FREQUENTLY ASKED QUESTIONS

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.

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.

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.

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.

Acrylic edges can be polished by heating them with a torch, blowing hot air on them, or rotating a brush with wax.

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.

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.

Clear corrugated PVC sheets can function as skylights incorporated into metal or other types of roofing. Note that this is only suitable for areas with cold climates.

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.

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.

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.

Palram created specific loading tables for each product. Please visit our website and download the specific catalog.

Yes. Make sure you start installing from the bottom up so the overlaps will not let the water in.

• 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.

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.

The common applications of corrugated PVC sheets are buildings that require opaque coverings and/or are located in highly-corrosive environments such as chemical plants, coastlines, cowsheds, and dairies.

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.

The main benefit of the standing-seam system is that unlike standard sheets, it is sold together with all installation accessories. This system also provides superior water tightness and is easier and faster to install.

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.

A matte surface finish is good if you want to avoid glare within your surroundings.
