage of light transmission be controlled? I need a lot of light but I need it to be diffused.
Palram offers various LT% parameters – from 0% to 90%. In addition, we offer a color called a “diffuser” that allows 85% of the light in while diffusing it by 100%. The result is a light-transmitting panel that is not transparent but is highly translucent.
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.
