SUNSKY® PROFILED POLYCARBONATE SHEET
The world’s largest selection of profiles for skylight, sidelight, and roofing applicationsSUNSKY is the leading profiled product for architectural, industrial, and agricultural applications including skylights, sidelights, complete roofs, and cladding.
Weighing half the weight of glass, SUNSKY polycarbonate panels also offer multiple advantages over traditional fiberglass profiled panels (FRP): will not bloom, up to 20 times greater impact resistance, the highest light transmission rates, the lowest yellowing index, the highest load rating, and the highest resistance to wind uplift.
These outstanding properties were confirmed in accredited laboratory testing and in installations worldwide since 1984.

FAQ
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.
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.
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.
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.
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.
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.
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.
